R CMD check
Dear r-devel members,
I tried to build R packages on a PC running Windows XP but experience
problems. However, it is ok when there is no inst directory in a package.
Any help would be appreciated.
The following is an example,
C:\work>R CMD check VR_7.2-19.tar.gz
* checking for working latex ... OK
* using log directory 'C:/work/VR.Rcheck'
* using R version 2.1.1, 2005-06-20

VR (looking for MASS) on OS X
Hey, when did I lose MASS? Anyway, I found the VR package but she's
not compiling on OS X. Any tips? Yes, I have the developer tools
and Fortran. Could someone send me a compiled package?

Calculation of e^{z^2/2} for a normal deviate z
I agree with many the sentiments about the wisdom of computing very
small p-values (although the example below may win some kind of a prize:
I've seen people talking about p-values of the order of 10^(-2000), but
never 10^(-(10^8)) !). That said, there are a several tricks for
getting more reasonable sums of very small probabilities. The first is
to scale the p-values by dividing the

How to determine a subset of a binary strings?
Hi,
I need some neat ways of determing a subset of binary strings. For example,
x=c(0,0,1), y=c(0,1,1), z=c(0,1,0). So x is a subset of y and z is also a
subset of y, but x is not a subset of z.
I tried to search R functions and packages but no hits. Any ideas?
Best,
Jing

Calculation of e^{z^2/2} for a normal deviate z
You may want to look into using the log option to qnorm
e.g., in round figures:
> log(1e-300)
[1] -690.7755
> qnorm(-691, log=TRUE)
[1] -37.05315
> exp(37^2/2)
[1] 1.881797e+297
> exp(-37^2/2)
[1] 5.314068e-298
Notice that floating point representation cuts out at 1e+/-308 or so. If you want to go outside that range, you may need explicit manipulation of the log values. qnorm()

using wildcards in download.file?
Hi,
Do you know whether it is possible to use wildcards in download.file()?
For example:
url = "ftp://abc.com/*.*" # to download all the files in the ftp folder
download.file(url,destfile=...) # does not work, any solutions?
Thanks!

n-th power of a matrix
Hello all,
To calculate the power of a matrix, I used the command "mtx.exp(X, n)", but
there is an error saying "Error: couldn't find function "mtx.exp"". How can
I deal with this problem?

use of buffers in sprintf and snprintf
Hi again,
I realised it is useful to replicate the warnings locally without relying on CRAN automatic check; instead of R(-devel) CMD check --as-cran package_version.tar.gz one can use
R CMD check --configure-args=""
and in my case the WARNINGS were initially given with https://www.stats.ox.ac.uk/pub/bdr/gcc9/README.txt and those specification might as well used in --configure-args

problem for wtd.quantile()
Dear R-users,
I don't know if there is a problem in wtd.quantile (from library "Hmisc"):
--------------------------------
x <- c(1,2,3,4,5)
w <- c(0.5,0.4,0.3,0.2,0.1)
wtd.quantile(x,weights=w)
-------------------------------
The output is:
0% 25% 50% 75% 100%
3.00 3.25 3.50 3.75 4.00
The version of R I am using is: 2.1.0

Where is MASS
Dear List:
I have been using the MASS package until 5 minutes ago. I just updated
some packages from CRAN, something happened and R crashed. I then
started R again and tried to source in some code that calls MASS, but
received an error that there is not a package called MASS.
I then went to install packages from CRAN and MASS was not visible as an
option and I then went to the CRAN website and

read.table
Hi All,
I wonder if there should be one character for quote= in read.table, i.e.,

function (file, header = FALSE, sep = "", quote = "\"'", dec = ".",

I have a file containing the following lines,

pnorm
Dear R list,
I calculated a two-sided p values according to 2*(1-pnorm(8.104474)), which gives 4.440892e-16. However, it appears to be 5.30E-16 by a colleague and 5.2974E-16 from SAS. I tried to get around with mvtnorm package but it turns out to be using pnorm for univariate case. I should have missed some earlier discussions, but for the moment is there any short answer for a higher

use of buffers in sprintf and snprintf
No, that will make it even worse since you'll be declaring a lot more memory that you actually have.
The real problem is that you're ignoring the truncation, so you probably want to use something like
if (snprintf(tempname, sizeof(tempname), "%s.%d", of1name, j) >= sizeof(tempname)) Rf_error("file name is too long");
BTW: most OSes systems have a path limits that

Strsplit with a separator of ||
Hi,
I tried to use strsplit for separating a string with || like
strsplit(string,"\\||") but it returned each single character was separated.
For example:
strsplit("a||bc","\\||")
[[1]]
[1] "a" "" "" "b" "c"
where I want the result to be "a" and "bc".
Any ideas?
Thanks!
