To Start R Studio, click its desktop icon or use ‘lookup windows’ to access the program. It looks like this:

Assignments commonly allow a variable to hold unique values at distinct occasions for the duration of its existence-span and scope. However, some languages (mostly strictly functional) don't make it possible for that sort of "destructive" reassignment, as it would imply improvements of non-community condition. The reason would be to enforce referential transparency, i.e. capabilities that do not depend upon the condition of some variable(s), but deliver exactly the same effects for the provided list of parametric inputs at any position in time.
