R - Pie, X values must be positive

Question

I am new to R and drew some testdata about countries in a csv from the web. I am currenty fooling arround with plotting and encountered said error while creating a pie chart of the worlds unemployment.

i issued the following:

>values <- read.csv("D:\\test\\countrydata.csv")
>names(values)
 [1] "name"    "size"    "pop"    "unemployed" ...
>typeof(values$unemployed)
"integer"
>pie(values$pop)
Error in pie(values$unemployed) :
    'x' values must be positive
>pie(values$pop, na.rm=TRUE)
Error in pie(values$unemployed, na.rm=TRUE) :
    'x' values must be positive

The dataset i want to plot is a set of integers, all of them are positive, 0 (thanks kim) or NA.

0 are not a problem when plotting integers, i tried

>pie(as.integer(c(0,1,2,3))

and it worked fine.

What am i missing here?

Thanks and Regards,

I don't have access to your data but in my experience the following might help and is definitely worth a try:

pie(table(values$unemployed))

Would love to learn whether this solved your problem!
