Not everyone carefully examines the code from r-help posts
prior to pasting it in. Posting code is very dangerous and
should not be done.
Quite the contrary they often try to understand the
code by running it.
Code like this should never be posted.

please don't use if you don't know what you are using.

I just quickly draft one with boston housing data. and it should be
close to what you need.
# REMOVE ALL OBJECTS
rm(list = ls());
# DATA PREPARATION
library(MASS);
data(Boston);
X<-I(as.matrix(Boston[-14]));
Y<-I(as.matrix(Boston[14]));
for(i in 1:13)
{
X2 <- X[, i]
data <- data.frame(Y, X
Dear R community,
I have a dataframe with say 100 different variables. I wish to regress
variable 1 separately on every other variable (2-100) in a linear regression
using lm. There must be an easy way to do this without loops, but I have
difficulties figuring this out... Can you please help?
