Well, your data does not match up with what arun used.  You have space delimited variable names and no spaces between  any of the numbers.  If the number should be broken up like arun has comma separated, then it is even easier.  I stored the following data in a file, temp.txt,

X1 X2 X3
age race stat
12 2 35
17 6 55

and read it like this


dat1<- read.table("c:/tmp/temp.txt", header=TRUE, skip=1)

and got this 

> dat1
  age race stat
1  12    2   35
2  17    6   55

Hope this is helpful,
