The I() must be there to prev
R still doesn't seem to recognize the data.frame ... I get a [6] ERROR:
object 'depy.w' not found from the following code:
dep <- pls[,1:4]
ind <- pls[,5:8]
eqn <- data.frame(depy = dep, indx = ind)
apls <- plsr(depy.w + depy.h + depy.d + depy.s ~ indx.a + indx.i + indx.r +
indx.x, data=eqn)
Thanks Michael. I had tried to drop the I(as.matrix(...)) conversions, and
fiddled with a number of other permutations of code ... I still can't seem
to get it right.
The col names appear to be depy and indx ... here is the output (and the
rows are just line numbers)
> colnames(eqn)
[1] "dep
The attach(eqn) seems to change some things in the format, but doesn't solve
the problem ... here is my script
> dep <- pls[,1:4]
> ind <- pls[,5:8]
> eqn <- data.frame(depy = dep, indx = ind)
> attach(eqn)
The following object(s) are masked from 'eqn (position 3)':
depy.d, depy.h, depy.
It's nice to cc the list for archival reasons -- it also usually gets
you a faster response as more folks can see how the thread develops.
The problem is that the colnames aren't ctually depy and indx: they
are depy.w, depy.h, etc. If you want to model, you need to use those
as is: e.g., with your
No. Do not do that. While it looks nice at first, it quickly becomes
the source of innumerable errors.

Can you post dput(head(eqn, 30)) so we can take a look at your data?
It's something of a cryptic error and that would go a long way in
helping us help you.
Without that though, I'm not sure you need the I(as.matrix.(dep)) and
I(as.matrix(ind)), I would imagine (untested) that eqn <-
data.frame(dep
I am still/again having trouble getting PLSR to recognize the input data
frames. Here is what I have done:
I read in an 1 x 8 table of data to 'pls'
assign the first four columns to matrix 'dep' and the second four to matrix

ind <- pl
Dear Bjørn-Helge Mevik:
Thank you so much (!!) for your speedy help. This works perfectly, no
fuss. My understanding of data.frames is still fuzzy, so I knew it was
some flaw in my understanding.
I enjoyed your very informative writeups on the package in JSS and R-News;
they told me a lot ab

I have been working with the pls procedure and have problems getting the
procedure to work with matrix or frame data. I suspect the problem lies in
my understanding of frames, but can't find anything in the documentation
that will help.

I read in an 1 x 8 table of
