Document Summary
It has a unique feature of vectors (r is vector-based: vectors: is a sequence of data of elements of the same basic type, for example, a sequence of numbers [1, 2, 3, 4, 5] It could also be a sequence of names [sumayyah, abdullah, shah: to start working with r, you need, an editor (r- studio, helps to edit the data, and an interface. Rgui: helps to manage the r environment, the instructions and functions are typed in the console window. It tells r what to do: rstudio is a code editor and helps in, highlighting the codes, automatic bracketing, completes the code. R commands: the most basic function of r is that it calculates, the first number in brackets is the number of the answer, > 3+4+5. [1] 24: to quit or save the screen, type > quit (, r can calculate many values at a time, which is called vector operations.
