在R包中包含“生存”功能

Question

I would like to include in my R package a new function, which requires the Surv function from the survival package. I did include import(survival) in the NAMESPACE and I have survival installed; however, when I run R CMD check, I still get this error message:

Error in Surv(time, status) : could not find function "Surv"

I do have dependencies from other packages and I never faced such an issue. I already tried with no success to implement the solutions recommended here:

Any suggestions on what might be the problem?

Answer 1

You have to do the following

1. install.packages("survival")
2. library("survival")

and then the surv() function will work
