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

Description

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, ...)    ## R
multicomp.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.
