In some computing subcultures, the term "grapes" refers to the percent sign, which R uses to name binary operators such as `%*%`. Here, `grapes` is an R package that turns arbitrary functions into binary operators. As with the [magrittr pipe](https://CRAN.R-project.org/package=magrittr/vignettes/magrittr.html), this allows you to avoid cumbersome parentheses in your code.

```{r}

library(grapes)

grow(rbind, c, from = "base") # Use `from` to specify a package or environment to search.

bunch() # see the operators (grapes you have grown)

nrow(sleep) # 20

longer = sleep %rbind% sleep %rbind% sleep # No clumsy parentheses!

nrow(longer) # 60. Most of us would like to sleep longer.

1 %rbind% 2 %c% 3

```

# Installation

To install the development version, get the [devtools](https://CRAN.R-project.org/package=devtools) package and run

```

devtools::install_github("wlandau/grapes", build = TRUE)

```

If you specify a tag, you can install a GitHub release.

```r

devtools::install_github("wlandau/[email protected]", build = TRUE)

```

# Tutorial

The [online package vignette](https://github.com/wlandau/grapes/blob/master/vignettes/grapes.Rmd) has a complete tutorial. You can load the compiled version from an R session.

```r
