similar to: [PATCH]Make wobbly's bezier patch to work with grids that aren't 4x4.

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.

Hi dear all, I am wondering if there is a function existing in R that did the quadratic bezier curve interpolation? I hope to generate a bezier curve based on three sets of points: two end of the line and a control point. Thanks in advance.

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.

Hello, I'm a grad. student in statistics and am looking for some information on how R draws its contours. I suspect you are using a Bezier spline. I have the C code but am curious about how it works.

Hi all, I am trying to compile Rgraphiz on Windows 7 64bit with R-2.13.0. I have installed Rtools213.exe from [1]. The 64bit packages in [2] provided me with the 64 bit version of graphviz. After intalling the binary version Rgraphviz 1.30 (in 32bit) it complains (as expected) that: > library(Rgraphviz) Error: package 'Rgraphviz' is not installed for 'arch=x64' I

I have the following data table: [,1] [,2] [,3] [,4] [,5] [1,] 2575 1927 1754 581 354 [2,] 1156 810 730 541 237 [3,] 417 297 199 125 110 [4,] 281 132 132 47 58 [5,] 152 84 87 54 19 Each column represents a time interval expressed in nano-seconds Each row represents an energy interval expressed m=n MeV Each table value represents the average gamma rays intensity

I am having a problem using two DLLs with the same name, but obviously located in different directories, in an R session. The troublesome package is the (Bioconductor) Rgraphviz package. It relies on (3rd party software) graphviz and imports functions from (Bioconductor) package graph. Unfortunately, the current stable release of graphviz for Windows

The Wine development release 2.15 is now available. What's new in this release (see below for details): - Support for AES encryption. - Improved Bezier support in Direct2D. - Chunked transfer improvements in WinInet. - Various bug fixes. The source is available from the following locations: http://dl.winehq.org/wine/source/2.x/wine-2.15.tar.xz

The Wine development release 2.0-rc1 is now available. This is the first release candidate for the upcoming Wine 2.0. It marks the beginning of the code freeze period. Please give this release a good testing to help us make 2.0 as good as possible. What's new in this release (see below for details): - Bug fix update of the Mono engine. - Support for IDN name resolution. - Many more

xf86-input-libinput 0.24.0 is now available. A couple of new features were added this cycle: * tablets now support a configurable pressure curve * tablets now have a 'area ratio' setting to be able to match the tablet aspect ratio with that of the screen * the mouse wheel's click angle now (correctly) affects how fast the scroll wheel triggers. In particular, if you have a wheel

I think I have a spline problem, and I would like to implement the solution in S. There are a lot of spline algorithms and I am looking for some direction on what is most appropriate. I need a spline that can be made to extrapolate certain data points as described below. Of course it needs to happen algorithmically as I have lots of this data. Can a Bezier be fit to data? Consider a material

Hello All, I am in need of sample code to create gnuplot's sbezier output in numerical form. Below are some details of what I have done. I just fed 2000 lines of data to the above gplot script and it seg faulted, when I cut the data down it down it worked fine. The results are very good for the purpose, which is to give a guestimation as to what fills the spaces between the exceptions.

November 21, 2005 — The Inkscape community today releases Inkscape 0.43, an Open Source Scalable Vector Graphics (SVG) drawing tool available for Unix/Linux variants, Mac OS X, and Windows. The focus of this release is on the exciting new features sponsored by Google through their Summer of Code (SoC) program which provided funding for four individuals to contribute to Inkscape. The

Hello, I am author of a Morse code training software written in Perl at http://starling.ws/morse Currently I output to *.wav and, if on Unix, convert to *.ogg. And that's okay for a trainer. But I have desire to upgrade the project to a real-time communication tool...or at least a Morse code audio mail routine. And I should like to avoid *.wav. I'd like some means of writing a pure

Hello all, I discovered that the pdf device uses fonts to represent "points" symbols (as in plot(...,type="p",...) ). Namely it uses ZapfDingbats with symbol U+25cf. This can lead to problems when the font is not available, or available in another version (such as points being replaced by other symbols, or worst: slightly displaced). Furthermore, it also causes

Hi, This is a bug of sorts, relatively minor. When clicking on the title bar of a window and moving the mouse slightly, there will be a wobble that seems to propagate in coordination with window snapping which results in a feedback cycle. I'm sure other people have experienced this. 3 others in the Ubuntu channel last night knew what I was talking about. Is there any way to resolve this? A

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've made these patches that basically, make the java apps and firefox items well being recognized by some compiz plugins (scale, switcher and wobbly), I don't know if those can be considered workaround, but this helps in using your desktop tools. Basically java apps are seen as: * name=sun-awt-X11-XFramePeer (default windows = Normal) *

Hi, I notice a bug if I start wobbling unminized window before the minimizing effect is finished. Here's the video (flash): http://www.youtube.com/watch?v=DttpjXFqbis Does anybody else notice this? Stjepan
