Fellow Expressionists,
I want to output the object that I created containing
my normalized data points for further processing with
by either Excel or SAS (I am very much a beginner in R).
I have encountered the following dificulty:
> write.table(swirl,"")
Error in as.data.frame.default(x[[i]], optional = TRUE) :
can't coerce marrayRaw into a data.frame
> ls()
[1] "last.warning" "RGcol" "swirl" "swirl.norm"
"swirl.norm1"
[6] "swirl.norm2" "swirl.normm" "swirl.norms" "tmp"
>
(The "" is just for illustration. I get the same error message
when I output to a file, of course.)
Also, when I try write.matrix, I get,
> write.matrix(swirl.norm,"")
Error: couldn't find function "write.matrix"
>
I would appreciate any suggestions as to how I can output the
normalized intensities. I regret bothering the group with
somethin so elementary. I have read the relevant parts of
"An Introduction to R", and R Data Import/Export, "The Basics
of S-Plus" and the on-line help for the write, write.table,
and write.matrix commands. I would expecially appreciate it,
if in addition to any specific suggestions, you could something
that I could read that deals with this topic.
Thanks and best wishes,
Rich
