Is there a way to get a vector with the name of all functions that one could use in R?可能重复：有没有办法获得一个可以在R中使用的所有函数名称的向量？
Hi
你好
I would like to get from R the list of functions loaded in the environment.
I know ls() that gives the list of objects loaded. But some objects are not functions.
I would like to clean my env from the functions but not from the other objects (matrices, array etc) that contain some of my result that dont want to lose.
我想从R获得环境中加载的函数列表。我知道ls（）给出了加载的对象列表。但有些对象不是函数。我想从函数中清除我的env，而不是从包含我不希望丢失的一些结果的其他对象（矩阵，数组等）中清除。
Any idea?

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

ok, I have a proposal
好的，我有一个建议
rm(list=ls()[sapply(ls(), function(obj) "function"==class(eval(parse(text = obj)))[1])])
I am sure there is something more elegant.
我相信有更优雅的东西。
