Display image in tcl/tk information window: path to file ?
Dear Ulrike, If I understand correctly what you want to do, the image file is stored in your package. If so, you can use the .path.package() function to locate your package on the file system. For example, the Rcmdr uses the following code to find its etc subdirectory: file.path(.path.package(package="Rcmdr")[1], "etc"). I hope this helps, John ------------------------------ John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox

image,
if the user presses a button. Everything works fine with the command
tcl("image", "create", "photo", "MaxC2.image", file="MaxC2res3image.gif")
for image creation, as long as the file entry refers to the correct
location
of the file on my hard drive. How can I make this portable ? I currently have the image stored in the inst directory. "R CMD INSTALL --build" moves it to the top directory in the zip file. I have no idea how to tell R (or tcl) where to look for the file. Any help is appreciated! Best regards, Ulrike ************* Ulrike Groemping BHT Berlin -- View this message in context:
