[Rd] ALLOCATE in a FORTRAN subroutine

Hi Martyn,

Many thanks for your answer. If I make it short : 
we can, once we know how to do it, 'drive' R from within FORTRAN for example to do a 
  Myarray = seq(0, mydimension) 
in R once we have compute mydimension in FORTRAN. Is that correct ?
If yes : it's too 'complicated' for the time I am hired (I mean I have been hired to do FORTRAN code not to learn R !).

Second question : for what I have understood in r_exts, it's more 'efficient' to translate R routines in C rather than in FORTRAN (speed must be the 'same', but there are a lot more possibilities in C for the programmer) : right ? I do not know why my customer (client ?) wanted to translate some R routines in FORTRAN. May be it's by accident (in my humble opinion they even don't know about C). If you confirm this fact, I'll speak about C with my customer because we are at the very beginning of great works (great amounts of work ?) and I don't matter, I am also a skilled C programmer !!

I hope you understand what I want to say, english is not my natural language !

Thanks again and best regards.
