(Apologies if this arrives twice. I first sent it from a gmail account.) Hello All, Another noob question. Assume I have function foo(): foo <- function(a,b) { *does some stuff...* *creates a matrix J creates a scalar k *list(J,k) } If you run this function, then foo(aye,bee) will return something like this: [[1]] [,1] [,2] [1,] .5 .2 [2,] .4 .3 [[2]] [,1] [1,] .8 Let us assume that you want to reference the [1,1]th element of J. If the function ONLY returned that matrix, then the syntax is the following: bar <- foo(aye,bee)[1,1] So far, so good. I cannot figure out how to call that same element when the function returns two things, though. None of the following work: baz <- foo(aye,bee)[1,1] baz <- J.foo(aye,bee)[1,1] baz <- foo.J(aye,bee)[1,1] baz <- foo(aye,bee)[1[1,1]] baz <- foo(aye,bee)[1,1,1] baz <- foo(aye,bee)[J:1,1] Does anyone know what the RIGHT syntax is?
