finding most highly transcribed genes - ranking, sorting and subsets?
...missed
a straight forward way to do this, or a valuable function, but I've been
using my own methods and going around in circles.
So far I've normalized within and between arrays, then returned the RG
values using RG<-RG.MA, then I ranked each R and G values for each array as
below.
rankRG<-RG
rankRG$R[,1]<-rank(rankRG$R[,1])
rankRG$R[,2]<-rank(rankRG$R[,2]) .. and so on for 6 columns(ie. arrays, as
well as the G's)
then I thought I could pull out a subset of rankRG using something like;
topRG<-rankRG
topRG$R<-subset(topRG$R,topRG$R[,1]<500&topRG$R[,...
