In jknowles/ModelEWS: Wisconsin Dropout Early Warning System

Description

Convert dataset to a model matrix suitable for training in caret

Usage

gatherData(grade, conn, DV = "grad_ind", na.omit = TRUE)

Arguments

grade	a numeric representing the grade level to extract data for
conn	a connection object suitable for extracting data
DV	a character representing the variable name of the dependent variable
na.omit	logical, should rows with an NA be omitted, default is TRUE

Details

First the function extracts data from buildTrainingPool, then it builds a model matrix out of the formula DV ~ ., first excluding all "KEY" variables which represent year, school, district, and student identifiers. Then it returns the model matrix.

Note

Using na.omit=FALSE may result in a non-conformable array due to a mismatch between the DV vector length and data vector length. This function has not been modified to allow this yet.
