"unknown timezone" error

If you are getting error like “unknown timezone ‘default/America/Toronto’.”, the following workaround would fix it.

  1. Open or create .Rprofile file under your home directory.
  2. In the .RProfile, add the following line. (Replace “America/Toronto” with your timezone. The list of valid timezone names are listed here.)
Sys.setenv(TZ = "America/Toronto")

After that, restart Exploratory and the error should not appear anymore.

This is a known R bug, and will be fixed in R3.4.3, which Exploratory will be using in the next release. After that, this issue will not happen even without this workaround.
