you can just use a design matrix on the right hand side of 'formula', e.g.,
factors <- matrix(rnorm(100*10), 100, 10)
y <- rnorm(100)
lm(y ~ factors)
I hope it helps.

Hello,
How could I generalize the following statement for an arbitrary number of
columns instead of 7?
result[[i]]<-lm( returns[,i] ~ factors[,1] + factors[,2] + factors[,3] +
factors[,4] + factors[,5] + factors[,6] + factors[,7] )
Thank you,
