I don't know if I will be able to help solve your problem, but failure to
follow the recommendations in the Posting Guide was probably getting you off in
the wrong foot when you posted on the other (more appropriate?) mailing list,
as it is here.
A) Code is garbled. Post using plain text format... this is a setting you have
to choose in your email program.
B) Code is not reproducible. We cannot run your code to get your error due to
missing library statements and no data. The Posting Guide and Google have
suggestions for how you can make your example reproducible.
C) Assuming you are using the PCNM package, the documentation found by Google
(which you can probably read using ?quickPCNM) says quickPCNM expects a matrix,
but it looks like you are giving it a data frame. Read your introductory R
training materials (e.g. the Introduction to R document that ships with R) to
understand the distinction. But I have never used this function so this could
be a red herring.
Please go read the Posting Guide.
