I am working with microarray analysis and was using PAM with excel interface. Is
there a way to do random divisions for the training set in excel?
I also tried PAM in R with the pamr menu. How can I do the random divisions in
R?
Then I tried to reproduce "classification with gene expression data",
which is chapter 24 from the book "bioinformatics and computational biology
solutions using R and Bioconductor". There is also an explanation for
random divisions using "eset" as an example. How do I have to load my
data into R, to be able to reproduce, what they have done? what kind of file is
eset? is it like an excel spreadsheet? I have my microarray data now in a .csv
or .txt file with phenotype in the first row, class in the second row and then
gene expression data starting from the third row. first column are the affy-IDs.
I have two classes.
I would appreciate it, if someone could help me out with that!!!
