Number of observations contributing to a fitted flexible survival model
# S3 method for flexsurvreg
nobs(object, cens = TRUE, ...)This returns the mod$N component of the fitted
model object mod. See flexsurvreg,
flexsurvspline for full documentation of all components.
Output from flexsurvreg or
flexsurvspline, representing a fitted survival model object.
Include censored observations in the number. TRUE by default.
If FALSE then the number of observed events is returned. See
BIC.flexsurvreg for a discussion of the issues
with defining the sample size for censored data.
Further arguments passed to or from other methods. Currently unused.

By default, this matches the behaviour of the nobs method for survreg objects, including both censored and uncensored observations.
If a weighted flexsurvreg analysis was done, then this function returns the sum of the weights.
