What are sapply and lapply functions in apply familly?

21k

For an example of a specific lapply method, see lapply,List-method in the S4Vectors package (defined for List objects).

The apply functions (apply, sapply, lapply, and so on) are slightly faster than a standard for loop, but they still loop in R rather than in lower-level C code.

Clarification: The mapply() function is a multivariate apply of sorts that applies a function to a set of inputs in simultaneously. 5.
