R Programming

Hello, readers! In this article, we will be focusing on the concept of rows and columns in R i.e. get the number of rows and columns of an object in R programming, in detail. So, let us begin!! 🙂 Be it a [matrix](/community/tutorials/matrix-arrays-in-r) or a [data frame](/community/tutorials/data-frames-in-r-programming), we deal with the data in terms of […]

URL: https://www.progressiverobot.com/sample-in-r/ Let's understand one of the frequently used functions, sample() in R. In data analysis, taking samples of the data is the most common process done by the analysts. To study and understand the data, sometimes taking a sample is the best way and it is mostly true in case of big data. R […]

If I ask you a question – "Do you use spreadsheets"?, I will immediately get a straight YES. It shows how popular and useful spreadsheets are in day-to-day business operations. If you are an analyst, then spreadsheets are invaluable. You might have used both Excel and Google sheets for your works. There is a good […]

Hello folks, today we will be looking into the applications of the sink() function in R. We are going to try to make connections in multiple formats such as text and [csv file types](/community/tutorials/r-read-csv-file-into-data-frame). Using the sink() function, […]

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 […]

URL: https://www.progressiverobot.com/normalize-data-in-r/ Hello, readers! In this article, we will be having a look at 3 Easy Ways to Normalize data in R programming. 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 […]
