| == Sobre compilação e pacotes == | |
| R-2.14.0 (and higher) comes with Luke Tierney's byte-compiler installed. Byte-compilation can speed up R computations by | |
| a factor 5, although if your functions are just calls to compiled C code the speedup will be much | |
| smaller. By default, only the required packages are byte-compiled. But if you set (in your bash profile) | |
| export R_COMPILE_PKGS=1 | |
| then all packages will byte-compile when installed. If you set | |
| export R_ENABLE_JIT=3 | |
| then all functions you define in your interactive or batch session will be byte-compiled the first time they | |
| are entered into the workspace (and the same is true for all loops). \\ | |
| It should be noted that some contributed packages have namespace problems when byte-compiled. | |
| R-2.15.0 (i.e. R-devel) has parallel versions of Map() and mapply(). parallel makes fork or socket | |
| cluster and has parallel random number generation. MPI clusters are handled (for now) by passing the | |
| information to the snow package. | |
