Hi all, Im very new to R and Bioconductor so please forgive my poor language! I've been trying to ma on my list of probeIDs the relative annotation but unsuccessfully. I get this error The object "probes" is a data.frame so maybe a should change its class? How would i do that? Thanks a lot -- output of sessionInfo(): symbols <- mget(probes,mouse4302SYMBOL,ifnotfound=NA) > Error in .checkKeysAreWellFormed(keys) : > keys must be supplied in a character vector with no NAs -- Sent via the guest posting facility at bioconductor.org.

If you are unsure what to do, you might try posting the result of head(probes) sapply(probes, class) and tell us which column you are interested in.
