invert: Invert the direction of coordinates
In soc.ca: Specific Correspondence Analysis for the Social Sciences

Description Usage Arguments Details Value See Also Examples

Invert one or more axes of a correspondence analysis. The principal coordinates of the analysis are multiplied by -1.

1	invert(x, dim = 1)

`x`	is a soc.ca object
`dim`	is the dimensions to be inverted

This is a convieniency function as you would have to modify coord.mod, coord.ind and coord.sup in the soc.ca object.

a soc.ca object with inverted coordinates on the specified dimensions

soc.mca, add.to.label

example(soc.ca)
inverted.result  <- invert(result, 1:2)
result$coord.ind[1, 1:2]
inverted.result$coord.ind[1, 1:2]
