)x |
a list of character vectors, dictionary or collocations object |
types |
token types against which patterns are matched |
valuetype |
the type of pattern matching: |
case_insensitive |
logical; if |
concatenator |
the concatenation character that join multi-word
expression in |
levels |
integers specifying the levels of entries in a hierarchical
dictionary that will be applied. The top level is 1, and subsequent levels
describe lower nesting levels. Values may be combined, even if these
levels are not contiguous, e.g. |
remove_unigram |
if |
keep_nomatch |
keep patterns that did not match |
a list of integer vectors containing indices of matched types
