Zuki,

You did not provide any information on what table$attrib is.  Using a log 
scale for the y-axis doesn't make much sense to me, since the y-axis is 
the cumulative proportion of observations, from 0 to 1.  Perhaps you are 
interested in the log scale for the x-axis, instead?  In any case, log is 
not an argument to the plot.ecdf function.  You could take the log of the 
values then plot the ecdf, like this:

plot.ecdf(log(1:100), axes=F)
axis(1, at=log(tix), labels=tix)
axis(2)
box()
