Here, both the variables - fruit and my_char - are of character data type. 6. Raw Data Type A raw data type specifies values as raw bytes. You can use the following methods to convert character data types to a raw data type and vice-versa: charToRaw() - converts character data to...
Example 1 illustrates how to determine the classes of our variables with the sapply function: sapply(data,class)# Inspect classes with sapply# x1 x2 x3# "integer" "character" "factor" The variable x2 is an integer; the variable x2 is a character; and the variable x3 is a factor. ...
The data in the data frame can be spread across various columns, having different data types. The first column can be a character while the second column can be an integer, and the third column can be logical. The variables or features are in columnar fashion, also known as a header, ...
It is clear that there are two categories, or in R-terms'factor levels', at work here: "Male" and "Female". The functionfactor()will encode the vector as a factor: factor_sex_vector <- factor(sex_vector) There are two types of categorical variables: anominal categorical variableand an...

In this tutorial, you have covered R's variables, rules for defining variables, different types of assignment of the variable along with different kinds of checking the variable types, and removal of the variable. If you would like to learn more about R, take DataCamp's...
