tCorpus-cash-feats_to_columns

Cast the "feats" column in UDpipe tokens to columns

Description

If the UDpipe parser is used in create_tcorpus, the 'feats' column contains strings with features (e.g, Number=Sing|PronType=Dem). To work with these nested features it is more convenient to cast them to columns.

Arguments

`keep`	Optionally, the names of features to keep
`drop`	Optionally, the names of features to drop
`rm_column`	If TRUE (default), remove the original column

Details

Usage:

## R6 method for class tCorpus. Use as tc$method (where tc is a tCorpus object).

feats_to_columns(keep=NULL, drop=NULL, rm_column=TRUE)

Examples

if (interactive()) {
tc = create_tcorpus('This is a test Bobby.', udpipe_model='english-ewt')
tc$feats_to_columns()
tc$tokens

tc = create_tcorpus('This is a test Bobby.', udpipe_model='english-ewt')
tc$feats_to_columns(keep = c('Gender','Tense','Person'))
tc$tokens
}
