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
