[amelia] Log-log plots from overimpute

I would like to produce log-log plots from overimpute. If I try adding a graphical parameter, log='y' I get an error Error in plot.window(...) : Logarithmic axis must have positive limits My data are all positive. Looking at the code for overimpute, there is a variable addedroom <- (max(uppers) - min(lowers)) * 0.1 which is then used as part of the ylim argument for the plot ylim = range(c(lowers - addedroom, uppers)) I think this is making the y-axis go slightly into negative territory so the log doesn't work. Can anyone suggest a work around? -- E: tony.ladson(a)moroka.com.au M: 0408 440 028 A: P.O. Box 1245, Fitzroy North, Vic 3068 B: http://tonyladson.wordpress.com/
