catDiffs2: Differences in Categorical Variables
In guytuori/simScores: Similarity Scores for Baseball Players

Description Usage Arguments Value Examples

Computes the scaled difference between a vector of categorical variables and a matrix of categorical variables. Should not usually be called by hand. Instead, use the calcScores2 function.

1	catDiffs2(vec, dat)

`vec`	a character vector. Each value in the vector corresponds to a unique variable.
`dat`	a character matrix or data.frame of character variables. The number of columns must be equal to the length of `vec`.

a matrix of the same dimensions as dat. The ith entry in the jth row is 0 if the jth value of vec is equal to the jth value of the ith row of dat. It is 1 if they are different. If either the ith value of the jth row of dat or the jth value of vec are missing, and NA will be returned.

example_vec <- c("a", "b", NA)
example_dat <- matrix(c("a", "a", "a",
                        "b", "b", "b",
                        NA, "b", "a"),
                      nrow = 3, byrow = T)
catDiffs2(example_vec, example_dat)
