R help - Sep 2011 - pie chart

Hi All,

I have txt file like :

$ cat data.txt
US	10
UK	12
Ind	4
Germany	14
France	8
> rawdata <- read.table(file='data.txt',sep='\t' ,
header=FALSE)
> rawdata
       V1 V2
1      US 10
2      UK 12
3     Ind  4
4 Germany 14
5  France  8

I want to draw pie chart for the above data.

How to  split rawdata into :
con <-
c("US","UK","Ind","Germany","France");
total <- (10,12,4,14,8)


Any help will be appreciate.

Thanks & Rg
Mohan L

You could do this:
        con <- rawdata$V1
        total <- rawdata$V2

Or you could add in a col.names= argument to the read.table() function,

rawdata <- read.table(file='data.txt', sep='\t',
header=FALSE,
col.names=c("con", "total")) 
then refer to each vector in the data.frame as

rawdata$con

and 

rawdata$total

Hi Mohan,
Anything wrong with:

pie(rawdata$V2,labels=rawdata$V1)
