Hi, I need to do some spatial habitat modeling in grasp (er) and I'm using the Mac OSX version of the R binary (1.14 build 2129) I used the package installer to install the grasper package, but I get a tcltk error when I try to load it. Do I need a tcltk version of R to run this, and If so where can I find this? Thanks Ken PS Here is the error message given when loading grasper Your version of R is up to date Loading required package: mgcv This is mgcv 1.3-13 Loading required package: MASS Loading required package: tcltk Loading Tcl/Tk interface ... Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/tcltk/libs/tcltk.so': dlopen(/Library/Frameworks/R.framework/Resources/library/tcltk/ libs/tcltk.so, 10): Library not loaded: /usr/local/lib/libtcl8.4.dylib Referenced from: /Library/Frameworks/R.framework/Resources/library/ tcltk/libs/tcltk.so Reason: image not found Error: .onLoad failed in 'loadNamespace' for 'tcltk' Error: package 'tcltk' could not be loaded >

Yes, and it is included in the R release disk image (dmg) from CRAN, but it is optional, so you have to choose "custom install" and select it. You can also find the separate "tcltk" installer in the "Packages" directory of the image. Don't forget that this is X11 Tcl/ Tk, so you also have to install Apple's X11 and have it running.
