Problems with variable types.

I have problems in a dataframe variables types.

[OFF] Nested or not nested, this is the question.
Hi,
sorry by this off.
I'm still try to understand nested design.
I have the follow example (fiction):
I have 12 plots in 4 sizes in 3 replicates (4*3 = 12)
In each plot I put 2 species (A and B) to reproduce.
After a period I make samples in each board and count the number of
individuals total (tot) and individuals A and B (nsp). Others individuals
excepts A and B are in total of

predicting values from multiple regression
Hey List,
I did a multiple regression and my final model looks as follows:
model9<-lm(calP ~ nsP + I(st^2) + distPr + I(distPr^2))
Now I tried to predict the values for calP from this model using the
following function:
xv<-seq(0,89,by=1)
yv<-predict(model9,list(distPr=xv,st=xv,nsP=xv))
The predicted values are however strange. Now I do not know weather
just the model does not fit

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

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:
WORD ( 123 )

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

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)?

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

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]]

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?

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;

I just took advantage of the function:

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:

Colleagues,
I am printing a large number of tables using the print command. A simple example is:

Problem with geterrmessage()
Luke
Thanks ? I revised the code to:
ERRORMESSAGE <- try(source(USERSCRIPTFILE, local=T), silent=T)
print(ERRORMESSAGE) now returns:

[1] 0
$visible
[1] FALSE
Not clear what to make of that.

Understanding contents of packages
Colleagues
During the transition to R3.0.0 (OS X), one of the packages that I used -- SASxport -- did not work until I used the "type=source" option in install.packages.
This led to an adventure:
1. I downloaded the package source: SASxport_1.2.4.tar.gz
2. in the SASxport/R folder, I found all the functions that are part of the package.
I became interested in whether I could
