Is there a way to vectorize this? [with correction]
** Sorry to repost. I forgot to include a function necessary to make
the example work **
I apologize up front for this being a little long. I hope it's
understandable. Please let me know if I need to clarify anything.
Several months ago I wrote a series of functions to help me take my R
analyses and build custom reports in html files. Each function either
builds or modifies a string of

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

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:

transforming a badly organized data base into a list of data frames
Dear R-ers!
I have a badly organized data base in Excel. Once I read it into R it

Unexpected behavior with abbreviation of an argument to paste
R 2.15.1
OS X
Colleagues,
I encountered the following unexpected behavior today:
The following command yielded the expected result:
paste(c("TEXT1", "TEXT2"), collapse="|")
Result:
[1] "TEXT1|TEXT2"
However, abbreviating "collapse" by even one character:
paste(c("TEXT1", "TEXT2"), collaps="|")
yielded the

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

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

Searching for Enumerated Items using str_count() from the stringr package

Shared Columns in an STI
I have a an STI table which acts_as_tree, that has a large number of
classes/types. My common fields are:
id

with 4 more text fields, I could cover most of my classes if I could
redefine the name of the field like this.

Layout Issue ...
The following program represents the basic layout of my application. The
problem I have is that the panel, and thus, the grid does not resize
when the window width is expanded.
Also, I would like the entire grid to be displayed without the

Fast way to call an R function from C++?
Hi,
I'm looking for a most efficient way to call an R function from C++ in a
package. I know there are two functions (`R_forceAndCall` and `Rf_eval`)
that can do the "call" part, but both are slow compared to calling the same
function in R. I also try to use Rcpp and it is the worse one. Here is my
test code:
C++ code:

always on top. I tried a custom key with key=... and text=... but I can't
put the title text in front of the plotting symbol.
I am looking for the following layout of the legend, on one line:
