Sample R Configurations

On this page:

• Single configuration file with relative paths

Single configuration file with relative paths

• Encouraged: ```

  Use of file.path() for platform neutrality

  basepath <- file.path(“My Documents”,”Paper 15”)

  alternatively, if using Git

  basepath = rprojroot::find_root(rprojroot::is_git_root)

includes <- file.path(basepath,”includes”) inputdata <- file.path(basepath,”inputdata”) tables <- file.path(basepath,”text/tables”) matsize <- 11000

### Use of relative paths in main program for inclusions

 Discouraged:

source(“C:\My Documents\yesterdays programs\submodule.do”)

- Encouraged:

source(file.path(includes,”submodule.R”))

or

source(file.path(“includes”,”submodule.R”)

### Installing packages in a project-specific directory

- using the `packrat` package
- using `containerit` package
- manually resetting the R library locations in the config file, then installing packages

Install packages locally

.libPaths( c( includes , .libPaths() ) )

You can then create a single dependency file that is run before all others:

00_install.R:

run this only when updating the packages

all packages necessary to run the main.R have

been included in this replication package

include “config.R” install.packages(‘rddensity’, lib=libpath, destdir=libpath) install.packages(‘rdrobust’, lib=libpath, destdir=libpath) install.packages(‘gridExtra’, lib=libpath, destdir=libpath) install.packages(‘ggplot2’, lib=libpath, destdir=libpath)

and in your main program

basepath = rprojroot::find_root(rprojroot::is_git_root) source(file.path(basepath,”config.R”)) library(rdrobust) library(rddensity) library(gridExtra) library(ggplot2) ``` will always work, because it no longer requires download, and fixes the version of the packages used.
