congruence.array: Congruence coefficients for a 3-way array
In friendly/tableplot: Represents tables as semi-graphic displays

Description Usage Arguments Value Author(s) See Also Examples

Calculates congruence coefficients (or some other statistic) for the rows and columns of a three-way array over the last dimension (layers) of the array.

Typically, each layer of the array gives factor or component loadings for a different sample or rotation.

1	congruence.array(X, FUN = congruence.coef, stat.name = "phi", round = FALSE, scale = 1, ref = "last")

`X`	A three-dimensional array
`FUN`	A function of two vector arguments, returning a single number
`stat.name`	Name for the statistic calculated
`round`	If `TRUE`, round the `scale`ed array to the nearest integer. If numeric, the the `scale`ed array is rounded to the given number of decimal places.
`scale`	Multiplier for the array returned
`ref`	Reference (baseline) level of the third dimension of `X`

An array with one more row and column than X and the same number of layers, containing the calculated statistic in the last row and column.

NEO.sm <- transpose(NEO[1:12,,])
congruence.array(NEO.sm, scale=100, round=TRUE)

congruence.array(NEO.sm, FUN=function(a,b) max(abs(a-b)), stat.name="max.diff", round=2)
