HI A.k, I need one more question, if you can answer it please M <- matrix(sample(1:8000),nrow=100) colnames(M)<- paste("Col",1:ncol(M),sep="")apply(M,2,function(x) c(Min=min(x),"1st Qu" =quantile(x, 0.25,names=FALSE),Range = range(x), Median = quantile(x, 0.5, names=FALSE), Mean= mean(x),Std=sd(x), "3rd Qu" = quantile(x,0.75,names=FALSE), IQR=IQR(x),Max = max(x)))why I get two range . isn't range mean the different between the max and min
If you want the "span" (what you are calling the range) of the range (min and max) you can do this:
myRange = diff(range(x)) -- David
