Hi Joshua, SORRY for not making that clear. I wish to have the correlation values between each column of my "file" with the "LGD". For example:
cor (Column 1, LGD) cor (column 2, LGD) ... so on. The first one you have provided is producing an error : > sapply(file[1:47231, 3:10], FUN = cor, y = rep(LGD, 47231), method = "pearson") Error in FUN(X[[1L]], ...) : incompatible dimensions Cheers, Chintanu =============================================== On Mon, Aug 15, 2011 at 12:09 PM, Joshua Wiley <jwiley.ps...@gmail.com>wrote: > Hi Chintanu, > > Do you want the correlation of columns 3:10 of file with the y vector > or do you want a correlation matrix of all variables? > > ## correlation between cols 3:10 and y > sapply(file[1:47231, 3:10], FUN = cor, y = rep(LGD, 47231), method = > "pearson") > > ## correlation matrix > cor(cbind(file[1:47231, 3:10], rep(LGD, 47231)), method = "pearson") > > HTH, > > Josh > > > On Sun, Aug 14, 2011 at 7:02 PM, Chintanu <chint...@gmail.com> wrote: > > Hi, > > > > I am not sure how to fix the following error. > > > > LGD <- c(11.6, 12.3, 15.8, 33.1, 43.5, 51.3, > > 67.3, 84.9) > > > > cor (x=(file [1:47231,3:10]), y= rep (LGD, 47231), method = "pearson") > > > > Error in cor(x = (file[1:47231, 3:10]), y = rep(LGD, 47231), method = > > "pearson") : > > > > incompatible dimensions > > > >> sessionInfo() > > > > R version 2.13.0 (2011-04-13) > > > > Platform: i386-pc-mingw32/i386 (32-bit) > > > > locale: > > > > [1] LC_COLLATE=English_Australia.1252 LC_CTYPE=English_Australia.1252 > > LC_MONETARY=English_Australia.1252 > > LC_NUMERIC=C LC_TIME=English_Australia.1252 > > > > attached base packages: > > > > [1] stats graphics grDevices utils datasets methods base > > > > loaded via a namespace (and not attached): > > > > [1] tools_2.13.0 > > > > Thank you. > > > > Kind regards, > > > > Chintanu > > > > [[alternative HTML version deleted]] > > > > ______________________________________________ > > 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<http://www.r-project.org/posting-guide.html> > > and provide commented, minimal, self-contained, reproducible code. > > > > > > -- > Joshua Wiley > Ph.D. Student, Health Psychology > Programmer Analyst II, ATS Statistical Consulting Group > University of California, Los Angeles > https://joshuawiley.com/ > [[alternative HTML version deleted]] ______________________________________________ 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.
