Hi, I guess this is pretty basic. I have 25 variables in the data file (name: score), i.e. X1,X2,.....,X25. I dont want to use score$X1, score$X2 everytime I use these variables. Is there a way I can rename all these variables as simply X1,X2,.....X25 without writing 25 lines of code, one line for renaming each variable (eg: > X1=score.X1 >X2=score.X2 and so on) ? Thanks for your help. Regards, Preetam -- Preetam Pal (+91)-9432212774 M-Stat 2nd Year, Room No. N-114 Statistics Division, C.V.Raman Hall Indian Statistical Institute, B.H.O.S. Kolkata.

You haven't said yet, what object your 'data file' is. If you mean a
data.frame I would use colnames(dataName) <- c("Col1Name",
"col2Name", ?.)

Depending on what your doing perhaps with() could help? Or assuming a data.frame or matrix, score[ , 25] will give you Score$X25 If you would supply a bit more information (and code) about what you are doing we probably can help more.
