speeding read.table
R 2.15.1
OS X
Colleagues,
I am reading a 1 GB file into R using read.table. The file consists of 100 tables, each of which is headed by two lines of characters.
The first of these lines is:
TABLE NO. 1
The second is a list of column headers.
For example:
TABLE NO. 1
COL1 COL2 COL3 COL4 COL5 COL6 COL7 COL8 COL9 COL10

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

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)?

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:
SOMEWORDWITHNOSPACES
any number of spaces and/or tabs
(
any number of spaces and/or tabs
integer
any number of spaces and/or tabs
)
Examples include:

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

Colleagues,
I just took advantage of the function:

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))

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:

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")

As you can see, all contain "SOMETHINGCOMMON" and the position varies. But, I don't know what that "SOMETHINGCOMMON" is.

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.

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:

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:

where XX is the total number of pages.
