Recode Variables with Regular Expression

Recode variables with regular expression based on the specification in tbl_KodeBok with TYPE RE. The specification in the codebook can be specific, common or general. Specific is when both LESID and FILGRUPPE are specified to create a unique reference to be able to recode the variables. Common is when only FILGRUPPE is specified while LESID left empty and general is when FILGRUPPE is specified with ALLE while LESID left empty.

do_recode_regexp(dt = NULL, spec = NULL, con = NULL)

Arguments
