util_observations_in_subgroups {dataquieR} | R Documentation |
This function uses !is.na
to count the number of non-missing observations in subgroups of
the data (list) and in a set of user defined response variables. In some applications it is
required that the number of observations per e.g. factor level is higher than a user-defined
minimum number.
