Read a response patterns file
Description
Read a set of response patterns from a file. The file formats are described in the kstIO-package information page.
Usage
read_kdata(filename, format = "auto", as.letters = TRUE)
Arguments
filename |
A character string specifying the name of the data file. |
format |
Specification of the files format. Can be "SRBT", "KST", "matrix", "CSV", or "auto" (default). |
as.letters |
logical, should the elements of the sets be letters or numbers? |
Details
The format values "SRBT", "KST", and
"matrix" refer to the different generations of file formats
described in kstIO-package. The value "auto" (default)
requests an automatic detection of the format by thje read_XXX
function.
If as.letters is TRUE the elements of the sets are letters,
otherwise numbers.
Value
A binary matrix with the response patterns.
Note
In automatic format detection, the distinction between "matrix"
and "KST" formats work somewhat heuristic. In other words, in rare
cases the automatic detection might give the wrong result.
