Row wise function call.
I have another issue.i have a function which calculates the log2(col i /col2) value, where i stands for columns 3,4,...etc. data<-read.table("table.txt", header=TRUE) iratio<-function(x){ for(n in 3:ncol(data)){ z<-log2(data[x,n]/data[x,2]) } } Where x- the row number of the data frame(data). i want to store the ratios for each row in a object z, which can be accessed outside the function. How can i do this? Thanks, Vasu. [[alternative HTML version deleted]...
