I only see an "lm" method for simulate, so I think you are getting that by

As ?simulate says fairly clearly that there is only an "lm" method in base

You are *copying* the plot, and that means copying the background too (it
*is* part of the plot). Almost certainly the plot you are copying had a
transparent background: that is the default for X11.

You are using fitted() implicitly here, so you are not plotting a smooth
curve but a set of fitted values.
You need to really predict at a suitable range of data points, e.g.
xx <- seq(1, 10, len=500)
plot(xx, predict(w, list(x=xx)), type="l")
BTW, why are you not using poly()?

It is baffling,
What value should your formula give when x is a multiple of 2*pi?
You seem to believe 9 is correct but in fact NaN is.
Element 701 of x is approximately but not exactly 2*pi: on my system
it is about 7*.Machine$double.eps different. You cannot expect sin(N*pi)
to be exactly zero for N != 0.

It certainly does! Try col="transparent" (and perhaps consult your

Note that the use of read.table() does make a difference. If you did
x <- scan(gzfile("xxx.gz"), list("","",""))
you would leave an unused connection, and showConnections(all=TRUE) would
show this. There is a finite pool of connections, and in general the
correct way to use them is

1) You are not supposed to have R_HOME set in your environment: that is
the job of the R front-end script.
2) R 2.4.1 is obsolete, but I believe the relevant line is
. "${R_SHARE_DIR}/sh/dcf.sh"# get_dcf_field()
R_SHARE_DIR is set in the R front-end script, so that's where to
investigate.
ease see the help page of the devices you recommended, which did warn
about this.

You need to forward the X11 window to your local machine, which would need
to be running an X server. We do this using Exceed and PUTTY settings,
but your sysadmins will be able to help you: it is not a question about R
per se.

As embedFonts creates a new file, the bounding box of the original one is
not relevant. (Yes, outfile = file by default, but it is still a new
file.)
I guess the switches
-dDEVICEWIDTHPOINTS=w -dDEVICEHEIGHTPOINTS=h
might help to create the new file with the bounding box you want.

One of your home directories on Windows is %HOMEDRIVE%%HOMEPATH% (you do
need to give the drive), but only one: see the rw-FAQ.
Reading ?file.path will help you not reinvent the wheel.
So I think attach(path.expand("~/MMmisc.rda") is far more portable (as
well as much more readable).
