R help - Sep 2008 - removing a word, the following space and the next word

>Hello,
I am hoping for advice as to how I could remove all words immediately 
following the words 'Mr' or 'Mr.' in  a csv file. For example,
the
following phrases are included in lines of text (along with other Mr) 
that could be anywhere in the file: "Mr Jones ate lunch" and "Mr 
Smith was tied".


I want to remove the words Jones and Smith (etc) leaving the other 
text intact.

Any suggestions are appreciated,

regards


Bob

Hi Bob,

I recommend doing some background reading on regular expressions[1]
and using gsub().

Cheers
