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.
