Usage

rproject_bags(sack_of_bags, weighting_table)

Arguments

sack_of_bags

Sack of bag of words

weighting_table

Examples

# NOT RUN {
data(RLdata500)
data.500 <- RLdata500[-c(2,4)]
sack <- sacks_of_bags_of_words(data.500[1:3,c(-2)],k=2)
idf <- calc_idf(sack)
match(names(sack[[1]]), names(idf))
rproject_bags(sack, idf)
# }
