what is "R"? Is it difficult to learn "R"?
zencaroline
Hello,
At your possible convenience, might any expert please kindly answer
my equestions? Thank you very much.
I am suggested to use "R".
1) What is "R"?
2) Is it difficult to learn "R"?
Thank you very much.
Please take care

you'll get their website http://www.r-project.org/. The faq explains
what R is. Basically, it's a statistical programming language. It's
more flexible but more complex and harder to learn and to use than
statistical packages like SAS, SPSS, Stata. On the other hand, there
are a lot of cutting edge techniques available on R that aren't
available anywhere else. It's a good option if you want to experiment
with new techniques, develop your own, or if you're on a low budget.
See http://www.ats.ucla.edu/stat/technicalreports/ for a second
opinion.
Good luck,

R is a free version of S-Plus. If you program in R then you use the
program in S-Plus it works ... usually.
Imho S-Plus is a great statistical package and one of its strength is
the graphical part. The difference is that s-Plus is more near to SPSS
as interface, R to SAS. You can found a lot of specifical techinchs
developed by someone and put at disposition on internet.
Learning R is not too difficult, but it's better to use directely on a
project and learning on the field
The strength of R is being free. I don't know, but I would, if is
comparable to SAS for managing big data set

It depends on the level you would like to use R. On the basic level
no, on advanced yes. According to me it is not very difficult but
has some peculiarities one should be aware of.

It is a regular programming language with some syntactic sugars for
data processing.

R could also be used as a efficient scripting language for
not-that-low-budget systems.

Isn't that originally developed at Bell Labs and now supported by Insightful?

Actually, S was developed at Bell Labs. Insightful has purchased
the rights to the S language.

I did not know that. Thanks you for correcting me.

integrate R into SPSS as well as Python. You can run R programs
within your SPSS syntax that read and write SPSS datasets. The R
output goes in the SPSS Viewer as plain text or pivot tables, and R
programs can read SPSS output (captured via OMS) and use it for
further computation.
There are about 30 apis that SPSS has implemented for use in the R
program within SPSS.
I will be talking about some of this at the upcoming SPSS Directions
conference in Orlando at the end of October (www.spss.com).
HTH,

Why it took you so long to integrate R and Python into your
software?

If you mean a GUI, there are plenty of them for R:

I saw some general info there, Bob, but no links to actual GUIs. The
one I'm aware of is John Fox's R Commander:

others. I'm happy with my command line, so I haven't explored them.

before or are familiar with object oriented programming. A great
reference book, kind of the best basic tutorial I've found is Crawley's
book on an intro stats with R (it's very well written and easy to follow
for any skill level --> I used it as a textbook while teaching stat
computing for non-stat people) he also has the R book, which I recently
bought that has a lot more info, and is still well written. good luck

A vote of disagreement. In my experience it was far easier to learn than
SAS and far easier to manage real data than with Minitab. I found it
comparable to GLIM for difficulty in learning.
