The R Core Team has released the new version of R programming language. The source code for the major update, i.e., R 3.4.0 and binaries for Windows, MacOS, and Linux can now be downloaded from
CRAN website.
It is obvious that there have been many improvements and additions in this new version. The most significant improvement is made in JIT byte-code compiler. Now, it will compile the top-level loops before they are run. Also, on first or second use, all the functions will be compiled. This literally means that the JIT compiler is now by default enabled at level 3, which will improve the performance and efficiency of the program.
Other performance improvements include faster sorting of number vectors (thanks to the radix-sort algorithm), quicker computing of tables with missing values, faster processing of long strings while using str function etc.
