Description Usage Arguments Details Value References Examples

The function computes the congruence index according to Joerin Fux (2005).

1	con_n3_holland(a, b)

`a`	a character vector with person Holland codes.
`b`	a character vector with environment Holland codes.

The function finds the congruence according to Joerin Fux (2005) between the up to six-letter Holland-codes given in argument a, which is the person code, and argument b, which is the environment code. The Index as defined by Jörin (2005) targets (only) three letters from the Holland code. The degree of congruence is output, according to its definition by Joerin Fux (2005), as a reciprocal value of a distance. This means, for example, that a value of '3' is the result for a perfect fit of two three-letter codes !

a numeric with value for congruence.
