(Why don't we have examples in there??)
Specifically, you do something like
x <- read.table("myfile.txt")
names(x) <- c("age", "height", "weight")
or, preferably, add a 1st row containing the variable names to the
data file and do
x <- read.table("myfile.txt", header=TRUE)
There's a number of fine points concerning missing value specification
and variable types, for which the help page should be consulted.
