Hi, I have been trying draw tickmark labels along the y - axis perpendicular to the y axis while labels along the x - axis parallel to x axis while making box plot. Here is my test dataset. TData ID Ratio 1 0 7.075 2 0 7.414 3 0 7.403 4 0 7.168 5 0 6.820 6 0 7.294 7 0 7.238 8 0 7.938 9 1 7.708 10 1 8.691 11 1 8.714 12 1 8.066 13 1 8.949 14 1 8.590 15 1 8.714 16 1 8.601 boxplot(Ratio ~ ID, data=TData) makes box plot with tickmark labels parallel to the y - axis. So I try boxplot(Ratio ~ ID, data=TData, axes=FALSE) par(las=0) axis(1) and I get x - axis ranging from 0.5 to 2.5 (why?) and boxes at 1 and 2. par(las=2) axis(2) box() So, if I set tickmark labels parallel to y - axis somehow the x - axis range is not what I expect even if I use xlim = c(0.0, 3.0) in boxplot(Ratio ~ Id, data=TData, axes=FALSE, xlim=c(0.0, 3.0)) par(las=0) axis(1) Plots are in the attachments in pdf format. I appreciate any tips. I am using R 2.2.0 (2005-10-06) on FC4. Michal -------------- next part -------------- A non-text attachment was scrubbed...

Orientation of tickmarks labels in boxplot/plot

Michal:
and I get x - axis ranging from 0.5 to 2.5 (why?) and boxes at 1 and 2.
See the "at" argument of ?bxp and note what it says there regarding the default. Read the docs more carefully -- ?boxplot has the link to bxp(). Bert Gunter Genentech

I suspect that you want this: boxplot(Ratio ~ ID, data=TData, las = 1) so that the x and y axis labels are horizontal. See ?par and review the options for 'las'. '1' is for axis tick mark labels to be horizontal. The x axis (horizontal axis if the boxes are vertical, the vertical axis if the boxes are horizontal) is set by default to the number of boxes (groups) +/- 0.5. 'xlim' is ignored in both cases. The boxes themselves are placed at integer values from 1:N, where N is the number of groups. There is the 'at' argument and there is an example of its use in ?boxplot. You can also search the archives for posts where variations on the use of 'at' have been posted (recently, in fact...) The actual plotting of the boxplots is done by bxp(), so review the help for that function as well. HTH, Marc Schwartz
