RcmdrPlugin.KMggplot2 depends survfit
function of survival package. Dataset requirements are same
as survfit function, which works with Surv
objects.
Surv objectSurv objects are generated from Surv
function. RcmdrPlugin.KMggplot2 calls as follows:
time
event
type
RcmdrPlugin.KMggplot2 can only handle “right”
censoring.z, s, t
z) and the facet (s,
t) variables (factor variables)..df
RcmdrPlugin.KMggplot2 requires a data frame that at
least includes time and event variables, and
includes z, s, t if you needs
| time | event | trt | sex | marker |
|---|---|---|---|---|
| 17.540935 | 1 | Group-C | M | Low |
| 16.520777 | 1 | Group-A | M | Low |
| 6.530335 | 0 | Group-A | M | High |
| 10.701766 | 0 | Group-B | M | High |
| 4.779544 | 1 | Group-A | M | Low |
| 20.000000 | 0 | Group-C | M | Low |
| 19.527943 | 1 | Group-B | M | Low |
| 13.065791 | 1 | Group-B | M | High |
| 8.710817 | 1 | Group-A | M | High |
| 14.460404 | 1 | Group-B | M | Low |
In this case:
time: “time”event: “event” (0 = alive (censor), 1 = dead
(event))z, s, or t: “trt”, “sex”, or
“marker”
