 Thanks for the replies to my prior question.  My problem is that R always
says object not found when I enter a variable name into a command.  I
converted a Stata file into an Rdata file by first loading the foreign
package by entering

require(foreign)

Then I asked R to read the Stata file by entering

pol572a1<- read.dta("C:\\alex\\Graduate Coursework\\Pol 572\\pol572a1.dta")

So now I can do a few things with the data, but I am only able to do so by
entering

with(pol572a1,

before typing another command. So I enter the following for a scatter plot:
with(pol572a1, plot(rgnpc, incmean))

When I run a simple linear regression, I enter the following: with(pol572a1,
lm(incmean~rgnpc))

But when try to get a fitted line, I enter the following: with(pol572a1, lm(
share.gnp)<-lm(incmean~rgnpc))  But I get the following error message: Error
in lm(share.gnp) <- lm(incmean ~ rgnpc) : object "share.gnp" not found

So what should I do to get R to read the dataframe in the ordinary way with
the usual command?  I am willing to scrap this dataframe and use the
original Stata file to start over, as long as that resolves the problem.

Thanks!

Alex
