Check and set behaviour for lost tags

Source: R/lost_tags_action.R
lost_tags_action.Rd

This function determines the behaviour to adopt when tagged variables of a linelist are lost e.g. through subsetting. This is achieved using options defined for the linelist package. The function can be used in isolation, but it can also accept a dataset as first argument, so that it can be used in pipelines as well.

Usage

lost_tags_action(action = c("warning", "error", "none"), quiet = FALSE, x)

get_lost_tags_action()

Arguments

action

a character indicating the behaviour to adopt when tagged variables have been lost: "error" (default) will issue an error; "warning" will issue a warning; "none" will do nothing

quiet

a logical indicating if a message should be displayed; only used outside pipelines

x

deprecated

Value

returns NULL; the option itself is set in options("linelist")
