pSchVec |
A vector of (integer) School IDs; any existing fixed covariate rows in the database where the participant is shown as currently in one of these schools will be included. |
If a participant switches schools (which happens regularly), this function will only pull his/her data if his/her *current* school is in the input vector.
A dataframe that has the same format as the database table 'PInf.dbo.SMaster'. Column names fairly accurately describe column contents, but one should consult the qq codebook for precise definition.
