Hello! I got something to ask..whether you can help me with the R program...i got this for example 5x4 matrix..and i want to find: i) mean for each row of the matrix ii) median for each column of the matrix and i need to do this using a loop function...below is my program..u try to check it for me as the output that i got is not what i desired...thanks..
data<-rnorm(20,0,1) dim(data)<-c(5,4) is.matrix(data) data a<-function(x) { for(i in 1:nrow(x)) { for(j in 1:ncol(x)) { med<-median(x[,j]) mean<-mean(x[i,]) print(c(med=med,mean=mean)) } } } a(data) Chris Guure Researcher Institute for Mathematical Research UPM ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
