[R] First read (was: Re: Looping and paste)
It's very seldom that I disagree with
Bert, but here is one time.
I don't think An Introduction to R is
a suitable first read for people with
little computational experience.
Better (I modestly suggest) would be:
http://www.burns-stat.com/pages/Tutor/hints_R_begin.html
which includes some other references.
'Hints' is imperfect and incomplete but
it suffers slightly less from the curse of
knowledge than a lot of other R documentation.

Dear R helpers
I'm trying to make up some labels for plot from this vector
BndY-seq(from = 18900,to= 19700, by = 50)
using
Ylab-for(i in BndY) {c((paste(i, to ,i+50,mN)))}
but the vector created is NULL
However if i use
for(i in BndY) {print(c(paste(i, to ,i+50,mN)))}
I can see the for loop is making the labels I'm looking for but not sure
on my error in assigning them to a vector
Thanks in advance

I must agree with Patrick here. The 'Intro to R' may be appropriate
for someone already versed in statistics and/or programming, but it is
hardly useful as a first read for the neophytes.
Better (I modestly suggest) would be:
http://www.burns-stat.com/pages/Tutor/hints_R_begin.html
To chip in, the first two chapters of Fox and Weisberg (2011) make for
an excellent introduction to R programming. It's gentle, but also
covers many of the difficulties and misunderstandings that one would
encounter in R.

Re: [R] First read (was: Re: Looping and paste)
Pat:
1. Thank you for this. Having not read your tutorial, but based on
what I know of your other efforts, I am sure that you are correct. Is
there a link to this on CRAN somewhere so I can refer to it in future
(too lazy to search myself)?
2. Thank you also for your continuing contributions to R
documentation. I know this takes a lot of work and you do it well.
Would that more R learners would read them -- there would be a lot
less RTFM type queries on r-help.
Best,
Bert
