ML Estimation Differences with R and SAS
List,
I'm working on fitting a logistic model for a well known dataset (which is
given below in case anyone wants to try to reproduce). I used both R and
SAS to fit the model and have some differences in the parameter estimates.
I'm wondering if R calculates the ML estimates differently. I'm making NO
accusations as to which program is "right or wrong". That is not the

Possible bug with chromatic adaptation in grDevices::convertColor
It appears that the chromatic adaptation feature of `grDevices::convertColor`is broken, and likely has been for many years.? While a little surprising, it is an obscure enough feature that there is some possibility this is actually broken, as opposed to user error on my part.? If it turns out to the latter, I apologize in advance for spamming this list.

Multidimensional contingency tables
How does one ideally handle and display multidimenstional contingency
tables in R v. 2.6.2?
E.g.:

+ perp=c(rep('white',2),rep('black',2),rep('white',2),rep('black',2)),
+ death=rep(c('yes','no'),4), count=c(19,132,11,52,0,9,6,97))

DOE in R?
Hello!
This is not a topic I am well versed in but required to become well versed
in...I welcome any assistance!
Using R, I want to create an optimal design for an experiment. I'll be
analyzing the results with logistic regression or some generalized linear
model. I am thinking that the algdesign package can help (but no idea where
to start?).
I'm presenting an example here that I have

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.

Remove leading and trailing white spaces
I have a character string and I would like to remove the leading and
tailing white spaces. The example for 'sub' shows how to remove the
trailing white spaces, but I still can't figure out how to remove both
trailing and leading white spaces because I can't find any documentation
for what "+$" means or what "\\s+$" means. Maybe its because I don't

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

to do what I'm working toward).

strip white in character strings
Dear all,
I have several datasets and I want to generate pdf plots from them.
I also want to generate automatically the names of the files. They are
country-specific and the element mycurrentdata[1,1] contains this
information.
So what I do is something like this:

The only problem I have is that some of the
