There is a `merge` function. For this use case you would need to first 
parse your expressions so that the LHS was in one character column and 
the RHS was in another character column in each of 2 dataframes. Then 
merge on the LHS columns and `paste` matching values from the two 
columns. You will probably need to learn how to use `ifelse` and `is.na`.

You also need to learn that R is a plain text mailing list and that each 
mail client has its own method for building mail in plain text.
