smc {scrime} | R Documentation |
Computes the values of (or the distance based on) the simple matching coefficient or Cohen's Kappa, respectively, for each pair of rows of a matrix.
smc(x, dist = FALSE) cohen(x, dist = FALSE)
x |
a matrix consisting of integers between 1 and n.cat,
where n.cat is the number of levels the variables in x
can take. Missing values are allowed. |
dist |
should the distance based on the simple matching coefficient or Cohen's Kappa, respectively,
be computed? Note that, e.g., smc(x, dist = TRUE) is equal to 1 - smc(x, dist = FALSE) . |
A matrix with nrow(x)
columns and rows containing the distances or similarities.
