[R] errbar won't provide log axes

[Kenneth Benoit]

Dear R users,

I am constructing a horizontal error bar plot with Hmisc's errbar() 
command and I cannot get it to keep the par(ylog=TRUE) setting, nor to 
pass the argument as the documentation supposedly says should work.

In other words

errbar(df$x,df$y, df$yminus, df$yplus, log="y")
or
errbar(df$x,df$y, df$yminus, df$yplus, ylog=TRUE)

yields the same unlogged axis as
errbar(df$x,df$y, df$yminus, df$yplus)

and if I set par(ylog=TRUE)
then it resets to FALSE following the errbar() call.

Please note that I searched everywhere through the R-help archives and 
on the Internet generally and have not found any mention of this 
problem.  Many thanks for any help.

Ken
