Hello,
I now receive an error message when obtaining a survival plot, which
was not previously received with the same code. I recently updated
all my packages. It does not seem to be a peculiarity of my data as I
receive the error using data available in R. A plot is produced but I
am uncertain regarding the error message.
> library(surv2sample)
> data(gastric)
> fit <- survfit(Surv(time, event) ~ treatment, data = gastric)
Error in get(x, envir = ns, inherits = FALSE) :
variable "survfit.km" was not found
> #Default plot:
> plot(fit)
regards
Bob Green
