Help with ANOVA
...d in either R or statistics, but have been pointed in the direction
of doing ANOVA and then multiple comparisons on the data to give me the
information I need. I was wondering if some of you could help me out. What
I want to do is to do ANOVA on a data set like the following:
ID G1 G2 G3 NG1 NG2 NG3.................
A 4 3 2 5 4 3
B 5 3 5 4 4 2
C 3 3 2 2 4 4
........
There are many more rows and columns, but basically each G or NG equivalent
has replicates and these are found in every A, B, or C. What I want to do
is run ANOVA on this large data set, then be able to use a multiple
comparison...

Passing names of variables to functions

I am still new to R and have a programming question. I have created a
small function which takes a parameter. In the function I want to be able
to refer to the names of the variables sent to the function (specifically
I want to be able to use the name of the variable given to the function in
an output table). For example, in the following (fictional) function I

R GUI For Which User?
I also agree with Philippe Grosjean that there is a need to investigate the
effects of different types of GUIs on software "usability". To do that,
however, there is a need to develop a set of appropriate metrics, and to
understand that the appropriateness of a given metric (and ultimately a given
type of GUI) is likely to be conditional on the type of user.
My sense is that the

re: GUI's for teaching
Hi,
Have you seen the tcltk package? I believe it is a better option than the
one you outline in your message. Why develop a Windows-only GUI? Maybe in a
few years your teaching department will give up Windows for Linux (for the
reasons you wrote about R: it is free, advanced, and adaptable). There is
an article in R News (vol.1, n?3) by Peter Dalgaard on the tcltk package,

Integer vs numeric
Hi the list.
I do not understand the philosophy behind numeric and integer.
- 1 is numeric (which I find surprising)
- 2 is numeric.
- 1:2 is integer.
Why is that ?
