Using functions and environments
- by Eduardo Leoni
Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example:
y <- new.env()
with(y, x <- 1)
f <- function(env,z) {
with(env, x+z)
}
f(y,z=1)
throws
Error in eval(expr, envir, enclos) : object 'z' not found
I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).
