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
a[1,]<-c(145,60,147,62,140,57)
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?
As always, Thank You. ~Erithid

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 Uwe Ligges wrote:> BJ wrote: > >> I am trying to construct a graph of 6 box plots of blood pressures.

Your code for creating "a" # is not replicable. For those lacking clinical insight, explaining # your acronyms would also be helpful... :-) SBP <- matrix(c(145, 160, 140, 147, 160, 140, 140, 160, 142), ncol = 3) DBP <- matrix(c(60, 75, 55, 62, 74, 65, 57, 70, 55), ncol = 3) colnames(SBP) <- colnames(DBP) <- c("sit","lie","stand") # The key here is to only plot three at a time, lest boxplot() # default to a 'xlim' of 0.5 to 6.5 (1:# of groups +/- 0.5) # Then use 'add = TRUE' to plot the second group of 3 # Note also that I set the 'ylim' to the range of the combined # values in the first plot. boxplot(data.frame(SBP), main = "Blood Pressures", ylim = range(c(SBP, DBP)), whisklty = 0, staplelty = 0) boxplot(data.frame(DBP), add = TRUE, whisklty = 0, staplelty = 0) Note the final two arguments, which result in the whiskers being drawn with an "invisible" line. See ?boxplot and ?bxp for more information. HTH, Marc Schwartz
BJ- For the record as well I could not make heads or tails of your question. The dedicated folks who day in, day out field poorly specified questions have no obligation to do so, and have every right to get frustrated when it seems that their time is being taken advantage of.
