.First.lib
Greetings:
I?m running R version 2.4.0 (2006-10-03) on WindowsXP in a 3 year old DELL
box with 2 gig.
I have successfully created a zipped package, mh1823_2.1.zip, using R CMD
build --binary mh1823.
R CMD build --binary automatically adds a file, mh1823, containing
.First.lib and its default function definition.
I would like to supply my own .First.lib function to create menus when the

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.

require(rcom)

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

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.

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

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

help with my sloppy syntax
R-ians:
After some effort I coerced my code to do what I want but my syntax is a
kludge. Suggestions on more elegant syntax?
par <- NIM.results$par
do.call("Draw.NIM.POD.curve", list(par[1], par[2], par[3], par[4],
par[5], a.hat.decision, .... et cetera ...
It seems that I should be able to avoid defining the variable "par" and then
specifying each of its elements,

invalid \uxxxx sequence while trying to create a package
Greetings, R-Helpers:
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
of R being used.

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.

gsub difficulty

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.

tcl/tk with R
Greetings:
I would like to use tcl/tk with R, and have read "A Primer on the R-Tcl/Tk
Package" by Peter Dalgaard in Rnews, Volume 1/3, September 2001.
Are there more recent do-it-yourself instructions available?
I have been unsuccessful with the example in the tcltk2 package due to a
syntax error.
I think that I have isolated the problem to this code snippet:

R tcl/tk
Friends:
I am a long-time R user, learning tcl/tk, and am tying myself in knots over
something that should be simple.
I want to create a frame and put that frame inside the toplevel frame.
This works (i.e. it places text in col 1, and the corresponding entry box in
column 2) and later frame.2 resides where it should in the toplevel frame.
