Josef,
One easy way is to use "read.table" to create a data frame. For
example, if you have an ASCII file of the following format:
subject,sex,height,weight,age
001,M,183,72,53
002,F,167,55,28
...
called "people.dat" you can create a data frame object with the
command
people.df<-read.table("people.dat",header=T,sep=",")
see read.table in the help pages.
