...rom another Fortan main program & it does work as expected, so the Fortran works, but my problem has been with the correct syntax for retrieving the output double array from within R. The wrapping Fortran subroutine is defined; subroutine xypos_parallax_r(k,year,ra,dec,ti,t0,tE,alpha,u0,piee,pien,y) k is the number of rows & y an assumed size double array, y(2,*), the other arguments are other input variables for the Fortran. I've tried putting the Fortran function call inside an R function, with this syntax; #Source positions in lens plane under annual parallax xypos_parallax &l...

I've got a big data.frame from which I need to extract data based on a variable number of Id's (InfCode). Until now I've been using the following dull solution as I never needed to search for more than 5 codes. Now my needs have increased faster than my R skills did and I need to call my function with about 25 values for x. There has to be a *apply or even simpler solution which
