I would like to be able to double click on an R source file and by that start R and have the file sourced in R. I am using WinXP Pro. So I created an association for file type R and tye following Run action: "C:\Program Files\R\rw1090beta\bin\Rgui.exe" R_PROFILE=%1 I have an R file with the following lines at the beginning. library(vcd) votes<-array(0,10*7*9*2) dim(votes)<-c(10,7,9,2) Double clicking this file (in Windows Explorer) starts R and then produces the following output. Attaching package 'vcd': The following object(s) are masked from package:base : print.summary.table summary.table Error in dim(votes) <- c(10, 7, 9, 2) : cannot do complex assignments in base namespace So it seems the first 2 lines are executed, the vector votes exists, but cannot be redimensioned as an array. Can i make what I would like fully functional? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-38624 Fax: +43-1-4277-9386
