Rename Polling Firms

Merges polling firms that are published under different names. Spellings that only differ in case, accents, punctuation and white space (such as "INSA/YouGov" and "INSA YouGov") are merged by popRead() already; this function is for everything that needs knowledge about the firms, e.g. a firm that has been renamed or polls published under the name of a partner.

Usage

popRenameFirms(x, firms)

Arguments

x

A popPolls object.

firms

Named character vector: the names are the firm names to replace, the values the names to use instead, e.g. c("Peter Hajek" = "Hajek"). The names are matched ignoring case, accents, punctuation and white space.

Value

x with the firm column of $polls renamed. The names as published are kept in the firmRaw column.

Details

Renamings that should apply to every popRead() can be set once with options(pollofpolls.firms = c(...)). Renamings are not chained: with c(A = "B", B = "C") firm A becomes B, not C.

Examples

if (FALSE) { # \dontrun{
at = popRead('AT-parliament')
popFirms(at)
at = popRenameFirms(at, c('Peter Hajek' = 'Hajek', 'Market' = 'Market/Lazarsfeld'))

# for all polls read from now on
options(pollofpolls.firms = c('Peter Hajek' = 'Hajek'))
} # }
