errors with partition_bundle from context-objects

[mxi-hug]

I'm not entirely sure, what the internal problem is here, but the partition_bundle-method on context-objects returns a strange partition_bundle-object. As a result, all functions applied to the new pb-object fail (merge(), features(), as.DocumentTermMatrix()).

First hint at the problem: str(pb_a) returns the warning

Warnung in str.default(obj, ...)
'str.default': 'le' is NA, also als 0 betrachtet

Minimal Example

cont_a <- context("GERMAPARL", query = 'Teilzeitzwangsgesetz', cqp = F)

... getting corpus positions
... number of hits: 1
... checking that all p-attributes are available
... getting token id for p-attribute: word
... generating contexts
... counting tokens

pb_a <- partition_bundle(cont_a)

|++++++++++++++++++++++++++++++++++++++++++++++++++| 100% elapsed = 00s
Warnung in str.default(obj, ...)
'str.default': 'le' is NA, so taken as 0

pb_a <- enrich(pb_a, p_attribute = "word", progress = TRUE)

|++++++++++++++++++++++++++++++++++++++++++++++++++| 100% elapsed = 00s
Warnung in str.default(obj, ...)
'str.default': 'le' is NA, so taken as 0

dtm <- polmineR::as.DocumentTermMatrix(pb_a, col = "count")

... using the p_attribute-slot of the first object in the bundle as p_attribute: word
... generating (temporary) key column
... generating cumulated data.table
... getting unique keys
... generating integer keys
Fehler in simple_triplet_matrix(i = unname(i), j = DT[["j"]], v = DT[[col]], :
'i, j' invalid

(And yes, i'm aware that a context, let alone a partition-bundle on a single hit is rather useless. I just wanted to exclude overlapping windows etc as a source for the error)

Dear Max,

there are two kinds of issues we have (had) here: The first warning arises from missing sizes in the partition objects that are generated. That's fixed. The second one is that generating a TermDocumentMatrix requires names of the partitions in a partition_bundle to be present. The solution I chose now is to assign (increasing) integer numbers as names to the objects in a partition_bundle, if not present.

Should work now, with the next push to the dev branch.

Kind regards
Andreas
