grDevices::convertColor XYZ space is it really xyY?
grDevices::convertColor has arguments 'from' and 'to' which can take on value 'XYZ'. Can someone confirm that 'XYZ' is the same as the CIE chromaticity coordinates that are also sometimes refered to as 'xyY' in the literature? Or are these the CIE tristimulus values? It looks to me like the first case is true, but I would appreciate hearing from one of

The difference between chisq.test binom.test and pbinom
Hello all,
I am trying to understand the different results I am getting from the
following 3 commands:
chisq.test(c(62,50), p = c(0.512,1-0.512), correct = F) # p-value = 0.3788
binom.test(x=62,n=112, p= 0.512) # p-value = 0.3961
2*(1-pbinom(62,112, .512)) # p-value = 0.329
Well, the binom.test was supposed to be "exact" and give the same results
as the pbinom, while the chisq.test

Calculating all possible ratios
I have a data matrix with genes as columns and samples as rows. I want to
create all possible gene ratios.Is there an elegant and fast way to do it in
R and write it to a dataframe?
Thanks for any help.

Multiple Comparisons-Kruskal-Wallis-Test: kruskal{agricolae} and kruskalmc{pgirmess} don't yield the same results although they should do (?)
Hi there,
I am doing multiple comparisons for data that is not normally distributed.
For this purpose I tried both functions kruskal{agricolae} and
kruskalmc{pgirmess}. It confuses me that these functions do not yield the
same results although they are doing the same thing, don't they? Can anyone
tell my why this happens and which function I can trust?

zero variance in part of a glm (PR#11355)
In this real example (below), all four of the replicates in one
treatment combination had zero failures, and this produced a very high
standard error in the summary.lm.
=20
Just adding one failure to one of the replicates produced a well-behaved
standard error.

I don't know if this is a bug, but it is certainly hard for users to

NV43: Native resolution not available on Dell 2007FP
I have a Dell 2007FP monitor. NV43 (GeForce 6600) can not use the native
resolution.
1600x1200 is listed under "DDC gathered Modelines" with the rest of the
info, but then is missing from "probed modes".
I have a secondary card, NV4a (GeForce 6200, PCI). It works with this
card. This card does not show "DDC gathered modelines" at all, and

CKD-Epi formula
Hi all,
I have a question and I do not know If I am at the right place to ask this question. But is there someone that has the formula of CKD-Epi in code in R?
I have tried a lot of loops, but none of the approaches give me the right answer. Is there someone who has this formula coded?
Thank you!

MICE passive imputation formula
Hi all,
I have a question about multiple imputation within the MICE package. I want to use passive imputation for my variable called X, because it is calculated out of multiple variables, namely Y, Z. Let's give an example with BMI. I know, that if I want to use passive imputation for BMI, I can use the following command:

need a solution to an R-problem: consultant available?
I am trying to get confidence bands for a non-linear power function
(y=mx^b). I thought I should be able to figure it out, but can't. Are
there any R consultant? I would be willing to pay some amount of money, but
not sure such consultants exist. I fit power functions to lots of data, and
this would be very useful. I would ideally like to have confidence bands

Measuring and comparing .C and .Call overhead
Further pursuing my curiosity to measure the efficiency of R/C++ interface, I
conducted a simple matrix-vector multiplication test using .C and .Call
functions in R. In each case, I measured the execution time in R, as well as
inside the C++ function. Subtracting the two, I came up with a measure of
overhead associated with each call. I assume that this overhead would be
non-existent of the entire

using cvlm to do cross-validation
Hello,
I did a cross-validation using cvlm from DAAG package but wasn't sure how to assess the result. Does this result means my model is a good model?
I understand that the overall ms is the mean of sum of squares. But is 0.0987 a good number? The response (i.e. gailRel5yr) has min,1st Quantile, median, mean and 3rd Quantile, and max as follows: (0.462, 0.628, 0.806, 0.896, 1.000, 2.400) ?

lme with/without varPower - can I use AIC?
I want to compare the following two models in AIC
(Treat, Spotter are categorial, p is pressure, Pain is
continuous)
PainW.lme<-lme(Pain~p+Treat*Spotter,data=saw,random=~p|Pat,
weights=varPower(form=~Pain))
# AIC= -448
Pain.lme<-lme(Pain~p+Treat*Spotter,data=saw,random=~p|Pat)
#AIC = -19.7
Note the huge differences in AIC, and the estimated power of 6.
