gsub[] R Function
The base R gsub[] function searches for a regular expression in a string and replaces it. The function recieve a string or character to replace, a replacement value, and the object that contains
the regular expression. We can use it to replace substrings within a single string or in each string in a vector.
When combined with dplyr’s mutate[] function, a column of a data frame can be cleaned to enable analysis.
