Hi Tom,
Thank you for the friendly and informative answer. It does explain a lot of
things, actually. As with any good answer, it inevitably leads to other
questions. In the first place, I need the arithmetic mean. It's what we

Hi Michael,
Looking at the help for beanplot(), note that the 'log' option defaults to
'auto' which means the function will automatically log-transform data like

Hi there,
I have a set of data that looks like this:
As1988-c(1254.0, 22.0, 4.2, 1081.0, 35.0, 6.0, 1772.0, 192.0, 7.6)
The mean of this (as calculated by R) is: 485.9778
The median of this (as calculated by R) is: 35
If I then make a beanplot(As1988), I find that the beanline (average)
Hi,
The log of the mean is not the same as the mean of the logs, that's a
no-brainer. Guess you use the beanplot from the package with the same
name.
beanplot(As1988,log=)
gives the correct plot.
Next time, could you provide a minimal code example we can run
ourselves? If we don't know what
Hi Michael,
Looking at the help for beanplot(), note that the 'log' option defaults to
'auto' which means the function will automatically log-transform data like
yours. This also implies that the mean it shows is the geometric mean, not the
arithmetic mean. As you note, the transformation
