meta_system: Internal function to get, set or initialize system metadata

Description

Sets or initializes system metadata for new objects.

Usage

meta_system(x, field = NULL)

meta_system(x, field = NULL) <- value

# S3 method for corpus meta_system(x, field = NULL) <- value

# S3 method for tokens meta_system(x, field = NULL) <- value

# S3 method for dfm meta_system(x, field = NULL) <- value

# S3 method for dictionary meta_system(x, field = NULL) <- value

meta_system_defaults()

Value

meta_system returns a list with the object's system metadata. It is literally a wrapper to meta(x, field, type = "system")().

meta_system<- returns the object with the system metadata modified. This is an internal function and not designed for users!

meta_system_defaults returns a list of default system values, with the user setting the "source" value. This should be used to set initial system meta information.

Arguments

x

an object for which the metadata will be read or set

field

metadata field name(s); if NULL (default), return all metadata names

value

new value of the metadata field

Examples

Run this code
corp <- corpus(c(d1 = "one two three", d2 = "two three four"))
# quanteda:::`meta_system<-`(corp, value = quanteda:::meta_system_defaults("example"))
quanteda:::meta_system(corp)
