Hello! I was working on this annotation function for GDS4523
and I used the following function but it came as error
annotation(eset) <- "HG-U133_Plus_2"
package ‘HG-U133_Plus_2.db’ is not available (for R version 3.2.2)
Error in library(HG - U133_Plus_2.db) : 'package' must be of length 1
So i don't know how to fix this as I need to finish the gene filtering before monday, it would be great if anyone can help me solving this
