Hi Julia:
I am sure that you will find many useful resources as you attempt to learn
R.
If time permits, please look at the Tegrity-based video that Ive prepared
for my students:

Hi,
im working in R but honestly i don t know how to apply the formulas in my
problem, can someone give some help?
I already learn how we use the formulas but im not understanding the main
issue in my problem.

You can't really judge a book by its cover, and in this case not even
the cover is presented to us. But judging by the author's
Julia,
I can vouch for the 'Statistical Analysis in R'. Very good book, I learnt R
from it. The other one to look at is Spoetry. It solves a lot of problem for me.

Hi Julia,
I'm also a newcomer to R and to this listserv (in the past two weeks). One
book that was recommended to me, and has been extraordinarily helpful in
learning how to really make use of R, is "A Beginner's Guide to R", which
focuses on data entry/import, data manipulation, functions, and p
Dear Julia,
Welcome. It is good that you wish to learn more about R.
R has certainly become very vast in the last few years. Do you wish to
learn R for a particular reason (financial analyses, multivariate,
prediction/classification, genetics)? You might get more targeted
reading materials, b

Hi Julia,
I would really recommend reading a book on R. A good option might by the
"Introductory statistics with R" by Peter Dalgaard, or the MASS (Modern
Applied Statistics with S) book. The advantage of a book is that it
presents a coherent overview, saving you time to wade through the
enor
hat best meets your requirements.

Hi All,
I am making a serious effort to try to learn R, but one hurdle I am facing is
that I need to "see" the data as I walk through the examples in the packages.
For instance, many examples on the web start by a command like data("wines").
How can I actually view what the dataset looks like

Thanks Berwin. You're correct in that I meant the R Language
Definition. Well, it may be a draft but I read it for the first time a
few months ago and
it was very enlightening so, whether it's a draft or not, I highly
recommend it. ( but not for total beginners. The R-intro is better for

a quick follow-up:
e = new.env()
e$a = 1
names(e)
# NULL
names(e) = 'a'
# error in names(e) = "foo" : names() applied to a non-vector
this is surprising. names(e) 'works', there is no complaint, but when
names<- is used, the error is about the use of names, not names<-.

Hi Ira:
For your first question, under the hood of R, names<- is actually a
function so , when you do that, you need to say names(a)[2] rather
than names(a[2]). why this is is tricky and I wouldn't do it justice if
i tried to explain it. it's best if you do ?"names<-" at an R prompt and
read t

Why doesn't the 2nd name change to "too"?
