[BioC] Help: convertion from an affymetrix probe to GO id

[Weiwei Shi]

sorry I misread your post, you are asking form probe to GO, here is
the code using hgu133a as an example:

library(hgu133a)
cc <- as.list(hgu133aGO)
t1 <- sapply(cc, function(x) sapply(x, function(y) y[[1]]))
> t1[1:3]
$`208608_s_at`
  GO:0003779   GO:0005509   GO:0005516   GO:0005856   GO:0006936
GO:0016010   GO:0016020
