Dear People, I have been trying to perform concatenation operations on lists without success. Consider the following example.
x <- runif(2) y <- runif(2) z <- runif(2) xy <- list(x,y) xyz <- list(x,y,z)
I want to have a function foo such that foo(xy,z) is the same as xyz. This appears not to be as easy as I thought, though there must be a way.
Maybe this can give you a starting point. I guess their are more elegant ways to do this ...
clist <- function (liste, x) {
+
+ tmp <- paste("list(",
+ paste(paste("liste[[",1:length(liste),"]]",sep=""),
+ collapse=","),",x)",sep="")
+ eval(parse(text=tmp))
+ }
clist(xy,z)
