How to do a Join and a Loop corectly using R

Question

I have two sets of data that have a column mean_wage in common, but they are described differently.

First one as 1 (wage), 2, 2.4 ... and the other one as 1256.7 dollars. Because I'm looking at different years I have to make a wage adjustment, so I find it easier to work with salaries this way (1256.7).

How can I create a new column that loops the wage?

Example:

Data_Frame <- data.frame (
  Training = c("Enginner", "Lawyer", "Welder", "Teacher", "Police Officer","Street Sweepers"),
  Mean_Wage = c(4, 6, 1.2,2,2,1),
  Scholarity_years = c("Undergraduate", "MSc", "High School", "Undergraduate", "High School","High School")
)

# Print the data frame
Data_Frame

Data_Frame2 <- data.frame (Mean_Wage = (1256.7))

Data_Frame2 

I would like to create a new column that contain the function 1256.7 * 1, 2, 3, 2.4...

I tried to bind cols in my original file and got this error

Can't recycle ..1 (size 12) to match ..2 (size 231456...
Backtrace:

1. dplyr::bind_cols(Data_Frame, Data_Frame2)
