I don't think there is a package to do that.
But you could have a look at ?predict.crr.

Dear R users
I would like to calculate the Cumulative incidence for an event
adjusting for competing risks and adjusting for covariates. One way to
do this in R is to use the cmprsk package, function crr. This uses the
Fine & Gray regression model. However, a simpler and more classical
approach would be to implement the Kalbfleisch & Prentice method (1980,
p 169), where one fits cause specific cox models for the event of
interest and each type of competing risk, and then calculates incidence
based on the overall survival. I believe that this is what the cuminc
function in the aforementioned package does, but it does not allow to
adjust for a vector of covariates.
My question is, is there an R package that implements the Kalbfleisch &
Prentice method for competing risks with covariates?
for example, if k1 is the cause of interest among k competing causes:
P_k1(t; x)=P(T<=t, cause=k1|x)=Sum(u=0, ..., u=t) {hazard_k(u;x)*S(u;x)}
where S(u;x) = exp{-sum_of_k(sum(hazard_k(u))}
I have searched extensively for an implementation of this in many
packages, but it appears that more complex approaches are more commonly
implemented, such as timereg package.
