pvalue.ellipse {pda} | R Documentation |
This is used by int.plot
to construct ellipses for means at the
level of the x factor that are not significantly different.
Currently this does not handle mixed models properly.
pvalue.ellipse(plet, lsmeans, se, rdf, level=0.05, scale=0.3, full.width=TRUE, pset)
plet |
character vector with letter codes for non-significant differences |
lsmeans |
least squares means |
se |
standard errors for means |
rdf |
residual degrees of freedom |
level |
significance level |
scale |
scaling of ellipse around means |
full.width |
keep ellipses as full width to show how close means are if TRUE |
pset |
letters to use for means that are significantly different |
The ellipse will be the height of an LSD comparison interval if
full.width
is TRUE, or otherwise will be se*scale
beyond
the outer means of a comparison group.
A 2*n
matrix, where n
is the number of distinct
ellipses. The first row contains ellipse centers while the second row
contains the radii.
