...I think the column value of the hist plot should correspond to x$counts/sum(x$counts) (x=hist(samples,breaks=50,probability=TRUE)). The size of data is a little bit larger, causing failure of uploading. If you need the data, I can email it to you. Can anyone help me? Thanks!

Hi all mailing listers, I wanna get the last several elments of vector. e.g. x <- c(1,2,3,.....,78, 79, 80) How can I implement to assign last three elements to y, y <- c(78, 79, 80) ? In Matlab, It can easily achieve by y=x(end-2:end) Thanks Huaping Wan [[alternative HTML version deleted]]

I need to repeat a function many times, with differing parameters held constant across iterations. To accomplish this, I would like to create a list (or vector) of parameters, and then insert that list into the function. For example: q<-("l,a,b,s") genericfunction<-function(q){ } ###### The equivalent code would of course be genericfunction<-function(l,a,b,s){ } Any help

...ing. I want to remove the packageA from the working window after using the packageA so as not to causing problem. I do not want to carry out task each time using packageA and packageB individually because many the tasks share many parameters. Any ideals and suggestion will be much appreciated.

Dear R mailing listers, After plotting, I wanna save it as file in pdf format using pdf("name.pdf") command. It failed, but I can do it by GUI operation (file-save as-pdf). e.g. x11() hist(x, breaks = 50, probability = FALSE) pdf("hist.pdf") [[alternative HTML version deleted]]
