How do I compare two data frames in R?

To compare these datasets, simply pass them to the comparedf() function:

1. comparedf(df1, df2) Compare Object Function Call: comparedf(x = df1, y = df2) Shared: 3 non-by variables and 3 observations.
2. summary(comparedf(df1, df2)) Summary of data.frames.
3. summary(comparedf(df1, df2, by = “id”)) Summary of data.frames.
