Windows does not come with C or Fortran 77 compilers preinstalled, either. Windows binaries for the free Fortran 95 compilers gfortran and g95 do exist, and I use them daily. <snip> > The Fortran code in R itself is (entirely, I think) > imported from > elsewhere, e.g. from EISPACK or LAPACK or Netlib. > We have little interest > in changing long-established code, and as the recent > thread 'eigen in > beta' shows, everytime we update such code someone > thinks there is a new > bug in R. That is understandable, but it also suggests that defects in code in contributed packages should be fixed before it is "published" and people start to rely on it. The main benefit of the R project is the provision of working software to end users, who do not care about the style of the underlying C and Fortran code. A secondary benefit is that it provides a source of code for statistical algorithms that programmers can incorporate in their own programs. This audience will care about the quality of the code. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
