Print a matrix of pair-wise comparisons based on an 'sma' fit.

multcompmatrix(smfit, sort = TRUE)

Arguments

• smfit: An object of class 'sma', fit with sma.
• sort: Logical. Specifies whether or not to sort groups from smallest to largest value based on the parameter of interest (slope, elevation or mean fitted value).
