Hello List
I'm moving this over from the bioC list as, although the problem I'm working on is biological, the current bottle neck is my poor understanding of R.
I wonder if someone would help me with the following function.
cumulMetric <- function(deMirPresGenes, deMirs){
???
#need to match position of each miR in deMirPresGenes with its FC to form a vector of FC in correct order
? ? fc <- deMirs
? ? fcVector <- as.numeric(with (fc, FC[match(deMirPresGenes[,4], Probe)] ) )
? ? #multiply fc by context score for each in...

[BioC] problem with function
...;- cbind(deMirPresGenes[,2], metric)
? ? colnames(geneMetric) <- c('sym', 'metric')

? ? #make cumul by aggregate
? ? listMetric <- aggregate(as.numeric(geneMetric[,2]), list(geneMetric[,1]), sum)#returns a dataframe
??? colnames(listMetric) <- c('symbol','cumulMetric')
? ?
??? #return whole list

}
