Your example is incomplete (what is x?), but axis(1, at=0.5) may be what
you are looking for.

I wanted essentially the same image as plot(stl..) but with individual
control over ylim for each of the 4 plots. In that case, I might make a
local copy of the actual plot function using 'getAnywhere(plot.stl)'
and

You might try posting your problem on the comp.os.linux.networking

If all else fails, you can try using the system method of connecting to

Greetings list,
In my code, I have a few small functions that are called very very
frequently. An example of one such function is the following :
sigmoid-function(x) 1/(1+exp(-x))
Now, is there anyway to make this go faster? For example, in C++ we
could make it inline. Is there a
You ask whether there would be a way to adapt the deriv and
deriv3 functions to deal with formulas that have an indexed term,
effectively allowing differentiation with respect to a vector. As Simon
Blomberg famously said, This is R. There is no if. Only how.(*)
The implementation,
Try a test in which you replace the function calls with inline
code and compare the two speed-wise. You may very well
find that the difference is inconsequential.

Hi Gabor,
Your version works with the small sample matrix but I didn't get it to work
with a larger 675x8 -matrix. I don't know why. I don't know the command

I got this one from Peter Alspach

A slight glitch got-in during the copy and past.
The part below that says,
ms.curv(dd.nls.d4)
Parameter effects: c^theta x sqrt(F) = 0.0123
Intrinsic: c^iota x sqrt(F) = 0.0068
should read,
rms.curv(dd.nls.d4)
Parameter effects: c^theta x sqrt(F) = 0.0123
Intrinsic: c^iota x
Wee-Jin,
The other option that you have is to set up your function as an expression
and then evaluate the expression for each new value of x. This might be
faster in some cases.
sigmoid.fun - function(x) 1/(1+exp(-x))
sigmoid.expr - expression( 1/(1+exp(-x)) )
x - runif(10^6)

Apparently, the link
HowTo - Enable Telnet on Linux
at Ryacas site is misleading, as it suggests
I don't have a UNIX box but my reading of it is that it is
telling one how to enable telnet on the machine -- not
how to install a server -- and that once telnet is enabled
then the Ryacas package can make use of sockets
whereas without that such use of sockets is disabled.
Is that not right?

I had an offline discussion with the Debian user and he indicated that
the yacas invocation string was his problem and not telnet at all so I will
remove that HowTo as it is indeed misleading.

Gabor,
From what I can tell, telnet service is not actually required to run
yacas. This is what confused me for some time and what raised the
spectre of the concerns that had I for yacas to be dependent on telnet,
as opposed to say ssh.
On FC6 (and I suspect many other distros), telnet (plus or
