Hi Nick,
Thanks for your reaction.
readLines("28370.xls") gives the following output:
> readLines("28370.xls")
Error in file(con, "r") : unable to open connection
Since I started R from "/Applications/R" (I'm using a Mac) and the
file is on "~/Desktop" this is what I would assume. Using the full
path works fine:
> readLines("~/Desktop/28370.xls")
[1] "!Exptid=28370"
[2] "!Experiment Name=hyperinsulinemic clamp in human muscle"
[3] "!Organism=Homo sapiens"
.....lots of lines....
For your information: I am using R V2.01, latest Bioconductor (updated
yesterday) and marray V1.5.25 (latest development packages; stable
package gives the same problem).
Any idea?
Kind regards,
Rene
