Hi,
really I hope this is not a stupid question. I would like to write a text
file with the output of pamr.confusion function. Obviously I tried first
with the usual
>write.table(file="test.txt",pamr.confusion(mysamplespamtrain, thr))
K N Class Error rate
K 26 4 0.1333333
N 2 23 0.0800000
Overall error rate= 0.109
but all I write is an empty file. The same with "write" or assigning
pamr.confusion to a variable (pc <- pamr.confusion(.....) ).
I also tried changing the device, to write a jpeg or whatelse; I tried to
play with Device related commands. No way. I followed James McDonald
suggestion
found in the mail archive.
>pamr.confusion(mData.results, threshold=4.0)
(table)
>savePlot("Confusion", "wmf")
Error in savePlot("Confusion", "wmf") : no such device (...well, there's no
graph device...).
Anyway, there's anyone who has some hints ? I think that maybe is a simple
command, but I don't know how to do it.
Thanks in advance, and sorry if is a too banal question...
Giulio
