[R] Finding code for R functions

Greetings, I am trying to figure out how to find the source code for R functions. I am specifically interested in finding the code for the "prcomp" function. I know that typing the function name without parenthesis will lead to the code (or to a .Internal or .FORTRAN or .C call).

Re: [R] functions available for use with aggregate?

1. There is also "aggregate.zoo" in the "zoo" package. 2. If your question is which functions can be used for the "FUN" argument, you can write your own. For example: > set.seed(1) > tstDF <- data.frame(x=rep(1:4, e=2), + y=rnorm(8)) > aggregate(tstD
