problem with read.table
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.
Thanks again!

same directory as the script file) but
when I run this I get "Error in eval(expr, envir, enclos) : object
"y" not found".
data_model.df = read.table("./verify.txt",
header=TRUE, nrows=10);
f <- lm(y ~ x) Could someone pls tell me what's wrong with this
code?
Sincere thanks!
I don't think there is a problem with read.table(). You need to attach the dataframe or specify data=data_model.df in the call to lm() f <- lm(y ~ x, data = data_model.df) Hope this is helpful, Dan Daniel J.
