cohort_rit_trace_plot(mapvizieR_obj, studentids, measurementscale,
  match_method = "no matching", first_and_spring_only = TRUE,
  entry_grade_seasons = c(-0.8, 4.2), collapse_schools = TRUE,
  retention_strategy = "collapse", small_n_cutoff = -1)

Arguments

mapvizieR_obj

conforming mapvizieR obj

studentids

vector of studentids

measurementscale

target subject

match_method

do we limit to matched students, and if so, how? no matching = any student record in the studentids. UNIMPLEMENTED METHODS / TODO strict = only kids who appear in all terms strict after imputation = impute first, then use stritc method back one = look back one test term, and only include kids who can be matched

first_and_spring_only

show all terms, or only entry & spring? default is TRUE.

entry_grade_seasons

which grade_level_seasons are entry grades?

collapse_schools

treats all students as part of the same 'school' for purposes of plotting, so that one trajectory is shown. default is TRUE. if FALSE will separate lines by school and show a lengend.

retention_strategy

c('collapse', 'filter_small') retained students show up as cohorts of 1 student. collapse will run 'collapse_by_grade' to merge those students into existing cohorts. 'filter_small' will drop them from this visualization.

small_n_cutoff

numeric, drop observations that are smaller than X cohort maximum.

Value

a ggplot2 object
