[SOLVED] Asterisks in the output of R describe function

Asterisks in the output of R describe function

What does it mean the asterisk next to some item names in the descriptive statistics table given by describe function (package psych) in R ?

                       vars  n    mean    sd 
STUDY_ID*                 1 67    1.00  0.00
COUNTRY_ID*               2 67    1.00  0.00

RANDOMIZATION_R1*        11 66    1.50  0.50

Thank you

Solution

From ?psych::describe:

If the check option is TRUE, variables that are categorical or logical are converted to numeric and then described. These variables are marked with an * in the row name.
