Once upon a time, in a land of data and code, there lived a kingdom of R enthusiasts. The kingdom was ruled by a wise king who loved to play with data. One day, the king was working on a dataframe and found that some of the values in one of the columns had typos.
"Oh no!" cried the king. "These typos will surely ruin the analysis and bring doom to the kingdom!"
Just then, a wise old man appeared before the king and said, "Fear not, Your Majesty. I have the solution to your problem. The gsub function can replace the typos with the correct text."
The king was skeptical at first, but he decided to give it a try. He typed in the code, hit enter, and suddenly, the typos disappeared as if by magic!
"Hooray!" cheered the king. "The gsub function is a lifesaver!"
From that day on, the king and the kingdom lived happily ever after, always using the gsub function to keep their data clean and accurate.
The end.
Here's an example of substituting for text in a character string of a dataframe."
df$column_name <- gsub("text_to_remove", "", df$column_name)
