In almartin82/MAP-visuals: KIPP MAP Visuals

Description

term_split2 returns a data frame splitting a TermName

Usage

term_split2(term_name, grade = NULL)

Arguments

term_name	character vector of term names from NWEA CDF.
grade	(optional, default = NULL) integer vector of grade levels

Details

This function returns a data framre with length(x) rows that separates a TermName character vector into the following components (here we use "Spring 2012-2013" as en example element of the vector:

• Season ("Spring"),

• Year1 (2012),

• Year2 (2013),

• SY (i.e School Year, "2013-2014").

In addition, if a length(x) vector of grade levels is passed to the optional second argument then an additional column will be added to the data frame:

• CohortYear (HS graduation year based on grade and year2, so an 7th grader in spring 2013 would be in the class of 2018).

Value

a data frame of with length(x) rows and 4 (5 if grade vector supplied) columns

Examples

x<-c("Spring 2012-2013",
"Fall 2013-2014",
     "Winter 2012-2013",
     "Fall 2012-2013" ,
     "Spring 2013-2014")

grades<-c(3:7)
term_split2(term_name=x,
            grade=grades )
