In the example code, we will use themutate(),across()andall_of()functions and the pipe operator,%>%, from thedplyrpackage. The actual conversion is done using a custom function. Example Code: library(dplyr)# This custom function does the actual conversion.con_fn=function(k){return(as.nu...
In the above example, we have passed the 2 as a second argument to the substring() function. so it begins the extraction at index position 2, and extracts the remaining part of the string. Note: The substring() function doesn’t mutate the original string. Similarly, we can also use th...
