[BioC] problem with function
...e efficient as well.
Thanks for the help offered.
My function now looks like this (for the record!) and behaves as it should.
makeMetric <- function(deMirPresGenes, deMirs){
???
#need to match position of each miR in deMirPresGenes with its FC to form a vector of FC in correct order
???
??? fcVector <- as.numeric(with (deMirs, FC[match(deMirPresGenes[,4], Probe)] ) )
??? #multiply fc by context score for each interaction???
? ? metric <- fcVector * as.numeric(deMirPresGenes[,11])
? ? geneMetric <- cbind(deMirPresGenes[,2], metric)
? ? colnames(geneMetric) <- c('sym', ...

help with function
...rent 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 interaction
? ? metric <- fcVector * as.numeric(deMirPresGenes[,11])
? ? geneMetric <- cbind(deMirPresGenes[,2], as.numeric(metric))
? ? #make cumul weighted score
? ? listMetric &...
