How would you use regular expressions in data visualization
What are Regular expressions?
Regular Expressions are also called as Regex. It is defined as a series of components which designates the search pattern in a set of data. These patterns are utilized via multiple string-searching algorithms to FIND or FIND AND REPLACE functions upon strings, and for input authentication (Assam, & Evergreen, 2013). Every team of strings is needed for a significant purpose. For example, Boolean OR is used for unraveling alternatives like Grey/Gray. Parentheses are utilized for describing the scope as well as the operator's precedence. Other methods
are quantification and wildcard which are used for different purposes.
Why are Regular Expressions useful?
In the case of specifying patterns, Regular Expressions are the most useful methods. All the patterns match a cluster of strings, consequently, regular expressions assist to define a particular identity for a set of strings. Not only that, regular expressions help to describe the programming languages. The specification of the regex is known as the example of a recursive definition. The main work that regular expressions do is that it can eliminate any extraneous data from a set of data, confirming that emails are threaded correctly and all the duplicates are detected appropriately. It also can describe a user's search criteria according to a pattern for matching his requirements.
How would you use regular expressions in data visualization?
Data visualization is one of the most useful and vital methods for industries. It is because the world has
become data-centric. But before data is being presented as a form of visualization, it should be analyzed before being presented. Data analysts and scientists need to go through multiple techniques and methods. It is where regular expressions become useful to them. Regular expressions take place as vital text patterns that can be automated for searching as well as relocating characters inside the strings of texts. Thus, it helps the analysts and scientists to handle a large set of data in a small amount of time. R language uses regular expressions to ease the work process of data scientists. With the help of R, the data scientists can analyze data and visualize the results (Miller, 2017).
There are several packages in R that make the task easier and the findings can be represented in a structured pattern. At the same time, R helps in documentation as well. Not only that, but R also helps to design an interactive dashboard using R shiny. I would use the regular expressions in the above-mentioned ways.
