R help - Sep 2009 - (no subject)

Hi r-users,
 
I would like to know how to put all the data that is greater than certain value
in certain cell for my histogram.  For example, since maximum value of p1 is 588
it doesn't fit in the breaks that we specified.  Can we write breaks
>300?
 
max(p1[,2])
pre.hist <- hist(p1[,2],breaks = c(0,50,100,150,200,250,300),right=FALSE)
 
> max(p1)
[1] 587.2761
> pre.hist <- hist(p1[,2],breaks =
c(0,50,100,150,200,250,300),right=FALSE)
Error in hist.default(p1[, 2], breaks = c(0, 50, 100, 150, 200, 250, 300),  : 
  some 'x' not counted; maybe 'breaks' do not span range of
'x'
> max(p1[,2])
[1] 587.2761

Thank you.

Hi Roslina,

x<-runif(1000,min=0, max=600)
hist(x)

x2<-ifelse(x<=300,x,300)
summary(x2)
hist(x2, ,breaks = c(0,50,100,150,200,250,300))
 good luck
