purpose of .RDataTmp temporary file? [R] -

-

what purpose of r temporary file created in every directory workspace saved? data contain , safe delete?

that file holding file save.image() while r waits file argument succeed. help(save.image) , safe argument -

safe - logical. if true, temporary file used creating saved workspace. temporary file renamed file if save succeeds. preserves existing workspace file if save fails, @ cost of using disk space during save.

so file contains entire workspace image , best leave there in case r fails save workspace normally.

i'm guessing if see file, r has failed rename file may want search file , check contents before deleting temporary file.
