In krisrs1128/mvarVis: Visualize multivariate analysis results.

Usage

running_cosines(coord)

Arguments

coord

The coordinates from which to compute contributions. We assume coordinates for all dimensions are present.

Value

The sum of squared cosines up to each dimension, for each observation.

Examples

data(wine)
wine_mfa <- ordi(wine[, -c(1:2)], "MFA", wine[, 1:2], group = c(5,3,10,9,2), type = rep("s",5), graph = F)
coord <- slot(slot(wine_mfa, "table")$ind, "coord")
