vlookup in r dplyr

The vlookup function in R can be performed using the dplyr package. Here are the steps involved in performing a vlookup using dplyr:

1. Load the dplyr package: Use the library() function to load the dplyr package into your R environment.

2. Read the data: Read the data that you want to perform the vlookup on using the read.csv() or read_excel() function. Store the data in a variable.

3. Perform the vlookup: Use the left_join() function from the dplyr package to perform the vlookup. The left_join() function takes two arguments - the first argument is the data frame you want to perform the vlookup on, and the second argument is the data frame that contains the lookup values. You also need to specify the columns that you want to match on using the by argument.

4. Save the result: Save the result of the vlookup in a new variable.

5. View the result: Use the View() or print() function to view the result of the vlookup.

Note: Make sure that the columns you want to match on have the same name in both data frames. Also, ensure that the data types of the columns match, otherwise the vlookup may not work correctly.
