R Programming

The head() and tail() function in R are often used to read the first and last n rows of a dataset. You may be a working professional, a programmer, or a novice learner, but there are some times where you required to read large datasets and analyze them. It is really hard to digest a […]

URL: https://www.progressiverobot.com/strsplit-function-in-r/ As a programmer, you may need to work on tons of strings. You will perform concatenation and splitting of them very often. There comes the strsplit() function in R. In a previous article, we have discussed the [paste()](/community/tutorials/paste-in-r) function to concatenate the strings. Now, let's see how we can split a [string vector](/community/tutorials/vectors-in-r) […]

URL: https://www.progressiverobot.com/min-max-in-r/ Finding min and max values is pretty much simple with the functions min() and max() in R. You know that we have functions like [mean](/community/tutorials/find-the-mean-of-values-in-r), [median](/community/tutorials/find-the-median-in-r), [sd](/community/tutorials/find-standard-deviation-in-r), and mode to calculate the average, middle, and dispersion of values respectively. But did you ever thought of a function which gives you min and max […]

So, let us begin!! 🙂 What is Normalization? Feature Scaling is an essential step prior to modeling while solving prediction problems in Data Science. Machine Learning algorithms work well with the data […]

URL: https://www.progressiverobot.com/substring-function-in-r/ Substring() function in R is widely used to either extract the characters present in the data or to manipulate the data. You can easily extract the required characters from a string and also replace the values in a string. Hello folks, hope you are doing good. Today let's focus on the substing function […]

URL: https://www.progressiverobot.com/outlier-analysis-in-r/ Hello, readers! In this article, we will be focusing on Outlier Analysis in R programming, in detail. So, let us begin!! What are outliers in data? Before diving deep into the concept of outliers, let us focus on the pre-processing of data values. In the domain of data science and machine learning, pre-processing […]

URL: https://www.progressiverobot.com/sum-in-r/ Let's learn how to find the sum of the values with the help of the sum() in R. In this tutorial, we will try to find the sum of the elements of the vector. The syntax of the sum() function is = sum(x,na.rm=FALSE/TRUE) [Vector](/community/tutorials/vectors-in-r) is the easiest method to store multiple elements in […]

URL: https://www.progressiverobot.com/paste-in-r/ Using the paste() function in R will be straight and simple. In this tutorial let's see how we can use paste() to concatenate the strings and values. paste(): Takes multiple elements from the multiple vectors and concatenates them into a single element. Along with paste() function, R has another function named paste0(). Yes, […]

URL: https://www.progressiverobot.com/unique-function-r-programming/ The unique() function in R is used to eliminate or delete the duplicate values or the rows present in the vector, [data frame](/community/tutorials/data-frames-in-r-programming), or [matrix](/community/tutorials/matrix-operations-in-r) as well. The unique() function found its importance in the EDA (Exploratory Data Analysis) as it directly identifies and eliminates the duplicate values in the data. In this […]
