ansari.test (one tailed)
Hello.
I am probably wrong... I am wondering if it could have a mistake
in the code of the ansari.test function. For me, it seems that the function
do not recover the p value at the correct side of the normal law N(0, 1) when it
use
the normal approximation (presence of ties) in a one tailed test.
Exemple :
quanti<-c(197, 205, 228, 234, 237, 195, 233, 226, 244, 227, 259, 185, 198, 253,

Add on argument in seq()
Thanks for your answer.
The rational behind my proposal is why taking "from" when length.out=1, more than "to" or "NA", or " integer(0) " ?
This question seems basic. But is is not in certain situations, like when length.out = unpredictable positive integer.
And I haven't found in ?seq() the particular behavior of this function when length.out = 1.

Add on argument in seq()
Hi.
I have a problem with the default behavior of seq(), which gives the argument "from" when the argument length.out = 1.
This behavior is annoying when the number of value determine in length.out is not predictable.
Would it be possible to add an argument that propose the median/mean, i.e. (from + to) / 2 when length.out = 1 ? Examples:
> seq(from = 1, to = 11, length.out=1) #

Indeed, as Hadley says, the output of seq must always start with* from*. It
is a sequence starting at *from* and ending wherever the other arguments
cause it to end. A sequence

Add-on argument in sample()
Hi.
I have a problem with the default behavior of sample(), which performs sample(1:x) when x is a single value.
This behavior is well explained in ?sample.
However, this behavior is annoying when the number of value is not predictable. Would it be possible to add an argument
that desactivates this and perform the sampling on a single value ? Examples:
> sample(10, size = 1, replace = FALSE)

Regardless of the value of the other arguments, the first element in
the output of seq() is _always_ `from`.

Millot,
I think the problem with that is that what you propose isn't a sequence
starting at from in any meaningful way, and thus does not satisfy the
contract of the seq function.
Best,

Add-on argument in sample()
Hi,
Special behavior of sample(x, ...) when length(x) is 1 is of course
a bad feature. I think it pre-dates sample.int() which is what people
should use these days if they want the behavior of sample(x, ...) when
length(x) is 1. And because we now have sample.int(), this feature
could in theory be removed from sample(). Unfortunately this would
break a lot of existing code so a warning or some

Thick stripes in the barplot() function
Dear all,
Sorry to bother you, but I didn't find the solution in the R-help archive.
I would like to change the thickness of stripes inside the barplot. Is there any
solution
to do that when using the barplot() fuction and the density option ?
Or is there any other function ?
Thanks very much for your help.
Best regards.
Gael.

Help page of colors() : add a new example ?
Dear all,
May I suggest to add an example in the help page of the colors() function ?
The following code could be useful to easily choose any color from colors() :

## Figure displaying all the 657 built-in color names of colors().

ansari.test.default: bug in call to uniroot?
A recent message on ansari.test() prompted me to play with the examples. This

small bug in ansari.test
The help page for ansari.test() says (emphasis added):
By default (if exact is not specified), an exact p-value is computed if both
samples contain less than 50 finite values **and there are no ties**.
Otherwise, a normal approximation is used.
However, this does not appear to be the case in R 2.4.1 or R 2.5.0. In fact,
even
example(ansari.test)

Ansari vs wilcoxon vs ks test
Hi all,
This is a statistics question, I hope someone out there will be able to help
me.
I have one population (oligonucleotide probes spotted on a Nimblegen array).
I measured "parameter one" (intensity after hybridisation) and I have
selected a subpopulation of the initial (one tenth of the initial) according
to a threshold value.
I now measure "parameter two" of

Porting R
I am trying to get R 1.0 running on the Mac.
The main target is MacX. Anyone else working on that?
For the recent Macintosh system, I am trying to compile R using MachTen.
The R core compiles and runs without any changes, using the Unix make files.
The libraries give some problems, presumably due to handling of shared
libraries. It seems I am missing something to link. Before I spend my time

How to use a 'hidden' function directly?
I would like to be able to use two functions; qansari and pansari
which are found in the
function ansari.test. How can I evaluate these functions
independently? Thanks. --Dale
For example, when I load the function ...
qansari <- function(p, m, n) {
.C(R_qansari, as.integer(length(p)), q = as.double(p),
as.integer(m), as.integer(n))$q

Trying to install R-1.7.1 on a RedHat 8.0 platform, I have a few problems.
