[R] Histogram for grouped data in R

[Mendiburu, Felipe (CIP)]

Ok,
use library agricolae, graph.freq() is similar hist(), aditional parameters
 
size<- c(0,10,20,50,100)
f<-c(15,25,10,5)
library(agricolae)
h<-graph.freq(size,counts=f,axes=F)
axis(1,x)
axis(2,seq(0,30,5))

Other function:
# is necesary histogram h with hist() or graph.freq()
h<-graph.freq(x,counts=f,axes=F)
axis(1,x)
normal.freq(h,col="red")
table.freq(h)
ojiva.freq(h,type="b",col="blue")

Subject: [R] Histogram for grouped data in R




I have grouped data in this format

Size  -- Count
0-10 --  15
10-20 -- 25
20-50 -- 10
50-100 -- 5

I've been trying to find a way to set this up with the proper histogram
heights, but can't seem to figure it out. So any help would be much
appreciated!
