# ggcalendar
[](https://lifecycle.r-lib.org/articles/stages.html#experimental)
*Note: This README walks through package rational and contains the code that defines proposed package functions and in addition to first-cut testing. [TLDR - Jump to traditional readme content](#traditional-readme)*
Here's a proposal for creating calendars with ggplot2 via Stat extension.
When using calendars, 'when?' and 'where?' are the same question! So, ggcalendar introduces a new positional aesthetic: 'date'. Let's *put* things on the calendar!
In this proposed package, we'll specify the position of a calendar event calendar using dates as the required aesthetic: `aes(date = my_variable_of_dates)`! Then you can use layers function `stat_calendar()` and derivative geom functions `geom_text_calendar`, `geom_tile_calendar` and `geom_point_calendar` to place specific grobs/mark in the plot space.
Under the hood, the compute_group functions finds the x and y position for the date in the month (x is day in week and y is week in month). Faceting by month is used to prevent over-plotting. Note: automatic faceting by month via ggcalendar() function presupposes that your variable is also named 'date'.
Other possible directions would be to calculate x and y based on date in month *and* on month - instead of relying on faceting by month. Furthermore, a dedicated Coord could be created (Teun's thought). Then maybe dates would just feed generically in as the 'x' aes - this sounds cool!
```{r setup}
# library(ggcalendar)
library(ggplot2)
library(lubridate)
library(tidyverse)
```
``` r
# install.packages("devtools")
devtools::install_github("EvaMaeRey/ggcalendar")
```
# Step 00. Convenience functions, dates vectors to data frames.
Because ggplot2's diet is consists solely of dataframes, we create a number of convenience functions that will help us produce dataframes with column 'date' we can feed into ggplot2.

data.frame(date =
df_dates_interval(start_date,

}
```
## Examples
Let's have a look at some of these.
```{r}
df_today()
df_day()
df_dates_interval(start_date = "2024-10-02", end_date = "2024-10-04")
df_week()
df_year() |> head()
df_month() |> head()
return_df_hours_week() |> head()
```
# Step 1 & 2. Compute: from date to x/y, & define StatCalendar
The computation that we want to be done under the hood relates to translating the here-to-fore unknown positional aesthetic 'date' to the first-class 'x' and 'y' positional aesthetic mappings, as well as variables that can be used in faceting (month).
```{r}
knitrExtra:::chunk_to_r("get_week_of_month")
```
As a pre-step to computing many useful variables from our date variable, we focus on this (currently messy) conversion of vectors of dates to week of the month.
```{r get_week_of_month}
get_week_of_month <- function(x){
(- lubridate::wday(x) + lubridate::day(x)) %/%
7 + 1 +
ifelse(lubridate::wday(lubridate::floor_date(lubridate::as_date(x), "month")) == 1, 0, 1)
}
```
Next, we'll define a compute group function. A number of variables are created by parsing our date variable.
Then, we'll pass all this computation to define a new ggproto object StatCalendar. For maximum flexibility, our compute function doesn't create ggplot2 core aesthetic channels 'x', 'y', and 'label' variables, but instead uses the default_aes field to state what should be first interpreted as x, y and label (thoughts? Maybe only 'label' should be managed like this).
```{r}
knitrExtra:::chunk_to_r("compute_group_calendar")
```
```{r compute_group_calendar}
compute_group_calendar <- function(data, scales){
data |>
dplyr::mutate(wday = lubridate::wday(.data$date)) |>
dplyr::mutate(wday_abbr = lubridate::wday(.data$date, label = TRUE, abbr = TRUE)) |>
dplyr::mutate(week_of_month = get_week_of_month(.data$date)) |>
dplyr::mutate(day = lubridate::day(.data$date)) |>
dplyr::mutate(year = lubridate::year(.data$date) - 2018) |>
dplyr::mutate(month_abbr = lubridate::month(.data$date, abbr = TRUE, label = TRUE)) |>
dplyr::mutate(hour = lubridate::hour(.data$date)) |>
dplyr::mutate(year_academic = lubridate::year(.data$date) +
ifelse(lubridate::month(date) >
6, 1, 0)) |>
dplyr::mutate(month_academic_abbr = .data$month_abbr |>
factor(levels = c("Jul", "Aug", "Sep", "Oct", "Nov", "Dec",
"Jan", "Feb", "Mar", "Apr", "May", "Jun")))
}
StatCalendar <- ggplot2::ggproto(`_class` = "StatCalendar",
`_inherit` = ggplot2::Stat,
required_aes = c("date"),
compute_group = compute_group_calendar,
default_aes = ggplot2::aes(x = ggplot2::after_stat(wday),
y = ggplot2::after_stat(week_of_month),
label = ggplot2::after_stat(day)))
StatWeekly <- ggplot2::ggproto(`_class` = "StatCalendar",
`_inherit` = ggplot2::Stat,
required_aes = c("date"),
compute_group = compute_group_calendar,
default_aes = ggplot2::aes(x = ggplot2::after_stat(wday),
y = ggplot2::after_stat(hour),
label = ggplot2::after_stat(hour)))
```
## Test it out
Okay, let's see how our compute and Stat work in action!
