In heavywatal/namaespace: Utility to create dummy R packages for namespace

namaespace

namaespace provides a function to create a dummy R package that imports and exports other packages' functions. The goal is to create a temporary namespace through which you can call those functions.

The latest version can be installed from github with

devtools::install_github('heavywatal/namaespace')

Usage

library(namaespace)
load_in_namespace('myns', c('pkg1', 'pkg2', 'pkg3'))
myns::pkg1_func()
myns::pkg2_func()

Functions select() and rename() from dplyr often get masked by other packages. To avoid such conflicts, you had to write the package names explicitly like dplyr::select(). But it is very hard to remember where those functions are loaded from (dplyr? tidyr? or purrr?). It will be convenient if you can call those functions through an easy-to-remember namespace like tdy.

Some essential packages (from tidyverse and Bioconductor) are pre-defined.

load_in_namespace('tdy', pkgs_tidyverse)
iris %>% tdy::select(ends_with('Width'))

load_in_namespace('bio', pkgs_bio)
hg19 %>% bio::select(keys=..., columns=...)
