Xyplot, Densityplot, and Pairs plot methods for a mixedeffects model profile.
xyplot()
draws “zeta diagrams”, also visualizing
confidence intervals and their asymmetry.
densityplot()
draws the profile densities.
splom()
draws profile pairs plots. Contours are for the
marginal twodimensional regions (i.e. using df = 2).
## S3 method for class 'thpr'
xyplot(x, data = NULL,
levels = sqrt(qchisq(pmax.int(0, pmin.int(1, conf)), df = 1)),
conf = c(50, 80, 90, 95, 99)/100,
absVal = FALSE, scales=NULL,
which = 1:nptot, ...)
## S3 method for class 'thpr'
densityplot(x, data, npts = 201, upper = 0.999, ...)
## S3 method for class 'thpr'
splom(x, data,

conf = c(50, 80, 90, 95, 99)/100, which = 1:nptot,
draw.lower = TRUE, draw.upper = TRUE, ...)
x 
a mixedeffects profile, i.e., of class 
data 
unused  only for compatibility with generic. 
npts 
the number of points to use for the 
upper 
a number in 
levels 
the contour levels to be shown; usually
derived from 
conf 
numeric vector of confidence levels to be shown as contours. 
absVal 
logical indicating if 
scales 
plotting options to be passed to 
which 
integer or character vector indicating which parameters
to profile: default is all parameters (see

draw.lower 
(logical) draw lowertriangle (zeta scale) panels? 
draw.upper 
(logical) draw uppertriangle (standard dev/cor scale) panels? 
...

a density plot, a "trellis"
object (lattice package)
which when print()
ed produces plots on the current
graphic device.
