simint.reverse

From HH v1.5
0th

Percentile

Force all comparisons in a "hmtest" from simint to have the same sign.

Force all comparisons in a "hmtest" from simint to have the same sign. If the contrast "A-B" has a negative estimate, reverse it show the contrast "B-A" with a positive estimate,

Usage
simint.reverse(y, estimate.sign = 1, ...)    ## Rmulticomp.reverse(y, estimate.sign = 1, ...) ## S-Plus
Arguments
y
"simint" object
estimate.sign
If estimate.sign==1, reverse the negatives. If estimate.sign==-1, reverse the positives. Both the names of the comparisons and the numerical values are reversed. If estimate.sign==0, return the argument.
...
other arguments not used.
Value

• The result is a "simint" object containing the same contrasts as the argument but with the sign of the contrasts changed as needed.

Note

S-Plus use the multicomp functions and R uses the multcomp package.
