[R] step

[Diana Schwegler]

Hello I am using the "step" function in order to do backward selection for a
linear model of more than 200 variables but it doesn't work correctly.
I think, there is a problem, if the matrix has same or more columns than
rows. 
And if the matrix has too much columns the step-function doesn't work
because the function will work with all columns together and I think, this
is
the problem.
Is there a solution or a bug fixing of this problem?

Thanks a lot
