Reorder in decreasing order
reorder() is probably the best way to order the levels in a vector
without manually specifying the order. But reorder() orders by default
in an increasing order: "The levels are ordered such that the values
returned by ?FUN? are in increasing order."
Is there a way to do what reorder() does, but order the levels
according to a _decreasing_ order of the values?

Extract names from vector according to their values
Dear helpers,
I can create a vector with the priority of the packages that came with
R, like this:

Extract rows from a matrix according to value in column
Dear helpers,
I'm trying to extract certain rows from a matrix according to the
values the rows have in a certain column. I've been googling for a
while without result.
Here's a reproducible example of a matrix (and the one I was playing
with initially):

gsub() with unicode and escape character

update() ignores object
Hi all,
I'm extracting the name of the term in a regression model that
dropterm specifies as the least significant one, and I'm assigning
this name to an object. However, when I use update(), it ignores this
object. Is there a way I can make it not ignore it? A reproducible
example is below:

embedFonts() does not embed fonts?
Dear helpers,
I'm trying out the embedFonts() to embed fonts into my pdf files.
However, when I inspect the new pdf with a program designed to look
for embedded fonts, I see that the fonts have in fact not been
embedded. Below are my calls.

Support writing UTF-8 output in Windows
As recently discussed on Stack Overflow, R for Mac OS and Ubuntu (so
probably all Unix systems) can correctly write files with UTF-8
encoding, but R for Windows cannot:

I strongly suggest that R for Windows should support this feature in
upcoming versions.

Export Unicode characters from R
Dear helpers,
I am not able to export Unicode characters from R. Below is an example
where the Unicode character is correctly rendered as long as I am stay
within R. When I export it, the character appears only with its basic
code, and the same happens when I import it back into R . I'm using R

PDC: Logging out from Windows XP SP2 takes a long time
I have samba set up as primary domain controller, and have problems with
my Windows XP SP2 machines. Logging in is quick, but most of the time
(nine out of ten times) the logout process takes a long time - I do end
up rebooting, but once I let it stay and it took a whole hour before it
was logged out. It seems to act the same way for all users.

Row percentages for a table object
I an stumbling on something that is probably very simple, but I cannot
see the solution. I have an object generated by the table () function
and want to recompute this table so each cell represents the
percentage of the corresponding row sum.
Of course a dedicated function can be written (which I have done),
containing the necessary loops etc., but there should be a simpler
way. I'd

template homedir confusion
Hi,
I have set up Samba 3.0.0 with ADS integration. It works fine, with a
workaround for a small oddity.
I use template homedirs like this:
template homedir = /home/%D/%U
On a soon-to-be-retired server running 3.0a19, I have a directory LOCAL
(as in LOCAL.DOMAIN.NAME) containing the homedirs - this works as
expected from the output of "getent passwd", which shows the homedirs of

How to extract p value from the lmekin object obtained by fitting mixed model with function lmekin() in package coxme?
Hi, R experts
I am currently using lmekin() function in coxme package to fit a
mixed effect model for family based genetic data. How can I extract the p
value from a lmekin object? When I print the object in R console, I can
see the p value and Z value are just over there. But I can not extract them
by the coef() function. kinfit$coefficient$fixed (kinfit is the name of the
lmekin object)

Syslinux + integrated flash disk
Quick summary: Syslinux stops at "Boot failed". Which, from a quick look at
the raw disk image, seems to indicate that the boot sector loads but it fails
to load the .sys loader.

that is not NT embedded) into a set of Compaq Evo T20 48/64 for a while now.

Extract time only from POSIXlt object
How can I extract only the time component from an POSIXlt object?
For example if I try the following it still returns both the date and
time...
>as.POSIXlt(tr.date[1])
[1] "2010-10-18 21:46:53"
>as.POSIXlt(tr.date[1],"%H:%M:%S")
[1] "2010-10-18 21:46:53"
round and trunc don't help... is there an "as.Time" equivalent to as.Date
?
Thanks,

Missing information in source()
Dear R-help,
I am running a Mac under Sierra, with R version 3.4.2 and RStudio 1.1.383. When running head () or tail () on an object in a script using source (<script name>) nothing appears in the output file, but if I use these commands in the normal R window the normal output appears.
What am I doing wrong?

Tranferring R results to word prosessors
I have just started looking at R, and are getting more and more irritated
at myself for not having done that before.
However, one of the things I have not found in the documentation is some
way of preparing output from R for convenient formatting into something
like MS Word. An example: If you use summary(lm(....)) you get nice
output. However, if you try to paste that output into the word

Transferring results from R to MS Word
R-users
At the moment I am teaching a course on the use of R for data analysis.
Part of course requirements involves the transfer of results from R to
something that resembles the APA (American Psychological Associations)

R2HTML library, with a call like this:

Is R portable?
Recently I came across an interesting web site:
http://portableapps.com/. The idea is simple, this is software that
is possible to install and run on some type of USB memory, a stick or
one of these hard disks. I can think of a number of situations where
this could be handy. In addition memory sticks are getting cheaper
and more powerful by the day.

Permutation test, grouped data
I am perfectly aware that this question is not an R question, at least
not yet, but I have not succeeded in finding what I want in other
ways, so ...
What I am looking for are two algorithms, preferabley in Pascal, but
other languages may do. For (a) systematic (complete) permutations
for grouped data with unequal group sizes, and (b) random permutations
for the same kind of data. I know
