need help with plotmath and/or plotting unicode characters
R 4.2.3
OS X
Colleagues
This should be easy -- but not for me.
I want to plot text similar to this:
N ? XX: YY
where XX can be either 1 or 50 and YY is an integer
I envision that there would be two solutions:
UNICODE: If I can generate "?" via unicode, the problem is solved:
mtext(side=3, paste0("N ", UNICODE, " ", XX, ": ", YY))

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.

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

Impact of cex changing as a function of mfrow
R 2.15.1
OS X (MLion)
Colleagues,
I am aware that changes in mfrow / mfcol in par() affect cex (from help: In a layout with exactly two rows and columns the base value of ?"cex"? is reduced by a factor of 0.83: if there are three or more of either rows or columns, the reduction factor is 0.66).
I generate a multipage PDF in which mfrow varies such that cex is impacted. This affect

string width calculation
Colleagues,
I am trying to create a PDF document in which I use margin text with two different fonts. The resulting text might be:
XXXXXyZZZ
where X and Z are one font and Y is the other.
My plan was to do this in the following manner:
mtext("XXXXX ZZZ", cex=2, adj=0.5, family=SOMEFONT)
mtext("Y", cex=2, adj=??, family=DIFFERENTFONT)
My question regards how to calculate

Constructing arguments for plotmath
Colleagues,
I am encountering difficulty adding formatted text to a graphic. Specifically, I want to add a superscript in the middle of a text string but I would like to format the text string on the fly. The commands:
plot(1,1)
ARG <- bquote('TEXT'^'\u00ae')
mtext(ARG, line=-2, side=1)
yield the desired output.
However, my goal is to paste together a string, then pass

printing a data.frame without row numbers
R 4.2.3
OS X
Colleagues,
I am printing a large number of tables using the print command. A simple example is:
print(data.frame(COL1=1:5, COL2=10:6))
The result in this case is:
COL1 COL2
1 1 10
2 2 9
3 3 8
4 4 7

I would like to print the table WITHOUT the row numbers:

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

Examples include:

Probing a function

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 (...)

Package recommendations for outputting table with cell formatting
R 4.0.2
OS X
Colleagues
I have the unfortunate need to create a large number of tables (destined for a Word document). I need to color cells depending on the contents, e.g., blue if the value is < 0.5, red if the value is > 1.5.
If the output went initially to Excel, that would work; outputting directly to Word would be even better.
I expect that several packages can accomplish this. I

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;

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")

Subsetting a list
Colleagues,
I have created a list in the following manner:
TEST <- list(c("A1", "A2"), c("B1", "B2"), c("C1", "C2"))
I now want to delete one element from the list, e.g., the third. The
command
TEST[[3]]
yields (as expected):
[1] "C1" "C2"
The command
TEST[[-3]]
yields:

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.

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.

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?

strsplit and sapply
Colleagues,
I have some text:
TEXT <- c("a", "bb;ccc", "dddd;eeeee;ffffff")
I want to retrieve the portion of each element before the first
semicolon. I can split each element using strsplit:
SPLIT <- strsplit(TEXT, ";")
This yields:
> SPLIT
[[1]]
[1] "a"
[[2]]
[1] "bb" "ccc"
[[3]]
[1] "dddd"
