TextSTATis a concordance program which was designed to be user friendly and provide simple Internet functionality. Texts can be combined to form corpora (which can also be stored as such). The program analyses these text corpora and displays word frequency lists and concordances to search terms. Jun 25, 2018 TextSTAT is text concordance software that runs on both Windows (XP or Vista) and Mac. According to the TextSTAT website the Windows version 'includes everything you need to use TextSTAT with Windows. It comes as a single installation file.' I haven't tested this.
Description
Produces counts and document frequencies summaries of the features in adfm, optionally grouped by a docvars variable or other suppliedgrouping variable.
Usage
Arguments
a dfm object
(optional) integer specifying the top n features to be returned,within group if groups is specified
either: a character vector containing the names of documentvariables to be used for grouping; or a factor or object that can becoerced into a factor equal in length or rows to the number of documents.NA values of the grouping value are dropped.See groups for details.
character string specifying how ties are treated. Seedata.table::frank() for details. Unlike that function,however, the default is 'min', so that frequencies of 10, 10, 11would be ranked 1, 1, 3.
additional arguments passed to dfm_group(). This canbe useful in passing force = TRUE, for instance, if you are grouping adfm that has been weighted.
Value
a data.frame containing the following variables:
feature(character) the feature
frequencycount of the feature
Using Textstat To Use
rankrank of the feature, where 1 indicates the greatestfrequency
docfreqdocument frequency of the feature, as a count (thenumber of documents in which this feature occurred at least once)
docfreqdocument frequency of the feature, as a count
groupUsing Textstat To Find
(only if groups is specified) the label of the group.If the features have been grouped, then all counts, ranks, and documentfrequencies are within group. If groups is not specified, the groupcolumn is omitted from the returned data.frame.
Using Textstat To Print
textstat_frequency returns a data.frame of features andtheir term and document frequencies within groups.
