wrapper for the Gnu Scientific Library

An R wrapper for special functions of the Gnu Scientific Library. (http://www.gnu.org/software/gsl/). Error forms of GSL functions (_e versions) are used if available. The function naming scheme directly copies the GSL manual except that leading gsl_sf_ and, if present, the trailing _e is stripped: thus gsl_sf_Airy_Ai_e goes to R function airy_Ai(); however, some functions (such as gsl_sf_sin()) retain the prefix to avoid conflicts: a full list is given in help(Misc). Function arguments have the same names as in the GSL reference manual. The package is organized into units corresponding to GSL header files; the .c, .R, and .Rd filenames match the header filenames, except that the .Rd files are capitalized. Functions appear in all files in the same order as the GSL reference manual, which precludes the use of the tidying method given in section 3.1 of R-exts. Documentation is limited to: (a), a pointer to the GSL reference book, which would in any case dominate any docs here; and (b), re-productions of some tables and figures in Abramowitz and Stegun (June 1964).
