lm() of one matrix against another
Hello R list,
I have two matrices of identical dimensions, and I want to fit a
straight line for each pair of columns and plot the resulting lines.
I got it to work with a for loop, but there must be a better way,
> n<-5
> N<-10
>
> data.x<-matrix(1:(n*N),ncol=n)
> data.y<-matrix(1:(n*N) + rnorm(n*N,sd=1),ncol=n)
