R help - May 2013 - ecdf --- title suggestion and question

dear R-experts---first, a suggestion to martin: the ecdf() function
could have an optional parameter to set the title.  by looking at
str(), I see the plot title is set in an attr named "call".  i.e., I
can reset it as

ee <- ecdf( rnorm(25 ) )
attr(ee,"call") <- "my own title"
plot(ee)

alas, I cannot figure out how to get rid of the title altogether.
attr(ee,"call") <- NULL gives me two quotation marks ("")
.  is it
possible to remove the title altogether?

regards,

/iaw

Why not just:

R> plot(ee, main="my own title")
> alas, I cannot figure out how to get rid of the title altogether.

R> plot(ee, main="")
R> plot(ee, main=NULL)
