R help - May 2008 - dividing the data

hello,

I have data of individuals; with their age and other infromation. Each row
corresponds to a single individual. I would like to divide the data and
store them into two files. one file with people less than 50 years of age
and the other with people more than 50 years of age. I am new into R and I
appreciate if someone can help.

thanks

Assuming you have your data in a dataframe  x with one column called
"age" (get the data into R e.g. with read.csv)

young <- x[x$age < 50,]

write.table(young,file="young.txt")

etc.
