Description
Frequently asked questions for the ctmm package.Details
General recommendations:
- Do not save workspaces between sessions. They can become corrupted.
- Upgrade
R to the latest version and update all of your packages.
- Work through the vignettes
vignette("variogram") and vignette("akde").
- Check the http://www2.physics.umd.edu/~hfleming/ to see if there is a beta release that fixes any bugs.
- Check the https://groups.google.com/forum/#!forum/ctmm-user.
Specific issues:
- Database corruption, missing functions, and other weird errors
R likely did not install the package correctly. I.e., some files may have failed to overwrite previous versions. Uninstall ctmm, restart R, and install ctmm again.manipulate::isAvailable is not found- You probably have an outdated copy of the
manipulate package installed. Update R to the latest version and then update all of your packages. This seems to happen frequently with the MacOS release of R.
- The
manipulate panel does not popup in variogram.fit or zoom - Click the gear icon in the upper-left corner of the plot window.
- There is no save button in
variogram.fit - Maximize the plot window and/or increase your screen resolution.
plot complains about the datatype or has weird errors- Namespace collision sometimes occurs from
raster or sp against move and ctmm. Restart R and only load the ctmm package.
- Infinite recursion error
ctmm has no recursive functions, so I am not exactly sure what causes this error, but it only occurs with certain versions of R on certain computer architectures. There are several solutions that have worked for people, including restarting R in a fresh session and updating their software. Alternatively:
- Reboot your computer.
- Increase the allowed number of nested expressions within
R via options(expressions=10000) or some other large number.
- Try a different computer.
