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.
Examples
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)
