another tcl/tk query
Greetings:
I wish to use a tcl/tk widget to ask for user-selected parameter values. My
widget works ? it asks for and returns to my workspace the stuff I need.
Here is a snippet of my code:
###############################
OnOK <- function()
{
LOG.X <<- as.logical(as.character(tclvalue(log.X.buttonValue)))
LOG.Y <<- as.logical(as.character(tclvalue(log.Y.buttonValue)))

non-ascii characters in TclTk
Greetings, R-Helpers:
A year ago or so I was able to use the non-ascii character ? in my TclTk.
(You can type it on Windows as <alt>0226) I can use something like
expression(hat(a)) elsewhere in R, but I seem to be doing something wrong
when I try that syntax in TclTk. The widget will run but it displays
something frightening like R-call_lang 019C8480 019A7724 where I expected to
see ?.

gsub difficulty
Greetings R-ians:
I know what doesn?t work but I don?t know why, nor how to remedy things.
I have a character string containing "." which I want to replace with " "
gsub(".", " ", file.label) replaces the every character with a blank.
However gsub(".xls", " ", file.label) replaces ".xls" with a blank as
expected.

Which R version created a package?
Greetings, R-ians:
I would like to know which version or R was used to create a given package.
I think I remember seeing that topic discussed recently but cannot find it
among my notes. Can anyone tell me how to determine which version of R
created a package?
Thanks.

Scripting - sort of
Dear R-ians:
I'm running R2.9.2 on a 6 year old Windows XP DELL with 2 Gig RAM and a 3MHz
Pentium 4 chip.
I've written a package using the User Menus Under Windows commands
(winMenuAdd, etc). It works very well.
I have 6 test cases and running any one of them requires many selections
form the menus and some keyboard entry, and it takes me hours to exercise
them all to see

help with R semantics
Greetings:
I'm running R2.6.2 on a WinXP DELL box with 2 gig RAM.
I have created a new glm link function to be used with family = binomial.
The function works (although any suggested improvements would be welcome),
logit.FC <- function(POD.floor = 0, POD.ceiling =1)
{ if (POD.floor < 0 | POD.floor > 1) stop ("POD.floor must be between zero
and one.")

compiled help pages
Greetings:
This should be easy but it isn't.
I have a home-brew package that works fine, with compiled html help pages,
all 150 of them. I want to make a similar package but not from scratch
since only a half-dozen routines are changed. So I created a new directory,
copied the old package into it and changed the name to newSTUFF. I changed
the names of all help pages too, as weill

control L to clear the Rgui screen in Windows
Greetings R-ians:
Searching the Searchable Mail Archives I discovered that ctrl L will clear
the Rgui screen, which is what I'd like to do from a print (or some similar)
statement.
Is there a mechanism to use the ctrl L clear-screen sequence in a script, or
print statement?
Thanks for your counsel.

plotting partial deriviatives
Dear R Helpers:
I am trying to annotate a plot. The following code snippet works, but it is
kind of a kludge since it adds the partial derivative symbols after creating
the plotmath frac(). Is there a more elegant way to write a partial
derivative?
dev.off()
plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015)

HOW to provide a CITATION file?
Greetings, R-ians:
I am sure I am missing something obvious.
How do I provide a CITATION file for my home-brew package, so that it will
be packaged using
R CMD build --binary myPackage?
I have placed a CITATION file in the myPackage directory along with the
DESCRIPTION file, but it is ignored.
Thanks for your guidance.

FW: Can't access CRAN
Dear R-Helpers:
I'm running R version 2.8.1 on a 1 year old HP Pavilion with a AMD Athelon
64 Dual Core Processor 4800+ 2.50GHz chip, Vista Home Premium SP1, and 2 GB
RAM. I can't add packages (even running as Administrator) because I can't
connect to a CRAN mirror.

cannot load package "splines"
Greetings R-Helpers:
I am trying to help a Chinese colleague who is experiencing difficulty
loading my package. He is running WindowsXP and the Chinese version of
R2.8.1.
As you can see from his screen-copy (below), my package is successfully
unpacked but cannot be loaded because splines balks when attempted to be
loaded. Package mh1823 requires package survival, which in turn requires

avoiding a loop?
I have a vector, (not a list)

and would like to convert this into a single string

I can do that with a loop, but isn't there

Dropdown boxes in tcltk and R
Hello,
I'm very much a newbie in R and more so in tcltk so apologies if this
question is stupid. Basically I am trying to use the combobox example
found here:
http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html .
What I want to do is in that example get fruitChoice as a variable in R
in general. When I run that code, however, and the ask for fruitChoice

I am trying to build a package on WinXP, something that I have done before,
but infrequently, and have recently updated both the Rtools and the version

clear screen?
I?ve been using this routine for several years. I?m sorry, I don?t remember
where I got it. It works as it should, viz. it blanks the R console. But
it requires package rcom and now that requires rscproxy.

screen resolution effects on graphics
Greetings, R-Citizens:
I have the good fortune of working with a 19" 1280 X 1024 pixel monitor. My
R-code produces nice-looking graphics on this machine but the same code
results in crowded plots on an older machine with 800 X 600 resolution. In
hindsight this seems obvious, but I didn't anticipate it.
My code will be used on machines with varying graphics (and memory)
capacity. Is
