Print a matrix of pair-wise comparisons based on an 'sma' fit.
A matrix of comparisons is drawn, based on the P values of the pair-wise tests between levels of the grouping variable. An 'X' indicates P < 0.05, 'o' indicates 0.05 < P < 0.1.
multcompmatrix(smfit, sort = TRUE)An object of class 'sma', fit with sma.
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).
Invisibly returns the (character) matrix.
# Print the matrix of comparisons:
data(leaflife)
sm1 <- sma(lma ~ longev + site, data=leaflife, multcomp=TRUE)
multcompmatrix(sm1)
#> Multiple comparison matrix.
#> Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

#> site_2
#> site_1 1 3 2 4
#> 1 - *** * ***
#> 3 *** - ***
#> 2 * *** - *
#> 4 *** * -
# Write the matrix to a file like this:

capture.output(multcompmatrix(sm1), file="sm1matrix.txt")
