How can I load a bunch of packages at once with out retyping the require command over and over? I've tried three approaches all of which crash and burn.
Basically, I want to supply a vector of package names to a function that will load them.
x<-c("plyr", "psych", "tm")
require(x)
lapply(x, require)
do.call("require", x)
Several permutations of your proposed functions do work -- but only if you specify the character.only
argument to be TRUE
. Quick example:
lapply(x, require, character.only = TRUE)
