[R] Warning message with aggregate function

[Bartjoosen]

If I use your code, I don't get the error.
Maybe you stripped your code to create a minimal, self-contained,
reproducible code?

Perhaps in your original code, you store the result of the aggragate
function in a dataframe of a different size than the results?
