It is generally less error prone to avoid attach (even once).
dat
lm.1<-lm(ve~ su)

And instead use:

lm.1<-lm(ve~ su, data=dat)

summary(lm.1)

Dear friends,
I have a csv file entitled ven.csv located in C:\\, this file  
contains only
two columns:"ve" and "su" I have written the following lines:
data=read.csv("c:\\ven.csv",header=TRUE,sep=";");

lm(ve~ su)
I have obtained the following message:

Error in eval(expr, envir, enclos) : object 've' does not exist.  
What's the
problem? thank you for your help in advance
