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*
<-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)
*Column 2* is an indicator for censoring "*1*" for left censored
observations and "*0*" for non-censored (fully measured)
observations.
And what, pray tell, do you want the resulting histogram to look like?
See e.g. fortune("mind_read").
cheers,
Rolf Turner
