Calculate estimated likelihoodprofiles.
Description
This function calculates loglikelihood profiles for the selected variables. Despite the function name, these are not true profile likelihoods as they hold all other coefficients fixed at their MLE.

## Note: This example assumes a boolean model has already been fit.
## Display the contours of the likelihood given a change the value of
## the coefficients.
(prof < boolprof(fit))
## Extract the plots for x1_a and x4_b.
plot(prof, y = c("x1_a", "x4_b"))
plot(prof, y = c(1, 3), scales = list(y = list(relation = "free")))
## You can also use variable or index matching with boolprof to select
## particular covariates of interest.
boolprof(fit, vars = c(1, 3))
boolprof(fit, vars = c("x1_a", "x4_b"))
## End(Not run)
