Sir I am very new user of R language. I have a problem. I have imported data on R console and then i used "save workspace" option to save data. Is it right way to save data. Then to read data in extremes toolkit using saved workspace I got the following messages Package extRemes: For a tutorial and more information go to http://www.esig.ucar.edu/extremevalues/evtk.html [1] "Successfully opened file: lahore" X... N NA mean NA Std.Dev. NA min NA Q1 NA median NA Q3 NA max NA missing values NA Saving workspace (may take a few moments for large workspaces) ... Workspace saved. Sir I request you to please guide to me in very simple way. Thank You -- AMINA SHAHZADI Department of Statistics GC University Lahore, Pakistan.
