In the RDocumentation of prof. Revelle (psych v1.9.12.31) 'std.err' is mentioned as an argument, and std.err = FALSE 'deprecated', but I cannot obtain the StError wenn I insert it in a call. My data: a 2 x 2 table. Error Message: std.err unused.

I look forward to getting some help.

With many thanks in advance,

Toni
