I seem to be having problems with the value of .Dyn.libs being saved between sessions. The value is being assigned in library.dynam by assign(".Dyn.libs", c(.Dyn.libs, name), envir = .GlobalEnv) I don't know enough about R environments to decide if this means it will be saved between sessions if the workspace is saved and restored. If so, this should be changed because you do not want to restore previous values of this variable in a new session. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
