Hi,
> R\rw1090\library\marrayInput\data, there are 7 files whose name is
In the marrayInput.pdf document in
R\rw1090\library\marrayInput\doc\ the command:
data(swirl)
loads the swirl.RData file EARLY in the document, but this may
be confusing because you WILL NOT have an .RData file BEFORE
you start your microarray analysis. You have the option of
saving your R session to an .RData file AFTER you have done some
analysis.
So just ignore the data(swirl) command in marrayInput.pdf
for now (and ignore the following line showing the contents of
the swirl object within R).
You could also look at the limma package which demonstrates
methods of reading two-color array data (including the swirl
data set). In limma you would use read.maimages(...) instead of
read.marrayRaw(...).
The marrayInput package and marrayClasses, marrayNorm etc.
have now been merged into one package, just called marray. So
if you have a package called marrayInput, it may be out of date.
Hope this helps,
James
