adding "Page X of XX" to PDFs
Having read all of the replies, it seems there are solutions for the
question and the OP points out that some solutions such as making the
document twice will affect the creation date.
I suspect the additional time to do so is seconds or at most minutes so it
may not be a big deal.
But what about the idea of creating a PDF with a placeholder like "Page N of
XXX" and after the file has

adding "Page X of XX" to PDFs
You could easily omit the Page X of xX, but leave the timestamp
Then add Page X of XX programmatically using pdftools or some similar pdf
command line tools.

adding "Page X of XX" to PDFs
OS X
R 4.3.1
Colleagues
I often create multipage PDFs [pdf()] in which the text "Page X" appears in the margin. These PDFs are created automatically using a massive R script.
One of my clients requested that I change this to:
Page X of XX
where XX is the total number of pages.
I don't know the number of expected pages so I can't think of any clever way to do this. I

Newbie - Scrape Data From PDFs?
Hi Scott,
I have never done this myself but I read something recently on the
r-help distribution that was related.
I just did a quick search and found a few hits that might work for you.

Identifying special characters in a text file
Colleagues
R 2.10.1 on a Mac
I read in textfiles using readLines, then I process those files, then I use R to execute another program. Occasionally those files contain characters other than letter / numbers / routine punctuation marks. For example, a bullet (option-8 on a Mac) triggers the problem.
Although R can read and process those characters, the other program cannot so I would like to

Probing a function
R 2.12.2
Windows 7
Colleagues,
I just took advantage of the function:
readWindowsShortcut
in R.utils. It accomplished my goals and I was interested in learning its inner workings. So, I typed the function at the command line (without arguments or parentheses). R returned:
function (...)

Help with complicated regular expression
Colleagues,
I am using R (2.9.2, all platforms) to search for a complicated text
string using regular expressions. I would appreciate any help you can
provide.
The string consists of the following elements:

any number of spaces and/or tabs
(
any number of spaces and/or tabs
integer
any number of spaces and/or tabs

Examples include:

Finding the common portion of strings

I have a set of text objects in the form (I am showing 3 of what is more likely to be 20 or so):
OBJECTS <- c("abcSOMETHINGCOMMONegf", "xSOMETHINGCOMMONyz", "SOMETHINGCOMMONnme")
As you can see, all contain "SOMETHINGCOMMON" and the position varies. But, I don't know what that "SOMETHINGCOMMON" is.

Timezone problem with 3.4.2

Thanks for pointing this out. I did a default installation of R. Does this mean that I need to reinstall from the command line?

Registered / trademark signs
Colleagues,
What is the easiest means to embed a:
? (registered)
or
? (trademark)
sign in text in a graphic. I would like to use mtext and avoid plotmath, if possible. Ideally, the sign should be superscripted but I can easily sacrifice that.
Optimally, I need a solution that works in both OS X and Windows (? XP) and with R versions ? 2.11
Thanks in advance.

Applying "toupper" to only portions of text strings
Colleagues
Assume that I have a vector containing some text strings, some of which contain a particular character. I could like to apply "toupper" to the text before the character. For example (in this case, "|" is the particular character):
ORIGINAL:
TEXT <- c("aaaa", "bbb|cc", "|ddd")

Package recommendations for outputting table with cell formatting
Will this need to be done many times? If not, it might be just as easy
to apply conditional formatting to cells after they're already in
Excel.

Printing special characters
R 4.2.2
OS X
Colleagues
A file that I have read includes strings like this:
"EVENT ? 30 sec"
When I include the string in a graphic using:
mtext(STRING, ?)
it appears as:
"EVENT ... 30 sec"
Is there a simple work-around (short of reformatting all the strings, then using plotmath)?

Problem with geterrmessage()
Luke
Thanks ? I revised the code to:
ERRORMESSAGE <- try(source(USERSCRIPTFILE, local=T), silent=T)
print(ERRORMESSAGE) now returns:
$value
[1] 0
$visible
[1] FALSE
Not clear what to make of that.

Adding margin text to lattice graphics
Colleagues
I am learning lattice graphics (R 2.12.2; OS X). Several days ago, I inquired about adding margin text to lattice graphics. Jim Price offered a useful reply, suggesting that I add:
page = function(page) grid.text('words', x = 0.5, y = 0.01)
to my call to the function. The entire function that he suggested was;

Deleting a column in a dataframe by name
Colleagues,
Hopefully a simple problem: I want to delete a column with a known
name from a dataframe. I could write:
FRAME <- FRAME[, names(FRAME) != NAMETODELETE]
or
FRAME <- FRAME[, !names(FRAME) %in% c(NAME1, NAME2, ETC)]
Is there some simpler means to accomplish this?

Newbie - Scrape Data From PDFs?
Hello,
I?m new to R and am using it with RStudio to learn the language. I?m doing so as I have quite a lot of traffic data I would like to explore. My problem is that all the data is located on a number of PDFs. Can someone point me to info on gathering data from other sources? I?ve been to the R FAQ and didn?t see anything and would appreciate your thoughts.

Recursive concatenation
Colleagues,
I want to create the following array:

I recall that there is a trick using "c" or "paste" permitting me to
form all combinations of c("A", "B", "C") and 1:3. But, I can't
