This is a follow up to my question from yesterday. I want to do in R what is called a "3d scatter plot with drop lines" in S-PLUS. Basically, it's a 3dscatterplot with lines connecting the x-y grid to the z points. The lines give a better perspective on the shape of the data surface. How to? Joel Bremson UC Davis Statistics

Hi, I have a class called "spss" containing prepared info from an SPSS file. >... >class(ret) = "spss" >return(ret) The function that returns this defined in a file that I source into R. Also in that file is a function matSummary.spss. I think I ought to be able to call >matSummary(ret) to run the function, but only >matSummary.spss(ret) will work. What

I want to plot some 3D points on top of the grid produced by persp(). On 2/22/01, Paul Murrell <paul at stat.auckland.ac.nz> wrote in R-help: > In S-Plus, persp() returns a value that can be used to transform 3D > locations to 2D, but this sort of thing is not (yet) available in R. But persp() does return something (in R-1.5.1): a 4x4 matrix which in the C code is called the

Is it possible to run Fortran 95 code from R? I don't think so, but hopefully someone can prove me wrong. Here is the test I tried: A little fortran 95 subroutine: subroutine allloc() real, dimension(:, :), allocatable :: a integer :: n n = 10 allocate(a(n,n+1)) end I then compiled: >g95 -c allloc.f >R CMD SHLIB allloc.o Here is what happens when I try to dyn.load it in R 2.1.0

Hi all, I'm porting a package that I've worked on for OS X to Cygwin/Windows. This package requires a Makefile. My question is, how can I find out (or what is), the link command? Here is the OS X Makefile: RLIB_LOC=${R_HOME} F90_FILES=\ class_data_frame.f90 \ class_old_dbest.f90 \ class_cm_data.f90 \ class_cm.f90 \ class_bgw.f90 \ class_cm_mle.f90 \ cme.f90 FORTRAN_FILES=\ dgletc.f

Hi, I have an array of 2d node locations and an array triangles, and would like to plot something like a image or persp. An example of doing it with rgl is: library(ncdf) library(rgl) # wget http://www.maplepark.com/~drf5n/extras/teapot.nc teapot<-open.ncdf("teapot.nc") z<-get.var.ncdf(teapot,"tris") l<-get.var.ncdf(teapot,"locations")

I'm not looking for an answer here, this is just a report of a peculiar event I've observed and can reproduce. I'm developing a g95 (20050129) compiled package on windows xp pro using R-2.1.1, and gcc-3.4.2 (mingw special). An older version of the F95 package compiled and ran without problems. The new version of the package includes extensive changes in the code. The package has a

Hi, I'm having a problem with spss.read reversing my factor input. Here is the input copied from the spss data editor: color cost 1 2.30 2 2.40 3 3.00 1 2.10 1 1.00 1 2.00 2 4.00 2 3.20 2 2.33 3 2.44 3 2.55 For color, red=1, blue=2, and green = 3. It's type is 'String' and >out=read.spss(file) >out $COLOR [1] green blue red green green green blue blue blue red red

Dear all; Does anyone know how to add grid lines to a persp plot? I've tried using lines(trans3d..) but the lines of course are superimposed into the actual 3d surface and what I need is something like the plot shown in the following link: http://thermal.gg.utah.edu/tutorials/matlab/matlab_tutorial.html I'll appreciate any ideas Thanks PM

Hi all, Thanks to all who offered advice on using F95 in R. Now I'm trying to compile a test package using gfortran, Linux 2.4.21 and R 2.1.0. I was able to successfully compile and use a test F95 routine by setting my environment variables as follows in bash: export PATH=~/bin/:$PATH export F77=gfortran export LD_LIBRARY_PATH=~/bin/irun/lib export GFORTRAN_STDIN_UNIT=-1 Now I'm

Dear R-users, is it possible to add a second plane to the persp()-plot? I couldn't find any hint on that in the news archive... I'm using R.1.4.1 for Windows.

Dear List, I am trying to draw a rectangular plane using the persp function, however I can't seem to get it to work. I want the length along x1 axis to be between 1 and 3 and the length along the x2 axis to be between 1 and 4. All z values for x1 should be equal (say, z=1) because this is a plane, not a cube. Below is my current code. Any help is appreciated Thanks in advance dxc13 x

Hello list. I very often need 3d scatterplots, and use scatterplot3D quite a lot. I am trying to modify persp() to plot scatterplots, and make use of the theta and phi arguments that persp() offers. I am having some difficulty passing the correct arguments to persp(). Here is my function so far. Much of it is copied from the persp() manpage. points3d <- function(x,y,z,

Hi all, I'm making an animation of a rotating persp plot of some data. It's easy, really: I just plot the persp in a loop over the theta parameter, saving each plot, and then chain them together with ImageMagick (as suggested on Paul Johnson's R-tips page). But... when you run the animation, because each graph is individually re-scaled, the image is not the same size in each

I have this data set that both x & y are ordered vectors of length 600 & 700 respectively; z is a 600 by 700 matrix whose entry z[i,j] is either a missing value (indicated by 'NaN') or a real number between 0 and 1. The contour function contour(x,y,z) gives me a blank picture. I guess the reason is that most of z-entries are missing, only less than 1% are non missing.

Hi all, (Originally posted to r-help) I'm porting a package that I've worked on for OS X to Windows. The package is written in F95 so I need to compile it with gfortran and link it with gcc4. I've been trying to build an R with gcc4 without luck so far. If there is a binary of such a thing info would be appreciated. This package requires a Makefile. My question is, how can I find

Hi all, If I write v = vector(mode="numeric",length=10) I'm still allowed to assign non-numerics to v. Furthermore, R figures out what kind of vector I've got anyway when I use the mode() function. So what is it that assigning a mode does? Joel
