Fwd: Re: legend() with option adj=1
Is there a simpler way then the solution to the one that was posted here? I'm
not very proficient with legend, and I don't understand this solution. All
I have is two or more lines on one plot that I want to put a legend on and I
can't figure out how to do it from the examples. Can you give a very simple
example? It does not have to be fancy!! I have never worked with a

calling files of commands in R
Please excuse me if this is a very basic question and I am just
misunderstanding the basic structure of R.
Right now, I am writing everything in a buffer (emacs) and then copying it
into R when it is correct. Is there a way to save a file of commands and
then just type the file name or something in R and have the commands executed
within R?

anova and tukeyHSD
I would like to do a one way anova and then a tukeyHSD. I have three vectors
A,B and C. In a previous help message, I was told to do the following for
the anova:
y = c(A,B,C)
group = factor(rep(a:3,c(7,9,13))) #provided there a 7 elements in A,9 in B
and 13 in C
and then
anova(lm(y~group))
Looking at the tukeyHSD method it looks like it wants the aov method which I
don't understand.

Post Hoc methods for anova in R
Does anyone know of some methods already programmed up ( ie freeware : ) ) in
R for the post hoc methods in anova. Particularly Scheffe's method or
Tukey's?

indexing into a list 2
I didn't explain myself well.
You are right about not needing a list on the right hand side of the equation
below. What I end up with is a list of arrays. Now what i would like to do
is to access the individual elements in the arrays in the list. For example,
when I type, y[[1]], I just get the whole first array. How do I get the
first element in the first array for instance? Is

plot vertical labels along x axis
I know how to print my own labels along the x axis:
plot(1:10,xlab = "My label", axes = FALSE)
axis(1,at=seq(1,10,by=2),labels=c("first","second","third","fourth","fifth"))
Is there a way to make the labels print vertically along the axis rather than
horizontally? (I'm not sure if this is even going to look all right, but I

anova
I am totally confused as to how to use anova. I have three vectors and would
like to use anova on them but I don't understand how lm or glm comes into
play. In matlab, you just give the three vectors. Why isn't it the same in
R?
Any help would be greatly appreciated.

repeating colors in graph 2
I've tried looking at ?colors and ?palette and if I'm understanding it
correctly, I'm supposed to type in (for example) palette(rainbow(13)) before
I type in my plot (of 13 lines) if I want 13 different colors. But this does
not work. Other things that i have tried besides rainbow give me errors.
Am I just doing something completely wrong?

repeating colors in graph
I have a plot with 13 lines and R repeats colors. Is there any way to make R
not repeat colors, or is this just a fundamental limitation on R's part to
say have only 8 colors that it can use?

plots
I have two separate questions.
The first is when I use xlab, the labels on my tic marks disappear. Is there
a way to make them reappear? Also, is there a way to make my own labels for
the tick marks?
My second question is, after I have spent a lot of time getting my plot to
look just right, I want to save it to a file, but the only way I seem to know
how to do it is to first use

indexing into a list
I am trying to make an array of lists. I don't think that I am doing it right
however because I cannot access the individual elements of the lists once I
have created the array of lists. Can someone help?
for(i in 1:3){
y[[i]] = list(name[((i-1)*index+1):(i*index)])

What is wrong with m?
I've been programming in one directory and recently switched to another
directory. It appears that in doing so I've uncovered a problem. My
environment was saving something so that my code would work and now I don't
know how to fix it. I have the following bit of code:

indexList = lst[i]

Splom plot:how to plot with different symbols?
Hi,
Kindly let me know if I posted a wrong question in the forum.
I want to draw a splom plot with different symbols in plot. My command is as
follows:

I don't know how to retain my row labels. I read in a table with row labels,
ie:

circular reference lines in splom
Hello everyone,
I'm stumped. I'd like to create a scatterplot matrix with circular
reference lines. Here is an example in 2d:

colnames(dat) <- c("X1", "X2", "X3")
dat <- as.data.frame(dat)

Putting regression lines on SPLOM
Sorry Folks,
I'm sure I could suss out the answer myself but I need it
soon ... !
1. Given a set of 4 variables X,Y,Z,W in a dataframe DF, I make
a scatter-plot matrix using splom(DF).
2. I do all regressions of U on V using lm(U~V), where U and V
are all 12 different ordered pairs from X,Y,Z,W.
3. Now I would like to superpose the regression lines from (2)
onto the corresponding

Adding axis lines to splom plots
Hi,
I am trying to produce a 30x30 lattice grid. The 30 variables naturally
fall into three groups of ten and I would like to add thicker axis lines
around these to highlight this. However, I can only do this separately,
so far, and I don't know how to superimpose the grid with the thicker
lines (separating the 10x10 groups) onto the overall grid of all 30x30
plots. I enclose a
