Thank you for the reply. That format works but since I need access to x, y subsequent to lm() also, I tried the following but now I'm back to the same old error message of "object y not being found".
data_model.df = read.table("./verify.txt", header=TRUE, nrows=10); dd = datadist(data_model.df); options(datadist = 'dd'); describe(data_model.df); f <- lm(y ~ x) print( summary(f) ) plot(x, y) I tried without "options" and "describe" and still the same problem.
