In crosstable: Crosstables for Descriptive Analyses

Get label if wanted and available, or default (name) otherwise

Description

Get label if wanted and available, or default (name) otherwise

Usage

get_label(x, default = names(x), object = FALSE, simplify = TRUE)

Arguments

x	labelled object. If x is a list/data.frame, get_label() will return the labels of all children recursively
default	value returned if there is no label. Default to names(x).
object	if x is a list/data.frame, object=TRUE will force getting the labels of the object instead of the children
simplify	if x is a list and object=FALSE, simplify the result to a vector

Value

A character vector if simplify==TRUE, a list otherwise

Examples

xx=mtcars2 %>%
  set_label("The mtcars2 dataset", object=TRUE)
xx$cyl=remove_label(xx$cyl)

#vectors
get_label(xx$mpg) #label="Miles/(US) gallon"
get_label(xx$cyl) #default to NULL (since names(xx$cyl)==NULL)
get_label(xx$cyl, default="Default value")

#data.frames
get_label(xx)
get_label(xx, object=TRUE)
data.frame(name=names(xx), label=get_label(xx, default=NA)) #cyl is NA

#lists
get_label(list(xx$cyl, xx$mpg))          #cyl is NA
get_label(list(foo=xx$cyl, bar=xx$mpg))  #default to names
get_label(list(foo=xx$cyl, bar=xx$mpg), default="Default value")
