Need help with xspline error message in R 2.6.1 on Windows XP
I am attempting to generate a series of plots with cubic B-Splines and
the code I am using is generating the following error message that I
have been unable to resolve.
Error in grid.Call.graphics("L_xspline", x$x, x$y, x$shape, x$open,
x$arrow, : add_point - reached MAXNUMPTS (25200)
This is the code that generates this error.

xspline(..., draw=FALSE) fails if there is no open device (PR#10727)
Full_Name: Jari Oksanen
Version: 2.6.2 RC (2008-02-07 r44369)
OS: Linux
Submission from: (NULL) (130.231.102.145)
Even if function xspline() is called with argument draw=FALSE, it requires a
graphics device (that it won't use since it was draw=FALSE). I run into this
because I intended to use xspline within a function (that does not yet draw:
there is plot method for that), and the function

R 2.8.1 is released
I've rolled up R-2.8.1.tar.gz a short while ago.
This is a maintenance release and fixes a number of mostly minor bugs
and platform issues.
See the full list of changes below.
You can get it (in a short while) from
http://cran.r-project.org/src/base/R-2/R-2.8.1.tar.gz
or wait for it to be mirrored at a CRAN site nearer to you. Binaries
for various platforms will appear in due course.

smoothed contour lines
Hi all,
I'm trying to draw a contour plot
with rounded (smoothed) contour lines instead of sharp angles;
when the grid consists of only a few points
in x- and y- axis, the resulting contour
is in facts rather ugly since very sharp angles may appear.
I did not find any way to do it,
by using either "contour" or "contourplot" (from the lattice package),
I wonder if there

Drawing curves
Hi,
Am looking for an R package that will provide the drawing of curves and
arcs of arbitrary shapes to use in illustrations. For example bent lines
and arrows.

Smooth line in graph
Hi,
I?m trying to get smooth curves connecting points in a plot using
"spline" but I don?t get what I whant.
Eg.:
x<-1:5
y <- c(0.31, 0.45, 0.84, 0.43, 0.25)
plot(x,y)
lines(spline(x,y))
Creates a valley between the first and second points, then peaks at 3rd,
and another valley between 4th and 5th. I?m trying to get a consistently
growing curve up to the 3rth point and then a

Is it possible to install (and run) CentOS-3 with
only 160 MB of RAM?? Have I put special params to boot
it??
Thank you very much

hermite and Bezier splines
Does anyone know how to do hermite or
Bezier splines in R? I can find Matlab routines, but really need to
implement them in R. Failing that I'd be interested in other
conformal splines. I need to smooth and interpolate animal tracking data.

smooth scatterplot and geo map
Hello everybody,
I'm trying to understand how to draw a smoothed scatterplot on a geographic
map with R.
Have a dataframe with point locations (long, lat) and was able to simply
plot these points on a shp map by using the maptools package. However,
instead of having simply the raw points on the map, I would like to have a
"smoothed" scatterplot of the same superimposed on the map.

[LLVMdev] LLVM code target dependent generator question

I am new to LLVM and I am not sure whether I am writing to the right distribution list or not. Please let me know if this is not the right distribution list.

- I am having hard time lowering ADD instructions for different purposes. Basically, I want to have different machine instruction for pointer addition vs scalar addition. I am having hard time mapping LLVM add to my machine

how to evaluate a cubic Bezier curve (B-spline?) given the four control points
I'm trying to use R to determine the quality of a cubic Bezier curve
approximation of an elliptical arc. I know the four control points
and I want to compute (x,y) coordinates of many points on the curve.
I can't find anything in either the base distribution or CRAN that
does this; all the spline-related packages seem to be about *fitting*
piecewise Bezier curves to a data set.

Connecting points on a line with arcs/curves
Hello,
I have a spreadsheet of pairs of coordinates and I would like to plot a line
along which curves/arcs connect each pair of coordinates. The aim is to
visualise the pattern of point connections.
Thanks! Ian

order of points in spline
Hello everyone,
I was trying to fit a spline to some points and I was quite surprised to
find out that the function spline does not take into account the order of
the points themselves, but orders them by x.
For instance, I have:
x <- c(262, 275, 264, 250, 247, 242, 238, 233)
y <- c(422, 389, 359, 308, 269, 229, 191, 176)
plot(x, y, xlim=c(0, 500), ylim=c(0,500))
s <- spline(x,y)

Curved arrows
I'm trying to draw an arrow with a curved shaft on the graph as a straight
one looks messy on a detailed graph. I've looked in arrows but it doesn't
seem to give an option. larrows doesn't look much more promising. I had a
look in the archive and couldn't find anything. Any thoughts?
Thanks

pointer arithmetic with address space attribute not working
Hi,
I have a case that for pointer with address space attribute, pointer
arithmetic is not work.
For example,

void __user * test(void __user *arg) {
#ifdef ADD
return arg + 4;
#else
return arg;

}

-bash-4.4$ clang -g -c test.c
