Dear All:
*P.S.* I submitted this request to r-h...@r-project.org , but did not get any response. I am not sure, what is wrong. I already subscribe to this list too. 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. with many thanks steve -- Steven M.
