eeptools is an R package that seeks to make it easier
for analysts at state and local education agencies to analyze and
visualize their data on student, school, and district performance. By
putting simple wrappers around a number of R functions,
eeptools strives to make many common tasks simpler and less
prone to error specific to analysis of education data.
eeptools provides three new datasets of interest to
education researchers. These datasets are also used in the R Bootcamp for Education
Analysts

in school average assessment scores. It contains observed and predicted
values of aggregated test scores at the school level for a large
midwestern state.
For analysts using unit-record data of some type, there are several
calc functions which automate common tasks including
calculating ages (age_calc), grade retention
(retained_calc), and student mobility
(moves_calc).
age_calc(dob = as.Date('1995-01-15'), enddate = as.Date('2003-02-16'),
units = "years")
#> [1] 8.087671
age_calc(dob = as.Date('1995-01-15'), enddate = as.Date('2003-02-16'),
units = "months")
#> [1] 97.03571
age_calc(dob = as.Date('1995-01-15'), enddate = as.Date('2003-02-16'),
units = "days")
#> Time difference of 2954 daysage_calc also now properly accounts for leap years and
leap seconds by default.
retained_calc takes a vector of student identifiers and
a vector of grades and checks whether or not the student was retained in
the grade level specified by the user. It returns a data.frame of all
students who could have been retained and a yes or no indicator of
whether they were retained.
x <- data.frame(sid = c(101, 101, 102, 103, 103, 103, 104, 105, 105, 106, 106),
grade = c(9, 10, 9, 9, 9, 10, 10, 8, 9, 7, 7))
retained_calc(df = x, sid = "sid", grade = "grade", grade_val = 9)
#> sid retained
#> 1 101 N
#> 2 102 N
#> 3 103 Y
#> 4 105 Nretained_calc is intended to be used after you have
processed your data as it does not take into account time or sequence
other than the order in which the data is passed to it.
moves_calc is intended to identify based on enrollment
dates whether a student experienced a school move within a school
year.
df <- data.frame(sid = c(rep(1,3), rep(2,4), 3, rep(4,2)),
schid = c(1, 2, 2, 2, 3, 1, 1, 1, 3, 1),
enroll_date = as.Date(c('2004-08-26',

manipulation easier. One thing users of other statistical packaegs may
miss when using R is a convenient function for determining the
mode of a vector. The statamode function is
designed to do just that. statamode works with numeric,
character, and factor data types. It also includes various options for
how to deal with a tie demonstrated below.
vecA <- c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
statamode(vecA, method = "stata")
#> [1] "."
vecB <- c(1, 1, 1, 3:10)
statamode(vecB, method = "last")
#> [1] 1
vecC <- c(1, 1, 1, NA, NA, 5:10)
statamode(vecC, method = "last")
#> [1] 1
vecA <- c(LETTERS[1:10]); vecA <- factor(vecA)
statamode(vecA, method = "last")
#> [1] J
#> Levels: J
vecB <- c("A", "A", "A", LETTERS[3:10]); vecB <- factor(vecB)
statamode(vecB, method = "last")
#> [1] A
#> Levels: A
vecA <- c(LETTERS[1:10])
statamode(vecA, method = "sample")
#> [1] "J"
vecB <- c("A", "A", "A", LETTERS[3:10])
statamode(vecB, method = "stata")
#> [1] "A"
vecC <- c("A", "A", "A", NA, NA, LETTERS[5:10])
statamode(vecC, method = "stata")
#> [1] "A"There are a number of functions to save you keystrokes like
defac for converting a factor to a character,
makenum for turning a factor variable into a numeric
variable, max_mis for taking the maximum of a vector of
numerics and ignoring any NAs (useful for inclusion in
do.call or apply constructions).
remove_char allows you to quickly gsub out a
specific character from a string vector such as an * or
.... decomma is a somewhat specialized version
of this for processing data where numerics are written with commas.
nth_max allows you to identify the 2nd, 3rd, etc. maximum
value in a vector.
eeptools includes ways to simplify the use of regression
analyses tools recommended by Gelman and Hill 2006 through the
gelmansim function, which itself is a wrapper for the
arm::sim() function.
