R statistics r-base
R is a state-of-the art system for statistical computing. I note that it is now in extras-devel but with an indication of missing components.
If anyone has downloaded r-base-core and used it, the community would appreciate any comments regarding downloading and the risks involved. (Is libprint-utils an insuperable problem?) Thanks P.S. It is being worked on -- I just have to wait. See http://wiki.maemo.org/User:Tanner and wish him well. Quote:

It is working very well with the emacs-ESS package. |
Re: R statistics r-base
First, thanks for working on this. I enabled extras devel and saw two entries: r-base and r-core-base. I was able to install r-core-base but r-base will not install whether I use the gui or apt-get. It says there are unmet dependencies (the R base libraries - the ones that are recommended are listed as broken - r-cran-boot, r-cran-cluster, etc. - 12 packages althogether). I can start R in xterm but library() shows there are no packages installed. R needs this basic packages to function.
Is there a way to fix this? It would be great to be able to run R natively on the N900 (rather than using Debian or ssh'ing to another computer. |
Re: R statistics r-base
After playing with R, I see that I do have basic functionality. For example hist, qqnorm, mean, plot etc. work. But I cannot install packages either using either R CMD INSTALL or using install.packages.

Re: R statistics r-base
Installation is (well was, when I last looked a couple of years ago for the N800) troublesome as a compiler is required on the device. This could probably be overcome now.

Re: R statistics r-base
I have only just installed r-base-core (n900 fremantle). My first
thought was that it is surprisingly fast to fire up (the other stats package I could easily install was Incanter, which runs in Clojure, and is 10-20 fold slower to load and run). First problem I encountered was the pager was set to /usr/bin/pager so that help() did not work: /etc/R/Renvironment needs more felicitous choices ('more' works OK for me). The graphics demo worked beautifully, as do a random set of example()'s I ran. Installing R packages from source is a challenge on many platforms, because of the toolchain required. It seems difficult to get a maemo Fortran -- the octave port used f2c AIUI. My usual g95 does not extend to arm, let alone armel, and I am not looking forward to making a gfortran cross-compiler from source for my own uses. Nevertheless, at least the recommended packages should be available as binary packages. just 2c, David Duffy. |

Re: R statistics r-base
Tom Tanner has gfortran 4.4 (and gcc 4.4) packaged up at
http://n900.tannerlabs.com, so this is what he used to make his version of R. Using this, I successfully compiled and installed R-2.12.0 along with all the recommended packages. This takes up 55 MB (including the online docs), and seems to be working fine. Cheers, David Duffy. |
