make_newdata: Creates a 'newdata' list to modify the plots for specific individual profiles (with respect to the covariates)

Description

Creates a 'newdata' list to modify the plots for specific individual profiles (with respect to the covariates)

Usage

make_newdata(data, vars, conts = NULL)

Value

newdata

The list 'newdata' to be passed as optional argument to a call to the 'plot' method

labs

A vector of labels (say to use in the plot, for each profile)

Arguments

data

The original dataset that has been used as input to the call to 'fit.models'

vars

A vector of strings, including the names of the variables that are to be used to construct specific profiles of individual covariates

conts

A subset of 'vars', which include the named covariates that are continuous. These will be averaged over, while for the remaining covariates (assumed to be factors), the specific profiles will be listed. Defaults to NULL

Examples

if (FALSE) {
data(bc)

# Fits a model using the 'bc' data
mle = fit.models(formula=Surv(recyrs,censrec)~group,data=bc,
    distr="exp",method="mle")
# Now makes the default plot
plot(mle)
# Now creates a 'newdata' list to modify the plot for selected profiles
newdata=make_newdata(data=bc,vars="group")
# And can plot, say, only two of the three treatment arms
plot(mle,newdata=newdata$newdata[c(1,3)],lab.profile=newdata$labs[c(1,3)])
}
