Dear R users,

I'm using Ecdf (Hmisc library) to plot four cdf in a same graphic. In this
graphic I also plot the 0.99 quantile for these cdf.

How did you do this? Experimenting with the example on hte Ecdf help page it appears that adding lines with abline works fairly well, despite this being a mixture of lattice and base graphics.

I successfully plot
cdfs using different types of line to distinguish them, but I can't
determine the type of lines showing 0.99 quantile.

Is there a way to assign different line types for quantile lines in Ecdf
plot?

What do you mean by "quantile lines"?
