In douglaswhitaker/GridItemTools: Grid Item Tools

Convert Grid Value to Likert-type Value

Description

Converts a grid cell's position to a score equivalent to a Likert-type scale point.

Usage

grid_to_uni(
  gc,
  rows = 5,
  cols = 5,
  b = (uni.min - uni.max)/16,
  uni.min = 1,
  uni.max = 9,
  rc = FALSE,
  classify_response = FALSE
)

Arguments

gc	integer indicating a grid cell's position as though the grid were a matrix filled by row with sequential integers.
rows, cols	the dimensions of the grid item.
b	a parameter between -1 and 0, default is a value satisfying Audrezet's (2016) six constraints.
uni.min, uni.max	integers specifying the minimum and maximum value for the unidimensional (Likert-type) mapping. Default is a 9-point scale.
rc	logical. If TRUE the function will correct for a reverse-coded grid item.
classify_response	Logical indicating if Positive (P), Negative (N), Indifferent (I), or Ambivalent (A) should be returned instead of a numeric value computed with S(i,j). Default is FALSE.

Value

A number derived from a grid cell's position and transformed to be equivalent to a value on a 9 point Likert-type scale.
