Get the list of functions loaded in R's global environment [duplicate]

See ?lsf.str

X <- lsf.str()as.vector(X) # just for printing purposes, you can use the vector in rm()rm(list=X)

function r environment-variables

ok, I have a proposal

rm(list=ls()[sapply(ls(), function(obj) "function"==class(eval(parse(text = obj)))[1])])

I am sure there is something more elegant.
