In the examples of this R tutorial, we’ll use functions provided by the VennDiagram add-on package for the R programming language. In order to use the functions of VennDiagram, we need to install and load the package first:install.packages("VennDiagram") # Install VennDiagram package ...
Note:Even though the first element of our character string contains the letter “a”, it is not considered as a match. Only exact matches are taken into account. Example 4: Similar Functions to match The R programming language provides several functions similar to match(). Two of the most ...
Even the R language supports the creation of user-defined functions. The user-defined functions demonstrate the actual need of the programmer. Thus, as per the specific need, the users can go for these user-defined functions. Once the user-defined functions are developed then from the next sec...
Introduction to R Programming The R programming language was developed in the early 1990's by Robert Gentleman and Ross Ihaka of Auckland University. It was named R in part because of its creators, but also as play on the programming language on which it was based: the S statistical ...

Every example uses real data and includes step-by-step explanations of the figures and their programming. The open source software R is an established standard and a powerful tool for various visualizing applications, integrating nearly all technologies relevant for data visualization. The basic ...

In R programming language, by default, assigns the data type of FACTOR to every character column. This means that the values in the column are treated as categories. However, sometimes it may be necessary to consider these columns as character strings instead. To do this, you can set the ...
The factory design pattern is used when we have a superclass with multiple subclasses and based on input, we need to return one of the subclasses. This pattern takes out the responsibility of the instantiation of aClassfrom the client program to the factory class. We can apply a singleton ...
