default quanteda_options when namespace not loaded

[mpadge]

Finally enjoying getting to use the package for initial flipper explorations, but discovered that quanteda_options is used throughout, yet is not recognised when the full namespace is not loaded.

pkgs <- tools::CRAN_package_db()
pkg_txt <- apply (cbind (pkgs$Title, pkgs$Description), 1, paste, collapse = " ")
pkg_corpus <- quanteda::corpus (pkg_txt)
pkg_dfm <- quanteda::dfm (pkg_corpus, remove = stopwords ("english"), stem = TRUE,
      remove_punct = TRUE)
## Error in if (verbose) catm("Creating a dfm from a corpus ...\n") :
## argument is of length zero

The quick and dirty solution would be to include an extra

if (is.null (verbose))
   verbose = FALSE

in ... every function.

@mpadge great to have you using quanteda and filing issues!

On this options/namespace issue, I'd suspected that this would be the case, and I think the solution will be to insert a call to

quanteda_initialize()

which will initialize at default values any options not already set. @koheiw could do this today or I will tonight or tomorrow.

Fixed now in the master branch, but: You will still need to use

pkg_dfm <- quanteda::dfm(pkg_corpus, remove = quanteda::stopwords("english"), stem = TRUE,
                         remove_punct = TRUE)

since stopwords() is a quanteda function.
