reinstallr
==============
[](https://github.com/calligross/reinstallr/actions)
[](http://cran.rstudio.com/package=reinstallr) [](http://www.r-pkg.org/pkg/reinstallr)
`reinstallr` is a tool to identify missing packages, e.g. after upgrading R, by scanning through your R files. If the missing packages are available on CRAN and you confirmed the install, `install.packages` is called. As a bonus, it provides some information about the packages you are using.
`reinstallr` is a little helper I wrote for myself and I'm glad if it's useful for anyone else. **Pull requests to improve the package are very welcomed!**
`reinstallr` searches for
* `library()`,
* `require()` and
* `package::function`/`package:::function` calls.
Installation
------------
`reinstallr` is available on CRAN (stable) or via `devtools::install_github` (dev)
```r
install.packages('reinstallr')
```
```r
if (!requireNamespace("devtools", quietly = TRUE))
install.packages("devtools")
devtools::install_github("calligross/reinstallr")
```
Usage
------------
```r
reinstallr(path = NULL, pattern = NULL, ...)
```
Per default reinstallr searches the working directory for R, Rmd, Rnw, Rhtml and Rpres files. After a reinstall the following might be enough to install all packages (from CRAN):
```r
# All my R projects are located in ~/Documents/R/
reinstallr(path = '~/Documents/R/')
```
`show_missing_packages()` searches for missing packages and checks if the package is available on CRAN:
```r
show_missing_packages(path = '~/Documents/R/')
# package on_cran
# 1 lineprof FALSE
# 2 BuBa FALSE
# 3 metricsgraphics TRUE
```
If you would like to find out, which packages you use, `show_package_stats()` is your friend:
```r
show_package_stats(path = '~/Documents/R/')
# [...]
# 43 testthat 3
# 44 htmltools 4
# 45 lubridate 4
# 46 reshape2 4
# 47 twitteR 4
# 48 data 5
# 49 rstudioapi 5
# 50 scales 5
# 51 jsonlite 7
# 52 dplyr 10
# 53 knitr 11
# 54 htmlwidgets 12
# 55 ggplot2 17
# 56 rhandsontable 17
# 57 microbenchmark 18
# 58 shiny 34
```
`find_used_packages()` gives you the information, in which files a package is used:
```r
find_used_packages(packages = c('dplyr', 'ggplot2'), path = '~/Documents/R/')
```
