Dear all:
    The problem occurred while I use the "plot" function of the "dnacopy" package, at first while I typing :

               plot(segment.smoothed.CNA.object, plot.type = "c",pt.cex=1,lwd=2)

every goes well ,
 but when I want add a option to "indicate that the X axis is the maploc position rather than the index", I input the command:

            plot(segment.smoothed.CNA.object, plot.type = "s",pt.cex=1,lwd=2,xmaploc=TRUE)
Error in if (max(maploc0[chrom0 == uchrom[1]]) > min(maploc0[chrom0 ==  : 
        missing value where TRUE/FALSE needed

I get error,can anyone give some guide about how to solve it?
