Greetings, R-help!
On 2 Fedora Core 2 Linux systems, i've completely erased the previous R and all packages and then installed R-2.0 and installed fresh packages.
In using Rcmdr, I see some trouble and I wonder if other people see this and if it is due to the tcl/tk, or R, or Rcmdr. (If readers have not yet tried Rcmdr, I recommend it not just because of the GUI it provides, but also because Prof. Fox has created several very handy commands, like scatter3d, which make it possible to use advanced packages like rgl. Rcmdr provides several very handy wrapper commands that "just work" and users don't have to fuss over so many details! And, if you are new at R, you can use pull down menus and then Rcmdr displays the commands that correspond with those menu options. Very educational!)
In no particular order, here are the issues I see with R-2.0 and Rcmdr
1. In the panel to select a dataset from a package (nenu: Data/Data in packages), I can type in the name of a dataset, but the GUI will not let me choose the name of a package from which to select a dataset. Nothing happens when I pick a package name. (With previous R/Rcmdr, I did not have this trouble).
2. When using Rcmdr, some of the output from commands shows in the Rcmdr bottom window, but some is sent to the xterm in which R was started. For example, with a scatter3d() command, if I add the option model.summary=T, the model summary shows in the xterm. But some other models show results in the bottom pane of Rcmdr. And, it seems to me, there are some commands in which I've noticed some of the output going to the Rcmdr bottom buffer and some to the xterm.
3. When I want to exit Rcmdr and choose the pull down "exit from Commander and R", I get a Segmentation Fault that closes Rcmdr and R.
4. 3d plots do not display on the screen until I click in the rgl window that displays the graph. This might be a video card/AGP driver problem, I suppose. These systems have the NVidia FX5200 cards and the NVidia proprietary X driver. If other users don't see the same on other kinds of systems, I guess that will tell me where the problem lies.
5. At random times, I get an error tcl/tk window popping up with a message about MASS and categorical variables. It says
Error in data(package=parse(text=packageName)); 'MASS' must be character string or NULL
It says that over and over, sometimes it has other package names, as in:
Error in data(package=parse(text=packageName)); 'relimp' must be character string or NULL
These seem to be harmless? -- Paul E. Johnson email: [EMAIL PROTECTED] Dept. of Political Science http://lark.cc.ku.edu/~pauljohn 1541 Lilac Lane, Rm 504 University of Kansas Office: (785) 864-9086 Lawrence, Kansas 66044-3177 FAX: (785) 864-5700
