boxplot with frequencies(counts)

Dear All,

I have a table as following
position type count
1           2     100
1           3      51
1           5      64
1           8      81
1           6      32
2           2      41
2           3      85
and so on


Normally if  would have a vector of 2,3,4,5... by position position and
plot them by position.
But now i have counts of these types.
Is there a way to compute boxplot of such kind of data ?

Hi KM,
We must assume that the "type" variable is to be used as a value, 
otherwise you would want something like a frequency plot by two factors 
of position and type. (If this is the case, I would suggest a nested bar 
plot). Here is a fairly awful kludge that will get you a boxplot (tdf is 
your "table"):

reprow<-function(x) return(matrix(rep(x[1:2],x[3]),ncol=2,byrow=TRUE))
replist<-apply(as.matrix(tdf),1,reprow)
repmat<-replist[[1]]
for(rep in 1:length(replist)) repmat<-rbind(repmat,replist[[rep]])
boxplot(repmat[,2],repmat[,1])

With apologies
Jim
