Because of the issue raised in
https://stat.ethz.ch/pipermail/r-help/2013-November/362896.html, I am
switching to R on Mac OS X (10.6.8) to create some plots. Using
CairoPDF(), however, the commands I use in Windows (7) to select my
fonts don't have any effect on Mac OS X, where the output .pdf
I'm using 'expression()' in R plots in order to get italicized text.
But it appears as if I cannot use Unicode symbols inside 'expression'
outside of ASCII characters. Is there some way I can work around this?
My goal is to get the 'fi' ligature in various labels in my R barplots

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

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:
to a string, pase
it with your term, and then reconvert it to a formula:
update(my.lm,formula(paste(.~.-, my.object)))
There may be a more elegant way via substitute(), but I think this works.
Cheers,
Bert

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.
R version 2.13.1 (2011-07-08)

Some of you might see that there's a tiny mistake in the embedFonts()
call. fontpaths = C/Windows/Fonts should of course be fontpaths =
C:/Windows/Fonts. I fixed this, but it didn't change the fact that
the new .pdf does not have its fonts embedded.

Dear helpers,
I can create a vector with the priority of the packages that came with
R, like this:
installed.packages()[,Priority]-my.vector
my.vector
base boot class cluster codetools
base recommended recommended recommended recommended
compiler
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):
myrepo-getOption(repos)
required by the posting guide.
Most likely this is a limitation of the locale you used (and failed to tell
us about) on the OS you used (...).

Dear helpers,
I'm trying to replace a character with a unicode code inside a data

It's not that a data frame cannot have

funny.g
[1] ḡ
data.frame (funny.g) - funny.g
funny.g$funny.g

I think the problem is in the data.frame code, not in writing. Data.frames
try to display things in a readable way, and since you're on Windows where
UTF-8 is not really

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
Dear helpers,
how can I extract only the values from a row in a data frame? Using
[X,] doesn't do the trick:
data.frame(letters[1:10],letters[11:20])-my.data
my.data[1,]
letters.1.10. letters.11.20.
1 a k
I would like to be able to extract only the values a and k
Great - thanks for the explanation and for the solution using
stringsAsFactors=FALSE in the data.frame function

Hello,
my question is triggered by an actual model I am running, but I will

Take the following regression model:
