# pivta
`pivta` is an R wrapper of the [WebDataRocks](https://www.webdatarocks.com/) JavaScript library. The package allows you to implement an interactive pivot table (among other data analysis features) throughout an HTML Widget.
The library supports CSV and JSON data. __Note that this is a free version of the WebDataRocks library, as such the data file uploaded should not exceed 1MB__. Nonetheless, that's fair for most modest data sets
You can install the development version of `pivta` from Github using:
```{r, eval=FALSE}
# install.packages("remotes")
remotes::install_github("feddelegrand7/pivta")
```
# How to use pivta
Just run `pivta()` and start playing ! The function has three main arguments:
+ _dsource_: Optional. Allows you to specify ex-ante the location of the csv/json data frame, by providing a URL.
+ _sep_: The CSV data frame separator. Defaults to comma (","). Will be ignored if data is JSON.
+ _report_: Optional. Allows you to specify ex-ante the location of your JSON report file (see below).
In Shiny, you'll have to use the `pivtaOutput()` and `renderPivta()` functions.
# Examples
Let's work with the [CSV](https://gist.githubusercontent.com/feddelegrand7/b366864aabf9653361f461cbf972d97c/raw/a62c4672f2f5824b2634a66c948e6258d7c65323/mpg.csv) file of the [mpg](https://ggplot2.tidyverse.org/reference/mpg.html) data frame. You can upload the file locally or specify its URL using the __source__ argument.
```{r, eval=FALSE}
library(pivta)
pivta()
```
We can make some cool analysis:
You can easily change the aggregation measure. Here let's take a look at the Average:
Too many numbers after the decimal ? no worry, it's possible and easy to format the results:
You can export your results into different format :
The results can also be saved into a JSON file. If you want to retrieve the results the next time that you open your Shiny app you can either upload it locally or store it remotely and provide a URL that points to the report (within the __report__ argument of the `pivta()` function).
Below an example of the usage of `pivta()` on Shiny:
```{r, eval=FALSE}
library(shiny)
library(pivta)
library(ggplot2)
ui <- fluidPage(
h1("The Pivot Table"),
pivtaOutput(outputId = "pivot_table"),
h1("The Plot"),
plotOutput(outputId = "plt1")
)
server <- function(input, output) {
output$pivot_table <- renderPivta({
pivta(dsource = "https://gist.githubusercontent.com/feddelegrand7/b366864aabf9653361f461cbf972d97c/raw/a62c4672f2f5824b2634a66c948e6258d7c65323/mpg.csv")
})
output$plt1 <- renderPlot({
ggplot(mpg, aes(cty, hwy)) +
geom_point(col = "#324C63")
})
}
shinyApp(ui = ui, server = server)
```
Finally, feel free to try the other features provided by the WebDataRocks JS library. You can read the complete documentation [here](https://www.webdatarocks.com/doc/)
