[R] Is there a summary on different version of 'apply' functions?What is the meaning of the prefixes?

Problem is, various packages have added their own apply-type functions; so
what you get depends on what packages you have downloaded.

Hi,

There are quiet a few different 'apply' functions, such as lapply,
sapply and many more. I'm very familiar with the 'Apply' function in
Mathematica. Can somebody point me a summary of all the 'apply'
functions in R. Also, I'm curious that what 'l' and 's' (and other
prefixes) stand for in 'lapply' and 'sapply'

Regards,
Peng
