R help - Mar 2013 - lm and Formula tutorial

Dear all,
I was reading last night the lm and the Formula manual page, and 'I have to
admit that I had tough time to understand their syntax. Is there a simpler guide
for the dummies like me to start with?

I would like to thank you in advance for your help

Regards
Alex

I may be wrong, but I believe what makes it difficult is that the Help
file assumes some linear model statistics that you may not have. I
suggest that you look for a tutorial on linear models first and then
re-read the Help. Incidentally, the provenance of the syntax is GLIM
(correction requested if I'm wrong), and the Nelder-McCullough book on
GLM's has a chapter on linear models and syntax that is relevant,
iirc.
