The function ‘str_detect’ is to detect the presence of the words, and then fill the row accordingly. It totally depends on your dataset to make these necessary categories in the new columns, just modify these commands for your dataset of interest. library(dplyr) ## ## Attaching package:...

Before you run the examples, you’ll need to run some code to import the case_when function, and also to create some data that we’ll work with. Import dplyr The case_when function is part of thedplyrlibrary in R. Having said that, you’ll need to importdplyrexplicitly or import the...

We’ll make use of thescholarpackage to get the data. The primary author used in the package vignette is Albert Einstein, but he doesn’t have any co-authors on Google Scholar; so we’ll use my data instead. library(scholar) library(dplyr) ...
Benchmark Function – Dplyr Onto the fun stuff now! The goal of this section is to write a function that reads one year’s worth of Parquet files from disk and performs some sort of aggregation. We’ll keep things simple and only calculate the basic statistics – number...
If it is 400 and above, some sort of error occurred. You may need to use the if else statement about whether to further proceed into the code depending upon the status code you recieved from the server, as you don’t need to further run your program after you have got an error. Use...
