similar to: Need help with xspline error message in R 2.6.1 on Windows XP

Hello, I am having two difficulties with xspline: 1) Passing lty=2 (via ...) appears to have no effect 2) Apparently depending on the current plot axes, I may or may not get the failure: add_point - reached MAXNUMPTS (25200) This happens both on Linux/R 2.8.0 (details below) and Windows Vista/R 2.8.0 patched (2008-10-21 r46766) Simplest case: plot(c(0,1),c(0,1))

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

I have a set of Monte Carlo simulation results for a Quick Response Freight Model that I am currently preparing summary graphs. I want to show three things on the graphs; the model forecast, an approximate exponential best fit line, and a smooth line through mean+sd and mean-sd data points. As you can see I can get the first two, but all I can find when searching the help are references to

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.

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

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.

Dear list, Can someone explain why the childNames below gives character(0) instead of the (canonical) names of the children grobs of the xaxis gTree ?

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. Allan.

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

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'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.

Hello list, When using the grid package in R 1.60 under windows grid.lines and grid.line.to seem not to use the coordinate system as defined by the current viewport whereas grin.points does.

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.

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)

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?

I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis()
