[Rd] plot with Julian date (PR#9145)

[ripley at stats.ox.ac.uk]

You are using the plot method for class "date" from contributed package 
'survival', so it was incorrect to post this as a bug report on R itself.
See

> args(survival:::plot.date)
function (x, y, ..., axes, xaxt, xlab, ylab, log = NULL, xlim = range(x, 
    na.rm = TRUE), ylim = range(y, na.rm = TRUE)) 
NULL

which defaults 'log' to the invalid value of NULL.

Similarly, the warning comes from passing the non-graphics-parameter 
'type' to axis() inside that function.

Please take this up with the package maintainer (as the posting guide and 
FAQ ask).

[You did not get a reply on R-help, at least from me, because you ignored 
the advice to contact the package maintainer.]
