Keep your environment clean

A small utility which makes selective objects removing easier.

You can install eponge package from CRAN:

install.packages("eponge")

or from GitHub:

# install.packages("devtools")
devtools::install_github("krzjoa/eponge")

Many times we can meet a situation, when we want to clean our environment selectively. Suppose we just wrote a couple of functions, which have the same names as the ones existing in already attached libraries.

filter <- function(x, id){
  x %>% 
  filter(ID == id)
}

cars <- 1:5

eponge::erase_masking()

Sometimes, we may want to tidy our messy enivironment: we have objects we would like to keep, while in the same time there are many temporary objects created during the exploration.

cars.2 <- cars
cars.2$speed <- cars.2$speed + 2

new.iris <- iris[1:20, ]

add_two <- function(x) x + 2

# Normally, we don't have to pass envir argument, because it indicates global environment by default
eponge::erase_data(envir = environment())

Package was originally named sponge, but it was changed in order to avoid name conflict with BioConductor package SPONGE. The current name comes from its French equivalent, éponge (e.pɔ̃ʒ).
