You might want to have a look at the qcc package. See http://www.stat.unipg.it/~luca/Rnews_2004-1-pag11-17.pdf for some information Following is the approach > I took. > > My data looks like this > df2_9 > Reaason.for.failure Frequency > > 1 Phy Conn 1 > > 2 Power failure 3 > > 3 Server software 29 > > 4 Server hardware 2 > > 5 Server out of mem 32 > > 6 Inadequate bandwidth 1 > > > I modified the data using: > > df <- > df2_9[order(df2_9$Frequency,decreasing=TRUE),] > > x$Percent <- 100*(x$Frequency)/(sum(x$Frequency)) > > ReasonCode Frequency ROF Percent > > 5 OOM 32 Out of Momeory 47.058824 > > 3 SS 29 Server Software 42.647059 > > 2 PF 3 Power failure 4.411765 > > 4 SH 2 Server h/w 2.941176 > > 1 PC 1 Physical Conn 1.470588 > > 6 IB 1 Insuff b/w 1.470588 > > > > barplot(x$Percent, space=0, names.arg=x$ReasonCode, > main="Pareto", legend.text=x$ReasonCode, ylab="% > error") > > > > Here are my questions: > > 1.

Given the lenght of the names you may have a problem. ?mtext is the obvious way but the names are too long. Have a look at http://finzi.psych.upenn.edu/R/Rhelp02a/archive/80007.html for rotating the labels or use the staxlab function in plotrix (see below) > 2. Can I color code each bar differently > > 3.
