# S3 method for class 'px'
px_description(x, value, validate = TRUE)

Arguments

x

value

Optional. A character string to set the value for all languages or a data frame with columns 'language' and 'value' to set it for specific languages. If 'value' is missing, the current DESCRIPTION is returned. If NULL, DESCRIPTION is removed.

validate
