[R] plot() error-msg: "need finite xlim values"

[Christoph Lehmann]

Hi
I try to plot a ROC curve, using the ROC library from bioonductor (using
the example in the help). Everything runs nicely except, that finally I
get the error: "Error in plot.window(xlim, ylim, log, asp, ...) :
        need finite xlim values"

Error in plot.window(xlim, ylim, log, asp, ...) :
        need finite xlim values
In addition: Warning messages:
1: no finite arguments to min; returning Inf
2: no finite arguments to max; returning -Inf
3: no finite arguments to min; returning Inf
4: no finite arguments to max; returning -Inf
