The lib_replace function replaces a data frame
in an existing data library. The function will replace the data
in the library list, the data in the workspace (if loaded),
and immediately write the new data to the library
directory location. The data will be written in the file format
associated with the library engine.
lib_replace(x, ..., name = NULL)The library to replace data in.
The data frame(s) to replace. If you wish to replace more than one data set, separate with commas.
The reference name to use for the data. By default, the name will be the variable name. To assign a name different from the variable name, assign a quoted name to this parameter. If more than one data set is being replaced, assign a vector of quoted names.
