R help - Sep 2003 - coef names in lm

Dear all,
I am interested in finding out how to change the names of coefficients in
the lm function. I have a design matrix which I called "design" where
each
variate has its own name. However when I issue the command:

lm.1<-lm(response~design-1, weights=some.weights)

and follow it with:

summary(lm.1)

it seems to paste as a character the names of the variates
with design i.e I have something like:

designAge
designPlace
designOccupation
...
as names of coefficients and instead I just wanted to be
it seems to do
Age
Place
Occupation.

P.S.. the reason I need this is because I am using the xtable library to
turn output into latex tables and do not want to manually delete each and
every single "design" word in the coefficients name vector.

Thank you so much for any feedback,

Jean Eid

If you coerce "design" into a data frame and then do

lm.1 <- lm(response ~ . - 1, data=design, ...)

that should work.

Maybe this will work for you:

df <- as.data.frame(design)
lm.2 <- lm(response ~ ., df)
