Programming languages like C, C++, and Java, variables are declared as data type; however, in Python and R, the variables are an object. Objects are nothing but a data structure having few attributes and methods which are applied to its attributes. There are various kinds of R-objects or ...
In programming, data type is an important concept.Variables can store data of different types, and different types can do different things.In R, variables do not need to be declared with any particular type, and can even change type after they have been set:...
In programming, a string is a set of characters. For example,'A'is a single character and"Apple"is a string. You can use single quotes''or double quotes""to represent strings. In general, we use: ''for character variables ""for string variables ...
A mechanism provided by R programming through which elements of a vector can be arranged in a particular order, usually facilitated by but not just limited to the order() function that assists in sorting the elements either in ascending or descending order, as required, with the normal use of...

These types of variable names are not allowed in most languages, but R is flexible in that way. Furthermore, the example goes to show a common theme around R programming: it is so flexible that if you're not careful, you will end up shooting yourself in the foot. It's not too rare...
