[R] read.socket - Strange strings. How to force sub to remove all occurences of a pattern?

[Henrik Bengtsson]

Hi, here's some classical questions to you; what's your system and
what version of R are you using? Could you give a workable code
example how you connect to the Apache server? Is the server public so
others can test your code?

About sub(): you're looking for gsub().

Cheers

Henrik Bengtsson
