as(<dgTMatrix>, "dgCMatrix") is deprecated

[EmilHvitfeldt]

Hello @dselivanov 👋 I found this deprecation warning, and it didn't have its own issue so I opened one for you

library(text2vec)

it <- itoken(letters)
vectorizer <- hash_vectorizer()
dtm <- create_dtm(it, vectorizer)
#> as(<dgTMatrix>, "dgCMatrix") is deprecated since Matrix 1.5-0; do as(., "CsparseMatrix") instead
