The R programming language is basically command-line (interpreter-type) programming. We can perform any type of mathematical and statistical calculation, including data management analysis and graphics in the command line. The
R command window is known as the R console, where the command and the results are produced upon execution of a given command.
Here is a very basic example of using the R console:
> (44/55)*100  80 > log(25)  3.218876 > log10(25)  1.39794 > exp(0.23)  1.2586 > 453/365.25  1.240246 > 1-5*0.2  0 > 1-0.2-0.2-0.2-0.2-0.2 # An interesting calculation  5.551115e-17
Using the R console, we can perform any type of calculation, but we always need to preserve the code to reproduce the result ...
