having been bitten by this behavior many times, could I register a
plea for
allowing a col argument to plot.stepfun that would deal with both the
horizontal
and vertical segments -- I rather doubt that it is often desirable to
have different
colors for these. Note that verticals = TRUE is the default here so
not strictly
necessary in the example below.

Does not work for me with rnorm(20) as an argument. (And supplying a
dummy value for DIM.) The error after fixing the missing DIM issue
was:
Error in plot.stepfun(x, ..., ylab = ylab, verticals = verticals,
pch = pch) :
argument 4 matches multiple formal arguments
The help page for plot.ecdf refers me to plot.stepfun (and the error
message did too) which does not have a col= argument but rather
col.hor= and col.vert= . Using those arguments instead of col="red",
it now "works".
plot(
ecdf(rnorm(20)),
do.points=FALSE,
verticals=TRUE,
main=paste("Ecdf of distances "),
col.hor="red", col.vert="red"
)

Hi.
I have the following two ecdf plots in one graph:
plot(
ecdf(....),
do.points=FALSE,
verticals=TRUE,
main=paste("Ecdf of distances ",DIM,sep=""),
col="red"
);
lines(
ecdf(....),
do.points=FALSE,
verticals=TRUE
);
How do I change the color of the resulting graph? Adding col="red"
to either plot or lines results in an error ...
... but works for me.
Hence please specify your version of R, OS, exactly reproducible
code (above the argument to ecdf are missing, obviously).
