split_portion {textshape} | R Documentation |
Some visualizations and algorithms require text to be broken into chunks of
ordered words. split_portion
breaks text, optionally by grouping
variables, into equal chunks. The chunk size can be specified by giving
number of words to be in each chunk or the number of chunks.
split_portion(
text.var,
grouping.var = NULL,
n.words,
n.chunks,
as.string = TRUE,
rm.unequal = FALSE,
as.table = TRUE,
