R help - Dec 2002 - log axis error

Hi,
When trying to benerate a barplot with a log y axis from a data matrix I get an
error which I just cant figure out:
> barplot(col.groups,beside=T,log="y")
Error in plot.window(xlim, ylim, log = "", ...) :
        formal argument "log" matched by multiple actual arguments

Can anyone tell me what this error means and possible solutions
Cheers, Jeremy

Jeremy,

Log scale axes are not presently supported in barplot().

Look for the barplot2() function in the gregmisc package on CRAN.
That supports log scale axes and other features.

If you have any questions on its use, let me know.

Best regards,
