anyone encountered the same message while using kmTCGA?

Scale for 'colour' is already present. Adding another scale for 'colour', which will replace the existing scale.
Scale for 'fill' is already present. Adding another scale for 'fill', which will replace the existing scale.
Warning message:
In .get_data(fit, data = data) :
  The `data` argument is not provided. Data will be extracted from model fit.
 

Many thanks! By the way, Is there play to update the RTCGA package to the latest TCGA data?

Thanks

Hello,

I am using ggsurvplot (package survminer) and I had the same problem:

Warning message:
In .get_data(fit, data = data) :
  The `data` argument is not provided. Data will be extracted from model fit.

kmTCGA uses ggsurvplot to plot the nice Kaplan Meier. Probably the issue lies there.

 

  Dataset$TimeToEvent <- with(Dataset, Surv(Time_to_event, Event == 1))
  fit <- survfit(TimeToEvent ~ 1, data=Dataset, conf.type = "log")  
  ggsurvplot(
   fit,    # survfit object with calculated statistics.
   data=Dataset,            # dataset
   risk.table = TRUE,       # show risk table.
   ncensor.plot=TRUE,
   risk.table.y.text=FALSE,
   legend.title = "",
   conf.int = TRUE       # show confidence intervals for 
                            # point estimaes of survival curves.
    )

 

If you don't specify the data=Dataset you will get the message.
