Is R a compiled language?

I cannot find it anywhere on the Internet (and I do not want to install it). Is R a compiled language? How fast is script pre-writing? Does it do any compilation or just follow line instructions?

In most cases, R is an interpreted language that runs in a read-evaluate-print cycle. There are many extensions for R that are written in other languages, such as C and Fortran, where speed or interaction with native libraries is convenient.

I often rewrote R code in C ++ and ran it 100 times faster. The cycle is especially inefficient in R.

R is usually an interpreted language. However, the compiler package offers bytecode compilation that can improve performance. You can also call compiled code from R.

In terms of how quickly it depends on what you are trying to do and how you are trying to do it. Some cycle operations can be very slow. However, in many cases with well-written code, the performance of R scripts is determined by the speed of the underlying internal C libraries and the read / write speed of system memory, and therefore R is about as fast as everything else.
