Hm. Google tells me that kernel function is in stats package which comes with base installation and is invoked when you start R.

Please need help to finalize my code
What do you *mean* "when you want to use the kernels".
WHICH kernels?
Use to do WHAT?
In your browser, visit cran.r-project.org
then select "Packages" from the list on the left.
Then pick the alphabetic list.
Now search for 'kernel'.
You will find dozens of matches.

Aide pour finaliser ce code
Hello.
Here is my R code. I used the functional data . Now I need to use the
functional data by applying the kernels instead of the xi, yi functions.

fisher.test() gives wrong confidence interval (PR#4019)
The problem occurs when the sample odds ratio is Inf, such as in the
following example. Given the fact that both upper bounds of the two 95%
confidence intervals are Inf, I would have expected that the two lower
bounds be equal, but they aren't.
x <- matrix(c(9,4,0,2),2,2)
x
# [,1] [,2]
#[1,] 9 0
#[2,] 4 2

How odds ratio is computed in fisher.test()?
I'm wondering how odds ratio is computed. I thought that it is
(n11/n12)/(n21/n22), but it is not what fisher.test() computes. Could
somebody let me know?

help needed with printing multiple arguments as vectors, not matrices
**
I am using the following way to get p-values from fiser exact test.
However, I do need to print for each pair the values "n00, n01, n10, n11".
How can I print that as a table and not a matrix as below along with the
p-value? Any help will be greatly appreciated
fish <- function(y, x) {n00 = sum((1-x)*(1-y)); n01 = sum((1-x)*y);
n10 = sum(x*(1-y)); n11 = sum(x*y); a =

help for R code
Good morning dear administrators,
Please help me to code this code in R.
I use in this file the redescription function ? which by making a scalar
product gives a . You can also choose instead of the redescription function

for loop
HI,
You can do this in many ways:
dat1<-read.table(text="
med1,med2,med3????
?1,0,1??????
0,1,1???
2,0,0
",sep=",",header=TRUE)??
#1st method
library(reshape)
dat2<-melt(dat1)
dat3<-aggregate(dat2$value,by=list(dat2$variable),sum)
?colnames(dat3)<-c("name","sum(n11)")
?dat3
#? name sum(n11)
#1 med1??????? 3
#2 med2??????? 1
#3 med3??????? 2

Hi,
I have a R output that looks as follow:
Rad:0
Rad1:2
Rad3:3
I want to make a new matrix that looks like : sample size is 2400
Variable n11 n12
Rad 0 2400-0=2400
Rad1 2 2400-2
Rad3 3 2400-3
Thanks a lot for your time and help:)

HWEBayes, swapping the homozygotes genotype frequencies
I evaluated the Bayes factor in the k=2 allele case with a "triangular"
prior under the null as in the example in the help file:
HWETriangBF2(nvec=c(88,10,2))
[1] 0.4580336
When I swap the n11 entry and n22 entry of nvec, I received totally
different Bayes factor:

using axis with newline characters
Wondering if I missed anything or if that's a problem with R:
I want to have many x axis tickmarks and labels such that it makes sense to put them on multiple "lines".
The newline character seems to be ignored though for axis labels:
plot(1:33, axes=F)
axis(1, 9, 9)
axis(1, 11, "\n11")
axis(1)
# whereas
title("one\ntwo")
works as I expect it to work.

Fastest way to do HWE.exact test on 100K SNP data?
Hi everyone,
I'm using the function 'HWE.exact' of 'genetics' package to compute p-values of
the HWE test. My data set consists of ~600 subjects (cases and controls) typed
at ~ 10K SNP markers; the test is applied separately to cases and controls. The
genotypes are stored in a list of 'genotype' objects, all.geno, and p-values are
calculated inside the loop over all

help needed for HWE.exact in library "genetics"
Hi,
I have a genotype data for both case and controls and would like to calculate the HW p-value. However, since the number of one genotype is 0, I got wired result. Would someone help me to figure it out? Or confirm it's right? Thanks a lot.

Developing functions
Without trying to understand your code in detail let me just
assume you are trying to create a matrix, ret, whose i,j-th
entry is some function, f, of row i of X and row j of X.
In that case this should do it:
apply(X,1,function(x)apply(X,1,function(y)f(x,y)))

Is there any multivariate regression function to combine all variables from a dataset?
Hi everybody,
I've been looking for a function that combines all variables from a
dataset because I need to do multivariate regression.
If we have linear regression with an expression like f(x) = a0 +
sum(ai*xi) what I want to do is something like f(x) = a0 + sum(ai*xi) +
sum(sum(bij * xi * xj)) + sum(sum(sum(cijk*xi*xj*xk))) + ...
So I need a function that combines all the values from

which() vs. just logical selection in df
Hi Dr. Snow, & R-helpers,
Thank you for your reply! I hadn't heard of the {microbenchmark}
package & was excited to try it! Thank you for the suggestion! I did
check the reference source for which() beforehand, which included the
statement to remove NAa, and I didn't have any missing values or NAs:
sum(is.na(dat$gender2))
sum(is.na(dat$gender))
sum(is.na(dat$y))

logwatch
Hi All,
I need to be able to make sense from my shorewall logs.
I have installed logwatch and it is mailing me reports but the level of
detail is just not there. I have set the detail variable to High=10 but
I get entries only from the DNS service about denied updates. What am I
getting wrong? Tom, will you be kind enough to send me your logwatch
config files?
Thanks in advance.

Size of R user base
I have been trying to determine the size of the R user base, and was
asked to share my findings with this mailing list. Although I still
don't have any definite estimate of this number, I do have some
interesting and indicative information:
