To whom it may concern My name is Kenta Suzuki. Today I subscribed the R-help. I do not know about this R-help in detail but I send this e-mail since I have some trouble on programming R. When I type help() in general id dose not work properly. For instance, when I type, help("plot") in R, it shows; Error in file(out, "wt") : cannot open the connection on the Internet. Beside the problem, when I try to install packages like rgl, it always shows; Warning in install.packages("rgl") : 'lib = "C:/Program Files/R/R-3.1.2/library"' is not writable Error in install.packages("rgl") : unable to create ?C:\Users\<U+5065><U+592A>\Documents/R/win-library/3.1? In addition: Warning message: In dir.create(userdir, recursive = TRUE) : cannot create dir 'C:\Users\<U+5065><U+592A>', reason 'Invalid argument' How can I fix these problems? I would be great if you give me the solutions. Yours Sincerely, Kenta Suzuki [[alternative HTML version deleted]]
