Selecting Variables
Hi All,
i have a dataset that i want to dynamically inspect for the number of
variables that start with "Exposure_" and then for these count the entries
across each case i.e
ID Exposure_1 Exposure_2 Exposure_3
1 y y y
2 y y -
3 y - -
So the corresponding new variables that would be created are
ID Max_Exposure Unique_Exposure
1 3 3
2 3...
