emmGrid
objectsThese functions provide methods for rbind
and
[
that may be used to combine emmGrid
objects
together, or to extract a subset of cases. The primary reason for
doing this would be to obtain multiplicity-adjusted results for smaller
or larger families of tests or confidence intervals.
## S3 method for class 'emmGrid' rbind(..., deparse.level = 1, adjust = "bonferroni") ## S3 method for class 'emmGrid' e1 + e2 ## S3 method for class 'emmGrid' x[i, adjust, drop.levels = TRUE, ...]

A revised object opf class emmGrid
The result of e1 + e2
is the same as rbind(e1, e2)
rbind
throws an error if there are incompatibilities in
the objects' coefficients, covariance structures, etc. But they
are allowed to have different factors; a missing level '.'
is added to factors as needed.
warp.lm <- lm(breaks ~ wool * tension, data = warpbreaks) warp.rg <- ref_grid(warp.lm) # Show only 3 of the 6 cases summary(warp.rg[c(2,4,5)]) # Do all pairwise comparisons within rows or within columns, # all considered as one faily of tests: w.t <- pairs(emmeans(warp.rg, ~ wool | tension)) t.w <- pairs(emmeans(warp.rg, ~ tension | wool)) rbind(w.t, t.w, adjust = "mvt") update(w.t + t.w, adjust = "fdr") ## same as abve except for adjustment
