POSACupdate: Update POSAC output objects given new X and Y (perhaps from...
In CambridgeAssessmentResearch/POSAC: Partial order scalogram analysis

This function takes the output from the function POSAC along with new vectors of X and Y co-ordinates and updates the object to reflect the change.

1	POSACupdate(posacout, newX, newY)

`posacout`	Output from function POSAC (or something with similar parts).
`newX`	Vector of new values for the X co-ordinates (will be converted to ranks).
`newY`	Vector of new values for the Y co-ordinates (will be converted to ranks).

The function returns a list with the following elements:

Criteria: The output from the function realcriteria for the new solution.
X: The ranking of each pattern on the first dimension of the returned POSAC solution.
Y: The ranking of each pattern on the second dimension of the returned POSAC solution.
Patterns: A character vector of concatenated patterns.
patmat: The pattern matrix used in analysis to begin with.
freqs: The frequency with which in pattern occurs.
tidyframe: A single data frame containing the structuples(patterns), frequencies, X, Y, rescaled X and Y to be between a 0 and 100, J (=rescaled X+rescaled Y)and L(=100+rescaled X-rescaled Y).
mumatrix: Matrix of monotonicity coefficients between each of the original variables and the resulting rescaled X, Y, J and L.
