Dear All:
This is what I was able to come-up with. It looks work good. But not
sure
NH3Nconcentrations.hist<-c(0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,0.009,
0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.02,0.02,0.02,0.02,0.0
Dear David:
Could you please check what I did to create a histogram for this data set.
Actually, I used barplot for myhist$counts. But I have two problems:
*1-* when I rebuild the x-axis, only the label of the first bar appear, but
not for the others.
*2-* I tried to add frequencies at top of ba

How about this?
Sconc<-matrix(c(1450,1800,1840,1820,1860,1780,1760,1800,1900,
1770,1790,1780,1850,1760,1450,1710,1575,1475,1780,1790,
1780,1450,1790,1800,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,1,0,0),
24,2)
Sconc.tab<-table(cut(Sconc[,1],breaks=seq(1450,1900,by=50),
include.lowest=TRUE))

Dear Rolf:
The histogram should contain a bar(s) for the censored data values replaced
by their detection limit(s) with different color than other bars for the
noncensored values . In this example there are only 3 censored values with
only one detection limit of DL = 1450.
with many thanks

Dear All:
I need helps with creating histograms for data that include left
censored observations.
Here is an example of left censored data
*Sulfate.Concentration*
