Subject: Re: [R] Why Does R Print out strange record?
The convention on this email list is to always reply to the list, not
just the person who replied to you.
Many people comment on the same questions with interesting different
perspectives.
Start with two things to read.
1. the posting guide linked at the bottom of each email on the list.
2. The introductory manual at system.file("../../doc/manual/R-intro.pdf")
Specifics: almost everything in R is vectorized, meaning you usually
do not need explicit loops.
I don't use yahoo email so I don't know how to set it to plain text.
I am sure it is possible.
do a web search.
