roster_to_growth_df: roster_to_growth_df

In almartin82/mapvizieR: Visualization and Data Analysis tools for NWEA MAP student data

roster_to_growth_df

Description

when you need to put a roster object onto a growth data frame. growth data frames are tricky, because they cover a time *span*, not a single point in time. if a student changes school / grade / teacher (common) or if any of the other demographic attributes of a student change (IEP status / lunch status / gender / etc.) you need to have a consistent rule for attribution. roster_to_growth_df implements that.

Usage

roster_to_growth_df(target_df, mapvizieR_obj, roster_cols,
  join_by = "end", disambiguation_method = "last",
  by_measurementscale = FALSE)

Arguments

target_df	the df you want to put stuff on
mapvizieR_obj	a conforming mapvizieR object
roster_cols	roster column names you want to move over.
join_by	c('start', 'end', 'both')
disambiguation_method	how to disambiguate? default is 'last'.
by_measurementscale	boolean, when you have student demographics that are specific to a particular assessment - eg course enrollment, but the match is specific to student AND measurementscale, not just student. if TRUE your roster object must contain a field called measurementscale.

Value

a growth data frame with the roster objects
