install_deps: Recursively Parse R Files in a Directory, and Install...
In brendan-R/brocks: The Personal R Functions of Brendan Rocks

Description Usage Arguments Value

install_deps (recursively) finds R code files in a directory, and uses regular expressions to find code that looks like it refers to an R package (via extract_package_deps). It then extracts the names of all of these packages, checks that they're not already installed, and that they are on CRAN, and then installs them (via install.packages).

1 2	install_deps(dir = getwd(), file_pattern = "\\.R$\|\\.Rmd$", cran_mirror = cran_repo(), ...)

`dir`	The directory to search for R files to parse
`file_pattern`	A regular expression used to determine whether a file should be parsed or not. The default will parse only `.R` and `.Rmd` files
`cran_mirror`	The CRAN mirror to use. The default calls a small function which returns the Rstudio mirror, if no current default exists
`...`	Passed to `install.packages`
