Converting a matrix to a dataframe: how to prevent conversion to factor
Colleages
I am running R 2.1.0 on a Mac (same problem occurs in Linux). In
some situations, I have mixed text/numeric data that is stored as
characters in a matrix. If I convert this matrix to a dataframe, the
numeric data becomes factors, not what I intend.
TEXT <- paste("Text", 1:4, sep="")
NUMBERS <- 10 + 4:1
MATRIX <- cbind(TEXT,

regular expressions
Dear list,
I have the following text to parse (originating from readLines as some
lines have unequal size),
st = c("START text1 1 text2 2.3", "whatever intermediate text", "START
text1 23.4 text2 3.1415")
from which I'd like to extract the lines starting with "START", and
group the subsequent fields in a data.frame in this format:

classes/types. My common fields are:
id

plotting labels (not values) on xy plot
I have 2 vectors, x and y and have done an xy plot.
I want to plot the label (name?) of the vector on the plot rather than the
value.
text(x,y, labels = x)
gives me the value of x.
text(x,y, labels = labels(x))
gives me something like c("text1","text2"..) plotted for each point
text(x,y, labels = names(x))
gives nothing
print(x) gives me

Searching for Enumerated Items using str_count() from the stringr package
Hi all,
I have a large number of text strings to search for enumerated items.
However, I am receiving this error message even though I thought that I
properly escaped the special character closed parenthesis:

How to translate string to variable inside a command in an easy way in R
I want to write a function that get 2 strings y and z and does the following
R command.

collapse argument on paste
One gets a different response when abbreviating collapse= in
paste? In the second case, it appears to be acting as if " + " is just
another argument to be pasted.

Does anybody know how in xyplot to put the legend title on one line with the

put the title text in front of the plotting symbol.

Combining plaintext and plotmath expressions
I searched the archives and did not find a solution, so I pose this question to those well-versed in the use of plotmath and expressions.
I have a list of strings in an external CSV file which I wish to use sometimes as plot axis labels and sometimes as plot titles. These strings combine plaintext and a few mathematical expressions (Greek letters, subscripts). Moreover, I sometimes need to

buggy HTML from nested lists w/ paragraphs
I ran into a weird problem while writing my own little guide to
Markdown (using Markdown, of course). The document is mostly made of
list items in nested ul's. As I neared the end, I found (via
MarsEdit's preview) that in place of two sections of content,
Markdown had begun to generate gibberish strings like this:

par(las=.) gives wrong "adj" for mtext() (PR#726)
For R Version 1.1.1 and R-devel (Linux)...
Sorry, there's no time to fix myself now
{e.g., after starting a new device} :
par(las=3); plot(1:10); par(las=1) ; mtext("mtext")
Gives a left-adjusted (as for adj = 0) mtext,
even if par("adj") is still 0.5
Note that I'm also not convinced that mtext() should follow par("las")

Updated the xml code to be more object-oriented
I changed the code to be more prototype-esque, and created a class
called XMLDoc. I may add more functionality to it later, hence the more
generic name, but you do something like this to convert XML to a hash:
XMLDoc = Class.create();
Object.extend(XMLDoc.prototype, {
initialize: function (xmlDoc) {
this.element = xmlDoc;
},
asHash: function () {
if (! this._xmlHash) {
