# purrr2for
Concerned about R performance?
Automagically convert R/`purrr` syntax code blocks into efficient Julia `for` loops
with a simple Addin. No writing of Julia/RCpp code itself, the converter is feature-complete
with both R's `purrr` and `*pply` family and writes the required Julia code.
## Installation
You can install the released version of purrr2for from [GitHub](https://github.com/jonocarroll/purrr2for) with:
``` r
devtools::install_github("jonocarroll/purrr2for")
```
## Example
If you have a code block written in R (`purrr` or `*pply` loop)
``` r
map(1:10, function(x) x^2)
```
the Addin will convert this into a Julia call for you
``` Julia
map(x -> x^2, 1:10)
```
This can be wrapped in a [`JuliaCall`](https://cran.r-project.org/web/packages/JuliaCall/index.html) block and run inline.
