R help - Oct 2009 - roc plot with zero length labels error

I am trying to create the roc plot bootstrap method from library(verification),
and when I set the plot =both or emp then I get the following error. The
roc.plot works fine when the plot is set to binorm. This is my first time using
this function in R and am not sure what this error means or how to resolve the
issue. It seems to work ok with the example dataset. Is there an option or data
formatting I need to due to resolve this error?
 
roc.plot((scicomp5.model1[164]=="High Price"), pred, CI = T, n.boot =
100, plot = 'both',binormal = TRUE,
+          main = paste('AREA UNDER CURVE (AUC) =', round(auc$A, 2)))
Error in text.default(DAT[id, 3, i], DAT[id, 2, i], plot.thres[id2], pos = 4,  :
  zero length 'labels'

[Going through some old and from what I see unanswered messages

Hard to tell what is going on without telling us the data. Works with 
the examples, so may be related to one of the objects scicomp5.model1, 
pred, T, or auc.
