[R] how to do regression analysis for multiple dependent variables at once

[Hiroto Miyoshi]

Dear R-users

I have, say, 5 dependent variables, d1 to d5.
And I also have 2 independent variable x1, x2.
Suppose I need to do regression analyses for all
the dependent variables, using the same set 
of independent variables, x1 and x2.

How can I do the analyses without writing five lines of
lm(d1~x1*x2)
lm(d2~x1*x2)
lm(d3~x1*x2)
lm(d4~x1*x2)
lm(d5~x1*x2)

I like to write the R codes something like
l <- c("d1","d2","d3","d4","d5")
for( i in l ) lm(i~x1*x2).

However, this does not work.

I hope you get the idea about what I want to do.
So, Could you help me.
Sincerely
