Plotting Functions for 'profile' Objects

plot and pairs methods for objects of class "profile", but renamed as vplot and vpairs.

vplot.profile(x, ...)
vpairs.profile(x, colours = 2:3, ...)

Arguments

x

an object inheriting from class "profile".

colours

Colours to be used for the mean curves conditional on x and y respectively.

...

arguments passed to or from other methods.

Details

See profile.glm for details.

Author

T. W. Yee adapted this function from profile.glm, written originally by D. M. Bates and W. N. Venables. (For S in 1996.)

Examples

pneumo <- transform(pneumo, let = log(exposure.time))
fit1 <- vglm(cbind(normal, mild, severe) ~ let, acat,
             trace = TRUE, data = pneumo)
#> Iteration 1: deviance = 5.407271
#> Iteration 2: deviance = 5.34745
#> Iteration 3: deviance = 5.347382
#> Iteration 4: deviance = 5.347382
pfit1 <- profile(fit1, trace = FALSE)
if (FALSE) { # \dontrun{
vplot.profile(pfit1)
vpairs.profile(pfit1)
} # }
