LAPACK in R
2 messages · xiaoping Jin, Brian Ripley
You can't do this. Some of LAPACK is included in the lapack module, but that is not a part of R that is always loaded, and the code has been corrected. Similarly you cannot easily use compiled code in another package. What's so hard about linking your own code against your system's lapack library?

Hi, Now I am writting a R program, which calls a C program by using .C function. I like to use some matrix calculation functions provided by R package in my C program, for example, Cholesky decomposition. When I read "write R extension", it saild "the header file R_ext/linpack.h contains BLAS, LINPACK functions included in R. But we know LAPACK is better than Linpack. Is it possible to use functions from LAPACK. I also saw R_ext/lapack.h in src/r_ext directory. How to use this header file? I have checked "matrix" package. There it used functions from lapack c++ . How to use those information in my C program? What I should do? Hope you can help me out!
