Dear All,

I was using GEOquery package
After doing required steps
I did this

probesets <- Table(GPLList(gse6901)[[1]])$ID
> data.matrix <- log2(do.call("cbind", lapply(GSMList(gse6901), function(x)
{
+ tab <- Table(x)
+ mymatch <- match(probesets, tab$ID_REF)
+ return(tab$VALUE[mymatch])
+ })))

Error in log(c("27", "59.8", "34.1", "110.5", "130.3", "569.3", "210.5",  :
  Non-numeric argument to mathematical function

Can u please help me solving this error as I am not able to understad what
that error means

I shall be very thankful for ur kind help
