Error in apply(sapply(perfs, c), 1, quantile, probs = c(0 + (1 - conf.level)/2, : dim(X) must have a positive length

[xrobin]

For some reason on this specific dataset the CI of precision with a threshold of 1 is NA.

When calculating the ci.coords with several thresholds, the following error occurs:

> load("roc_error.RData")
> ci.coords(pROC_obj_with_ci, x=c(.5, 1), ret="precision", transpose=TRUE)
  |======================================================================| 100%
Error in apply(sapply(perfs, c), 1, quantile, probs = c(0 + (1 - conf.level)/2,  : 
  dim(X) must have a positive length
In addition: Warning message:

  NA value(s) produced during bootstrap were ignored.