```{r}
df_week() |>
compute_group_calendar()
df_month() |>
ggplot() +
aes(date = date) +
layer(stat = StatCalendar, geom = "text",
position = "identity")
```
# Step 3. Let's write a user-facing function `stat_calendar()`
```{r}
knitrExtra:::chunk_to_r("a_stat_calendar")
```
```{r a_stat_calendar}
#' Title
#'
#' @param mapping
#' @param data
#' @param geom
#' @param position
#' @param na.rm
#' @param show.legend
#' @param inherit.aes
#' @param ...
#'
#' @return
#' @export
#'
#' @examples
stat_calendar <- function(mapping = NULL,
data = NULL,
geom = "text",
position = "identity",
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE, ...) {
ggplot2::layer(
stat = StatCalendar, # proto object from Step 2
geom = geom, # inherit other behavior
data = data,
mapping = mapping,
position = position,
show.legend = show.legend,
inherit.aes = inherit.aes,
params = list(na.rm = na.rm, ...)
)
}
```
### Test `stat_calendar`
```{r}
df_year() |>
ggplot() +
aes(date = date) +
stat_calendar(color = "grey") +
facet_wrap(~month(date, label = T, abbr = T)) +
scale_y_reverse()
```
# aliasing and convenience
To give the user a better sense of what they'll see when using stat_calendar we create the alias, 'geom_text_calendar()'.
```{r}
knitrExtra:::chunk_to_r("geom_text_calendar")
```
```{r geom_text_calendar}
#' Title
#'
#' @param ...
#'
#' @return
#' @export
#'
#' @examples
geom_text_calendar <- function(...){stat_calendar(...)}
#' Title
#'
#' @param ...
#'
#' @return
#' @export
#'
#' @examples
geom_point_calendar <- function(...){stat_calendar(geom = "point", ...)}
#' Title
#'
#' @param ...
#'
#' @return
#' @export
#'
#' @examples
geom_tile_calendar <- function(...){stat_calendar(geom = "tile", ...)}
```
# `defaults_calendar` & `ggcalendar()` Thinking about set of scales/coords etc, that gives you a nice calendar (to wrap up into defaults)
In our test of stat_calendar, we see cumbersomeness. Below, we consider even more ggplot2 decision that would make our plot easier to consume and more beautiful.
```{r}
day_labels = c("S", "M", "T", "W", "T", "F", "S")
df_year() |>
ggplot() +
aes(date = date) +
stat_calendar(color = "grey") +
ggplot2::aes(date = date) +
ggplot2::scale_y_reverse(breaks = 5:0,
expand = c(0,0),
limits = c(6.5, 0.5)) +
ggplot2::scale_x_continuous(breaks = 1:7,
labels = day_labels,
limits = c(.5, 7.5),
expand = c(0,0)
) +
ggplot2::facet_wrap(~lubridate::month(date, abbr = T, label = T), scales = "free") +
ggplot2::labs(x = NULL, y = NULL) +
ggplot2::theme(axis.text.y = ggplot2::element_blank(),
axis.ticks.y = ggplot2::element_blank(),
axis.ticks.x = ggplot2::element_blank()) +
ggplot2::theme(panel.grid.major = ggplot2::element_blank()) +
ggplot2::geom_blank()
```
## `defaults_calendar` & `ggcalendar()`
Then, we bundle these up into defaults_calendar, which can be quickly added for converting to a more polished and readable calendar.
```{r}
knitrExtra:::chunk_to_r("defaults_calendar")
```
```{r defaults_calendar}
#' Title
#'
#' @param day_labels
#'
#' @return
#' @export
#'
#' @examples
defaults_calendar <- function(day_labels = c("M", "T", "W", "T", "F", "S", "S")){
week_start <- getOption("lubridate.week.start", 7)
if(week_start != 1){day_labels <- day_labels[c(week_start:7, 1:(week_start-1))]}
list(
ggplot2::scale_y_reverse(breaks = 6:0,
expand = c(0,0),
limits = c(6.5, 0.5)),
ggplot2::scale_x_continuous(breaks = 1:7,
labels = day_labels,
limits = c(.5, 7.5),
expand = c(0,0)
),
ggplot2::facet_wrap(~lubridate::month(date, abbr = T, label = T), scales = "free"),
ggplot2::labs(x = NULL, y = NULL),
ggplot2::theme(axis.text.y = ggplot2::element_blank(),
axis.ticks.y = ggplot2::element_blank(),
axis.ticks.x = ggplot2::element_blank()) +
ggplot2::theme(panel.grid.major = ggplot2::element_blank()),
ggplot2::geom_blank()
)
}
```
Let's check it out...
```{r}
df_year(2024) |>
ggplot() +
aes(date = date) +
stat_calendar() +
defaults_calendar()
```
Furthermore, we provide ggcalendar as an alternative point of entry into the ggplot framework. The default data frame is even included (the current calendar year), so a full calendar will print with no additional specification.

# data defaults to calendar year and aes(date = date)
The following feels a little weird to me, but is allowed.
A grammar of graphics fundamental is that a statistical graphic are composed of geometries/marks that take on aesthetics (color, position, size), to represent a variable.
Below we aren't aren't fully stating these specifications; which feels a bit funny; I would not recommend this as a starting point.
