The terminal renders it where you left the cursor..

Should I learn Python or R?

R and Python are both open-source programming languages with a large community. … R is mainly used for statistical analysis while Python provides a more general approach to data science. R and Python are state of the art in terms of programming language oriented towards data science.

How do you escape in R?

There are other characters in R that require escaping, and this rule applies to all string functions in R, including regular expressions:\’ : single quote. … \” : double quote. … \n : newline.\r : carriage return.\t : tab character.
