dimCheck: Function to Check the Dimensions of Inputs to longCat

Description

Function for checking the dimensions of y and times and returning a logical indicator indTime of whether individually varying times of observation were detected. Used internally by longCat, though it may be called by the user.

Usage

dimCheck(y, times)

Arguments

y

a data matrix or data frame in wide (as opposed to long) format with cases in rows and repeated observations in columns. At most, y can have 9 unique non-missing values.
