randIndFx | R Documentation |
randIndFx
calculates distance of categorical data (as Rand Index, Adjusted Rand Index or Jaccard Index).
Note: uses/requires package flexclust
Methods so far available (via flexclust): "ARI" .. adjusted Rand Index, "RI" .. Rand index, "J" .. Jaccard, "FM" .. Fowlkes-Mallows.
randIndFx(ma, method = "ARI", adjSense = TRUE, silent = FALSE, callFrom = NULL)
ma |
(matrix) main input for distance calulation |
method |
(character) name of distance method (eg "ARI","RI","J","FM") |
adjSense |
(logical) allows introducing correlation/anticorrelation (interprete neg distance results as anti) |
silent |
(logical) suppres messages |
callFrom |
(character) allow easier tracking of messages produced |
This function returns a distance matrix
