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

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

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 all, I'm trying to debug some fortran 95 code that I'm bringing in with a dyn.load(). I'm compiling a number of files using g95 on intel linux w/ R 2.1.0. The .so file loads without complaint, but when I try to call it I get a seg fault. I was hoping I could get a core dump in order to get some more clues about what is going on, but no luck. I'm relatively new to fortran

I've got a 4x4 matrix of points from a 2-way ANOVA I'd like to plot. The x,y correspond to the treatment groups and look like this ((1,1),(1,2),(1,3),(1,4),(2,1),...). The z is the 4x4 matrix. How can I get persp to grid the x,y axis with only the numbers 1-4 on both? Regards, Joel Bremson UC Davis Statistics Dept.

At last, simple addition in R is now fast and easy!!! They said it could never be done, but they've never heard of Fortran. In order to add two numbers in R before you had to type: > 7 + 3 It was tedious to type and several hours could pass as you waited for your return value. So, imagine the excitement around your lab or office when you type in:

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

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, 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

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

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 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, I have a working package for linux, including fortran 95 code compiled with g95, that I need to port to OS X. The package works on Linux and seems to load on the Mac, but when I try to run a function that calls C or Fortran I'm told that the symbol is not loaded. I'm developing via a shell account on an OS X system, I don't have access to a desktop. The set up is: R
