If you are replacing an unknown quantity of text, such as a whole paragraph, the R command is very appropriate.
However, if you're replacing a small quantity of text, a word, 3 letters, etc, there are other commands that will help your editing more precise.
r replaces one single character by another
s replaces one character by an indefinite number of char.
cw replaces one word, etc.
If you have a particular requirement, let us know.
