You misquoted that line. There is no function before the (

The general approach in R is often called "whole object". That is,
you try to put your data into a structure that will facilitate the
operations you wish to perform. In this case bind the responses into
a matrix and use matplot
matplot(x, cbind(foo1, foo2, foo3), type = 'p')
