General Statistics for a Character Vector

This function gives general statistics for a character vector, e.g., obtained by loading a text file with the readLines or stri_read_lines function, where each text line' is represented by a separate string.

Usage

stri_stats_general(str)

Arguments

str

character vector to be aggregated

Value

Returns an integer vector with the following named elements:

1. Lines - number of lines (number of non-missing strings in the vector);

2. LinesNEmpty - number of lines with at least one non-WHITE_SPACE character;

3. Chars - total number of Unicode code points detected;

4. CharsNWhite - number of Unicode code points that are not WHITE_SPACEs;

5. ... (Other stuff that may appear in future releases of stringi).

Details

None of the strings may contain \r or \n characters, otherwise you will get at error.

Below by `white space` we mean the Unicode binary property WHITE_SPACE, see stringi-search-charclass.
