JohnMount / base_fns.R

Created March 23, 2018 14:25

Small strengthenings of base R functions to be more pipe compatible.



	# Re-expose basic R data manipulation tools in more pipe friendly wrappers.
	library("wrapr")

	#' Evaluate an expression with a data frame acting as the inner environment.
	#'
	#' References can be forced to the environment with a .e$ prefix
	#' and forced to the data frame with a .d$ prefix (failure to
	#' lookup returns null). Only works on in-memory data.frames.
