For a text or a collection of texts (in a quanteda corpus object), return a list of a keyword supplied by the user in its immediate context, identifying the source text and the word index number within the source text. (Not the line number, since the text may or may not be segmented using end-of-line delimiters.)
kwic_old(x, keywords, window = 5, valuetype = c("glob", "regex", "fixed"), case_insensitive = TRUE, ..., new = FALSE)
keywords
will be tokenized using the ...
options."glob"
for
"glob"-style wildcard expressions; "regex"
for regular expressions;
or "fixed"
for exact matching. See valuetype for details.TRUE
FALSE
for this functionA kwic object classed data.frame, with the document name

), the token index position (position
), the context
before (contextPre
), the keyword in its original format
(keyword
, preserving case and attached punctuation), and the context
after (contextPost
).
