I am trying to learn R, and am having problems with doing a simple linear
regression.  I loaded data from a fixed width file, using wd=c(...), and
read.fwf(...) and I can read in the file ok and it comes in as vectors in
columns, which is what I expected.  The problem is when I try to do a linear
regression, lm=(y~x), I get the following error message, "Error in
model.frame.default(formula = y ~ x, drop.unused.levels = TRUE) : 

  invalid type (list) for variable 'y'

 

I tried various things, such as wd=numeric(c(..)), unlist(y) and putting x
and y in a data frame and attaching it, but nothing helps.  I have searched
through 3 online manuals, but can't seem to find an answer.  Maybe this is
so simple that nobody felt the need to address it.  

 

Thanks for your help.
