[R] how to change the position of xlab in truehist?
Hi, I'm wondering how can I change the position of xlab in truehist. For example, the following code creats a histogram with 4 bins for my discrete data. I want each bin to be labelled as 0, 1, 2, or 3 in the middle, so that it's clear each bin corresponds to each of the discrete case. I was thinking of first delete xlab and then add marks myself, but it doesn't look like it's working. The old label can not be removed by setting xlab= or xlab = NULL. Thanks for your help!

You want to change the value labels on the axis.

Re: [R] help on drawing a tree with ape?
Thank you very much for the help, Ben! As a follow up, is there a way to specify the labels, through the way the text is written, rather than reading the edge positions from the graph? For example, mytree = ((A:51.78,(C:24.6,D:24.6):27.18):40.06,B:91.84):0.0; plot(read.tree(text = mytree)) edgelabels(c(a-b,b,b-d,d,d,a)) would give the graph I want. You may notice that if set a = 91.84; b= 51.78; d= 24.6, the labels I put on each edge is the corresponding lengths in variable form. The way I do it right now need me to first draw the tree and then manually set the labels, and I suppose there should be an easier way to get them by reading the way the tree is written (((A:51.78,(C:24.6,D:24.6):27.18):40.06,B:91.84):0.0;)?

Thanks, Marc and Haris! I didn't know the values of the numbers beforehand, so the scan method won't work, but [^+-\\d.]+ will do! And Haris, I didn't intend to keep the information of which number is B, which is C etc when asking the question, as I had a tedious way to do it (use strspilt and unlist over and over again, after I get the number).

[R] stop unwanted boxes/dialogs in tcl/tk
Hello,
I have a question about tcl/tk: is there a way to stop more
messagers/listchoice/etc. that are set up earlier, but are unwanted later?
for example,
require(tcltk)
ttMain - tktoplevel()
tkwm.title(ttMain,Question)
f.fcn - function(){
t1 - modalDialogOK(Elicitation,What's the LOWER bound of
A1,entryInit=)
t2 - modalDialogOK(Elicitation,What's the LOWER bound of
A2,entryInit=)
t3 - modalDialogOK(Elicitation,What's the LOWER bound of
A3,entryInit=)
}
f.fcn()
When run the function, three dialog box would pop up in sequence. If in the
middle, say, after t2 pop up, I don't want to answer t3, is there a way to
block t3? Close the t1,t2 boxes(even the question main frame) doesn't stop t3
coming up, though it gives a lot of error messages.
Thanks!

Re: [R] help on drawing a tree with ape?

In other words, I don't want to be the one who tells R the command edgelabels(c(a-b,b,b-d,d,d,a)). I'd rather a way R finds out itself.

Hi, All
I'm trying to save the workspace as a Check Point for
possible future come back. The save.image function
works if the whole coding is in a main function:
rm(list=ls())
t = 1
t = t+1
print(paste(before,t))
# [1] before 2
save.image(tt.RData)
t = t+1
print(paste(after,t))
# [1] after 3
load(tt.RData)
print(paste(check,t))
# [1] check 2
As you can see, the value right before I save the
workspace is restored.
However, if I run the saving inside a function, it
seems that it restores to the vale outside the
function rather than the one before the save command:
rm(list=ls())
test.fcn - function(t=1){
t = t+1
print(paste(before,t))
save.image(tt.RData)
t = t+1
print(paste(after,t))
load(tt.RData)
print(paste(check,t))
}
t = 1
test.fcn(t=t)
# [1] before 2
# [1] after 3
# [1] check 1
So it restores the value before the program enters the
function (t=1), though what I really want is the value
inside the function(t=2).
Is there anything wrong with the way I use the
save.image function? Or is there other command I can
use to reach my goal?
Thanks a lot!

[R] disappearing dialog boxes when using tcltk
Dear all,
I'm trying to use tcltk to build a small
user-interface and couter the problem:
It seems that sometimes the dialog box will be
minimized automatically though I want it to be on top
of the screen all the time.
For example, when runing the following code, if you
type in a1, a2, a3, etc when being asked for an
integer, the program is supposed to keeping asking you
until you give an integer. The program runs fine, but
the dialog box is not always on top, and it is
annoying having to maximized it every time (the wierd
thing is that sometimes it is Ok, sometimes it is not.
So I don't know the problem.)
Millions of thanks!
Hua

[R] R book needed
Hi there, I'm looking for advice on a R book that's for somewhat advanced user. I've been using R for a while and can do the basic analysis with no problem. My problem is that for many already existing commands, such as gsub, textconnection, list, etc, I don't use them, simply because I don't know their existence! Can someone recommend a good book that I can refer to and can learn R systematically? Thanks a lot!
