This function stacks the two data frames on top of each other, appending the second data frame to the first. For this function to operate, both data frames need to have the same number of columns and the same column names. While base R does do grouping operations, I find them to be slightly less intuitive/flexible than when using the data.table or dplyr packages, so I'll stick with those two for the processing here (and leave you to determine which if either you wish to use, and then adapt your processing to do it group-wise). The rbind() function in R is used to merge data frames by rows and is very useful when dealing with a large amount of data.
