Feature request: Function to add confidence bands

[tobiasmuetze]

The function add_confidence_interval() add pointwise confidence intervals to the Kaplan-Meier curve. In same settings confidence bands (and not pointwise confidence intervals) are of interest.

It would be great to add a function add_confidence_bands() to the package. To the best of my knowledge, confidence bands are not calculated by the survival package. However, the R package km.ci provides confidence bands.

Can you please provide more details about the CI methods you're interested in?
