Please, is there an R function /package that allows for 3D stairway plots like the attached one ? In addition, how can I overlay a parametric grid plot??

Hi, str() on raster objects fails for certain dimensions. For example: > str(as.raster(0, nrow=1, ncol=100)) 'raster' chr [1, 1:100] "#000000" "#000000" "#000000" "#000000" ... > str(as.raster(0, nrow=1, ncol=101)) Error in `[.raster`(object, seq_len(max.len)) : subscript out of bounds This seems to do with how str() and

Ok, now we have the mapping of color names to color codes (see below) and conversion to rgb (something like Ben Bolker's function), but how to convert rgb to hsv? Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker Details below Regards Jens etc/colors.big maps 455 names to rgb in S syntax etc/rgb.txt maps 657 names to rgb in C syntax, but unlike colors() it has mixed upper and

Greetings Friends, is any one knows why i see squirrelmail login interface like below Live Example Can Be Seen Here: https://mail.digital-infotech.com/webmail i have tried to install configure from source as well rather than RPM but all the same.security permissions have been verified also. and i have no clue any more. help would be greatly appreciated Thanks / Regards <> <

Dear Friends Greetings, i am CentOS User for some years now, have installed and configured squirrelmail number of times without issues. but this time it is on CentOS 6.2 x64 - i see very ugly login interface. of squirrelmail, i wish to mention that the package was installed from epelrepo becuse it is not available on centos or rpmforge repo either. i can login also, after login this is how i

Dear All Do you know some functions that can perform the PRINCIPAL SURFACE estimation? Please give me a hint. Thanks for your help in advance. Fred [[alternative HTML version deleted]]

It is a trivial matter to adjust the linewidth of the axes and plot line in a 2D plot: x <- 1:10; y <- 1:10; par(lwd=2); # axis (and others) linewidth plot(x,y,"l",lwd=6); # plot linewidth Is there anything comparable to this for persp or wireframe? I've tried a number of ways, and the framebox/axes seem to be linked to the linewidth used in generating the

I have looked through the documentation and have not been able to find a way of using an xlim, ylim, or zlim type option on rgl.surface. I know that persp3d has the option, but seems to only be able to expand the axes not reduce them. Is there anyone who has an idea of how to do this? Thank you for your time.

Hello, I am looking for a R routine to fit a function/surface to my data 3d data. I'd like to use the function in a model so something like splines is not applicable. The data are smooth and can provide a plot if helpful. Thanks, Mark

Hi list, I'm struggling with plotting a 3d data set. I have a data frame with x,y and z values. They occur in no particular order (ie x and y are not ordered). However, I want to visualize the data using a contour plot. Now, the x,y and z data going into contour() are supposed to be ordered. My question is: Is their a quick way to re-arrange my data such that it can be fed to contour()?

Good morning, I am Marta Colombo,student at Politecnico,Milan. I am studying local regression models and I am using loess function. My problem is that when I have a loess object I don't know how to display the fitted surface; in fact, while in S when you have a loess object you can see it writing plot(object), in R this dosen't work. Also I'd like to know if there is something like the

Dear R-helpers: I, an entry level R user, wonder how make a 3d scatter plot with both error bars and a flexibly fitted surface. Can anyone eligthen me? Many Thanks in advance. -Sean [[alternative HTML version deleted]]

Hi, there is following issue, which I encounter when doing data analysis. Say we have data in form of the matrix x: > x [,1] [,2] [,3] [1,] 0.1 4 10 [2,] 0.2 5 11 [3,] 0.1 5 12 [4,] 0.1 6 13 [5,] 0.2 4 14 [6,] 0.3 5 16 now I want to do surface plot of x[,3] with respect to axes OX:x[,1] and OY: x[,2] in ascending orders of course. Thanks in advance,

All: Anyone have an idea about how to plot a PLS biplot on the x-y plane under a 3-D surface? Preferably a 3-D surface such as one created with rgl.surface() (meaning, I would love an interactive plot when all is said and done). I have seen examples which combine a 3-d surface with contour plot (e.g.

Hello Is there any R package which can do 3-D splines (reconstruct a surface based 3-D data input) ? Thanks, Zhaoming

Dear List, I am trying to plot a similar graph to attached from minitab manual in R. I have a response Y and three components which systematically vary in their proportions. I have found in R methods/packages to plot ternary plots (eg. plotrix) but nothing which can extend it to response surface in 3-D. Any help appreciated, Tim Carnus [[alternative HTML version deleted]]

Hi I'm interested in doing a anisotropy analysis of some spatial data and I want to do a contour plot of a covariance or variogram surface to visualize the directions of maximal and minimal anisotropy. I know how to do a contour plot :-) but how can I obtain the variogram surface having a geoeas format dataset (X, Y, Z) ? Thanks EJ
