santoku is a versatile cutting tool for R. It provides `chop()`, a replacement 

for `base::cut()`.

## Installation

Install from [r-universe](https://r-universe.dev):

``` r

install.packages("santoku", repos = c("https://hughjonesd.r-universe.dev", 

                                      "https://cloud.r-project.org"))

```

Or from CRAN:

``` r

install.packages("santoku")

```

Or get the development version from github:

``` r

# install.packages("remotes")

remotes::install_github("hughjonesd/santoku")

```

```{r, child = 'advantages.Rmd'}

```

## Examples

```{r}

library(santoku)

```

`chop` returns a factor:

```{r}

chop(1:5, c(2, 4))

```

Include a number twice to match it exactly: 

```{r}

chop(1:5, c(2, 2, 4))

```

Use names in breaks for labels:

```{r}

chop(1:5, c(Low = 1, Mid = 2, High = 4))

```

Or use `lbl_*` functions:

```{r}

chop(1:5, c(2, 4), labels = lbl_dash())

```

Chop into fixed-width intervals:

```{r}

chop_width(runif(10), 0.1)

```

Or into fixed-size groups:

```{r}

chop_n(1:10, 5)

```

Chop dates by calendar month, then tabulate:

```{r}

library(lubridate)

dates <- as.Date("2021-12-31") + 1:90

tab_width(dates, months(1), labels = lbl_discrete(fmt = "%d %b"))

```
