plotting pie chart in R with zero value of one of the divisions

Question

I am trying to plot a piechart in R using data present in a data-frame.It is possible that the values can be zero at times.In this situation ,R is throwing an error How to overcome this issue?

slices<-c(pu1_500,pu501_1000,pu1001_2000)
     cols <- c("red","blue","green")
     percentlabels<- round(100*slices/sum(slices), 1)
     pie3D(slices,main="piechart",col=cols,labels=percentlabels,explode=0.1)
     legend("topright", c("1-500","501-1000","1001-2000"), cex=0.8,fill=cols)

here let us suppose that ' pu501_1000 ' has value 0,then i get the following error:

Error in if (length(by) && by == 0 && length(del) && del == 0) return(from) : missing value where TRUE/FALSE needed

Please provide a reproducible example (http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example). We don't know how `pu1_500, pu501_1000, pu1001_2000` look like. — Qaswed, Jun 21 '16 at 10:07
I can't reproduce the error. If I take your code and set `slices<-c(0, 5, 7)` then I get a nice pie chart. — Martin Schmelzer, Jun 21 '16 at 10:08
@MartinDabbelJuSmelter i am able to produce a normal pie chart . But if i try to use pie3D instead of pie ,then i am getting that error. I have included the necessary libraries. — pixey, Jun 21 '16 at 10:41
@pixey as i said i only modified `slices` and it works for me with pie3D. — Martin Schmelzer, Jun 21 '16 at 10:44
@pixey the only thing I could think of are outdated package versions... — Martin Schmelzer, Jun 21 '16 at 11:03

A bit outdated but I also run into the same error when plotting 3D pies when one of the elements had 0 value. In my case, it helped to just subset my "slices" excluding the element that had 0 value. I guess in the case above it would work like this:

pie3D(slices[c(1,3)], main= "piechart", col=cols, labels=percentlabels, explode=0.1)

Note: 1 & 3 are the positions of the non-zero elements in the "slices" vector.
