Restoring objects from Excel files

Restores objects from Excel files that have been dumped using xlcDump.

Usage

xlcRestore(file = "dump.xlsx", pos = -1, overwrite = FALSE)

Arguments

file

Excel file from which to restore objects. This is normally a file that has been produced with xlcDump. Defaults to "dump.xlsx".

pos

Environment into which to restore objects. Can be specified either as an integer specifying the position in the search list, as a character naming an element in the search list or as an environment. Defaults to -1 which refers to the current environment.

overwrite

logical specifying if data objects should be overwritten if they already exist inside the environment pos.

Value
