First, install the corresponding affimatrix chip name:
source("
http://bioconductor.org/biocLite.R")
biocLite("hu35ksuba")
second, upload the package from R
third, read the your desired transfer:
x <- hu35ksubaUNIGENE
# Get the probe identifiers that are mapped to an UNIGENE ID
mapped_probes <- mappedkeys(x)
# Convert to a list
xx <- as.list(x[mapped_probes])
if(length(xx) > 0) {
# Get the UNIGENE for the first five probes
xx[1:5]
# Get the first one
xx
1
}
last, write into file:
dput(xx,'aaaaa')
