Hi,
I am having trouble with an error I keep getting. I am just trying to create
a simple pic chart from a small table. Hope someone can help. I am new to R.
Table:
Name Votes
John 300
Sean 222
Andy 467
Sinead 740
David 124
James 641
William 380
Commands:
d <- read.table("C:\\rep.csv", head=TRUE,
sep=",")> pie(d$Votes,
+ labels=d$Name,
+ main="Class Rep Results\n(Final Results)")
Error:
Error in pie(d$votes, labels = d$name, main = "Class Rep Results\n(Final
Results)") :
'x' values must be positive.
Hope to hear from someone soon....
Best Regards,
John.

Take a look at what you have stored in the data frame d; it is possible that the data has been read into R incorrectly. Type d and str(d) at the command line to see this. Also, you might want to use read.csv to read in your data if it is comma separated value format. Regards, Richie.

It looks fine to me. Try str(d) and check to be sure
that Votes is a numeric value or integer value.
I ran this code with no problem.
x <- "Name Votes
John 300
Sean 222
Andy 467
Sinead 740
David 124
James 641
William 380 "
d <- read.table(textConnection(x), header=TRUE,
as.is=TRUE); d
pie(d$Votes, labels=d$Name, main="Class Rep
Results\n(Final Results)")
