size(x, ...)
# S4 method for character
size(x, s_attribute = NULL, verbose = TRUE, ...)
# S4 method for partition
size(x, s_attribute = NULL, ...)
# S4 method for DocumentTermMatrix
size(x)

Arguments

x

object to get size(s) for

...

further arguments

s_attribute

character vector with s-attributes (one or more)

verbose

logical, whether to print messages

Value

an integer vector if s_attribute is NULL, a data.table otherweise

Details

One or more s-attributes can be provided to get the dispersion of tokens across one or more dimensions. Two or more s-attributes can lead to reasonable results only if the corpus XML is flat.

# NOT RUN {
use("polmineR")
size("GERMAPARLMINI")
size("GERMAPARLMINI", s_attribute = "date")
size("GERMAPARLMINI", s_attribute = c("date", "party"))

P <- partition("GERMAPARLMINI", date = "2009-11-11")
size(P, s_attribute = "speaker")
size(P, s_attribute = "party")
size(P, s_attribute = c("speaker", "party"))
