Convert time-to-event data (typically created with the Surv
function) to factor or integer.
dichotomize(x, time, to_factor)Surv vector.
Time point to dichotomize at.
Depending on the type of x the return value may be
integer or factor. Set this argument to explicitly state the return type.
Integer vector or factor.
If no time point is given the observation times will be stripped, leaving
only the event types. If a time point is given
observations with events occurring before time will be labelled by
their event type,
observations with events occurring after time will be labelled as
“no event”, and
observations censored before time will be considered as missing
information.
