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.

Error in get(x, envir = ns, inherits = FALSE) :
variable "survfit.km" was not found
