grade.set: Grade Sets

In grade: Binary Grading functions for R.

Description

Checks a the set (vector in R) studentans against correctans. grade.orderedset enforces order, grade.set does not.

Usage

grade.set(correctans, studentans, tolerance=0.01, useeval=TRUE,
          usena=FALSE, useinf=FALSE, quiet=TRUE)
grade.orderedset(correctans, studentans, tolerance=0.01, useeval=TRUE, 
                 usena=FALSE, useinf=FALSE, quiet=TRUE)

Arguments

correctans	a vector of type numeric or a string
studentans	a vector of type numeric or a string
tolerance	a string or numeric representing the accepted component wise tolerance
useeval	TRUE or FALSE indicates whether or not to use 'eval' on strings
usena	TRUE or FALSE indicating whether or not NA is an accepted value
useinf	TRUE or FALSE indicating whether or not Inf and -Inf are accepted values
quiet	TRUE or FALSE. If TRUE there are more warning messages when checks fail. Can be helpful for debugging.

Value

TRUE if the sets match. FALSE otherwise.

Note

The grade main page contains a discussion of the common parameters correctans, studentans, useeval, usena, useinf, quiet.

Examples

grade.set(c(1,2), "[1,2]") # TRUE
grade.orderedset(c(1,2), "[1,2]") # TRUE

grade.set(c(2,1), "[1,2]") # TRUE
grade.orderedset(c(2,1), "[1,2]") # FALSE

grade.set(c(1,2), "[1.1,2]", tolerance=".01") # FALSE

grade.set(c(1,2,3,4,5), "(5,4,3,2,1)") # TRUE
grade.set(c(1,2,3,4,5), "(5,4,3,2)") # FALSE

grade.orderedset("[NA, 1, 2]", c(NA, 1, 2)) #FALSE, usena=F
grade.orderedset("[NA, 1, 2]", c(NA, 1, 2), quiet=FALSE) # FALSE, but with warning
grade.orderedset("[NA, 1, 2]", c(NA, 1, 2), usena=TRUE) # TRUE
