courseProgressionSGP | R Documentation |
Utility function used to analyze supplied long data or an existing SGP class object to identify potential course progressions suitable for analysis with analyzeSGP
, studentGrowthPercentiles
, etc. See examples for more information.
courseProgressionSGP(
sgp_object,
lag.direction=c("FORWARD", "BACKWARD"),
year)
sgp_object |
Either a panel data set in long form or an object of class SGP. See embedded |
lag.direction |
Character string indicating whether the progressions should be produced prospectively or retrospectively. |
year |
Character indicating the value of YEAR that is the focus of analysis. |
Function returns a nested list
class object. The final node of each nested list is a data.table
which summarizes the number of students with a particular GRADE by CONTENT_AREA by YEAR course progression
