I am sending to this forum as stackoverflow has devolved into sth
pretty bad.
Below code shows how to get what I want in a clumsy way.
cols <- letters[1:4]
a1 <- outer(cols,cols,paste0)
b1 <- a1[!lower.tri(a1)]
X <- matrix(rnorm(80),ncol=4)
colnames(X) <- cols
X <- as.data.frame(X)
XX <- matrix(0

PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.
When I do it with a function I lose the workspace. This is on a
regulated matter and I MUST keep record of all commands/output from the
source script plus the resulting workspace.
Thanks everybody.

BTW is it possible to get the error
Please, help with announcing an error from Rterm:
I am calling R from an Excel VBA and noticed that if there is an error
nothing conspicuous happens. I would like just a popup window when R
cannot finish cleanly. The "ret " value returned from Shell is useless
in determining what happened.
Tha
is how
to submit a second argument to "Close"?
Submitting a second argument to Open works fine as shown by the "0"
below, but neither "1" nor "-1" worked for Close. Very strange.

Hello,
I just discovered that I cannot close the Excel application and task
manager shows numerous copies of Excel.exe
I tried both
x$Quit() # shown in the rcom archive
and
x$Exit()
and Excel refuses to die.
Thank you very much.

hello,
Please help with using sprintf with character variables:
The following does not produce what i intended
foot=function(){
str1=format(Sys.Date,"%Y%m%d")
sprintf("99%-4s%s","nm",str1)
}
I wanted to have "99nm 20071002" as the output.

Dear all,
Does R have any functions for C/Fortran style text formatting when a
number needs to be output right-justified in a fixed length field?
say '%2d %3d %5.3f'
or like python .rjust(n) and .zfill(n)
I can do it paste(), but it is very clumsy.
Thank you very much

is there a straigthforward way to get the holidays for Toronto ?
like the function for NYSE e.g.
the timeDate class says that setting a finCenter will give the right
holidays, but how?
thank you very much.
