Two questions that was not always clear for me [sorry for posting to this list :\]:

Q1) when cabling, is the color order important? like:
straight cabling:
A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown
could be eg.: like this??

Possible bug with chromatic adaptation in grDevices::convertColor
...??? clr <- t(col2rgb(rgb.in)) / 255??? clr.out <- convertColor(clr, "sRGB", "sRGB")??? rgb(clr.out)??? ## [1] "#CCCCCC" "#EEEEEE"
??? convertColor(clr, "sRGB", "sRGB", "D65", "D50")??? ## Error in match.arg(from, nWhite) :??? ##?? 'arg' must be NULL or a character vector
This appears to be because `grDevices:::chromaticAdaptation` expects the whitepoints to be provided in the character format (e.g. "D65"), but they are already converted by `convertColor` into the tristimulus values.? After applyi...

DOE in R?
...have seen the answer to (in SAS) in
order to make sure I would have gotten it *right*.
There are 5 factors: 4 are quantitative with three levels each and 1 is
qualitative with two levels.
Factor and levels:
Intro: 0, 1.99, 2.99
Duration: 6, 9 ,12
GOTO: 3.99, 4.99, 5.99
Fee: 0, 15, 45
Color: Red, White
In order to screen these factors, I would want to get a design where I could
evaluate all main effects, all first order interactions and the squared
terms of Intro, Duration, GOTO and FEE (for example Intro*Intro).
Looking for the D-optimal design.
Is this something that R can provide?

graphics backgrounds from gray to white in png()
Hi,
I'm trying to make a png file of a histogram. I would like a white
background in the final product but end up producing a gray one, despite
setting what I think are the correct parameters. Suggestions for how to
properly set a white background would be welcome.
Thanks in advance,

recode() function results in logical output, not factor output
Dear R Users:
I have race-ethnicity groups identified in the factor variable Ethnic_G.
I need to collapse Ethnic_G into a new variable with only two factors, 1 (White, non-Hispanic) and 2 (Minority).
As seen in the code and output below, the recoded race-ethnicity variable is put into logical format, not factor format.
I've used library(car) and the package was updated.
Any ideas on how to fix this problem would be apprecidated.
Thanks in advance!...

Import in R with White Spaces
Hi,
I have a simple question about importing data, I would be very grateful if
you could help me out.
I have used read.csv(file name, header=T, sep=",") to bring in a csv file I
saved in MS Excel.The problem is I have white spaces in the middle of values
(not in the column names), and this messes up the column entries. Since I
have many many files that I am importing and I have spaces in all of them, I
was looking for a way to avoid going into all of them and changing the white
spaec to, for example, an underscore.

Newbie: Barchart Gray with White Grid?
...(probably, there's a simple way
to do what I'm working toward).
R's statistical functions are coming along easily enough, but graphics
seem to be a little tougher for me, probably because I'm used to
working in SigmaPlot. As an exercise, I tried to create a gray bar
chart with white grid overlay, like the one on page 128 of Tufte's
"Visual Display of Quantitative Information." I figure this would
cover a lot of the basic techniques that I'll need for "real" work. I
got as far as having a gray bar chart (I was working within hist(),
mostly) with...

strip white in character strings
...ames of the files. They are
country-specific and the element mycurrentdata[1,1] contains this
information.
So what I do is something like this:
pdf(file=paste(mycurrentdata[1,1], ".pdf", sep=""), width=...etc)
The only problem I have is that some of the country names contain white
space (e.g., "United Kingdom"). This is no problem for generating the
pdf plots but it may become problematic during further processing (e.g.
incl. the plots in LaTeX documents).
Is there an easy function to strip white space out of character strings
(similar to the strip.white=TRUE...
