Does it matter what they are? they are just names. The six box plots are from the array I created with columns. I forgot to add teh dim statement, my mistake. But I thought it was obvious that i was using a matrix from the data frame call and the assignments I provided. My question was simply about setting the x axis so that it stopped after x=3, even though I had 6 plots. For teh record, before I get jumped on for the statistics, I am just using a 3 x 6 matrix to test the code before applying it to actual data. Also, I was not being scarcastic. I have recieved a lot of help from this mailing list. The R documentation is hard to hunt down and not complete. Without the help of actual people I would be dead in the water. I am sorry for any hostility that I have incurred. ~Erithid

I am trying to construct a graph of 6 box plots of blood pressures. I want them to be on a single set of axis and I want the SBP to be ontop of the DBP. I have an array bp with the data in it and I tried



Folks, please invest 1 minute of time to rethink whether other people will understand your question!

What is "SBP", "DBP", and where are the "6" boxplots from?

a[1,]<-c(145,60,147,62,140,57)


"a" must already be defined here, or we cannot replace a column!

a[2,]<-c(160,75,160,74,160,70)
a[3,]<-c(140,55,140,65,142,55)
boxplot(data.frame(a), main = "Blood Pressures", at=c(1,1,2,2,3,3), names=c("sit","","lie","","stand",""))

which is close to what I want, but it gives me a bunch of empty space at the end. is there a better way to do this to avoid this?


Well, the first point is that you should write questions that you would understand yourself. In a next step you might find someone who is able to answer it ....

As always, Thank You. ~Erithid


"As always"? Does not sound very enthusiastic ...
