the examples, so may be related to one of the objects scicomp5.model1,

Hi to all
is there any construct to sum
data=data.frame(row1=c(1,1,3,1,2,3,2,2,1,3,4,5,2,3,2,1) ,
row2=c(2,2,1,1,1,2,1,2,1,1,1,1,2,2,2,1) )
Means I would like to get all y of row1 if in row2 of the data.frame is
an x
f.e row1=3 and row2=2
so I would like to get 6
And

No, you cannot have a cycle in Imports / Depends / LinkingTo
otherwise you will run into an the chicken or the egg problem:
That declaration means that the other packages must be loadable on

and
sum(with(data, row1 == 3 row2 == 2))

R can or cannot response immediately depending on the underlying C
sources. If the underlying source code is written carefully enough,
there are more or less regular checks for events such as this one.
If you are using some
I am wondering if there is a CRAN package that includes a utility
function that will rotate file names, in the same sense that
operating systems sometimes rotate log files. Or maybe there's
something in base R.
That is, we have a set of file names, say file1, file2, file3, and
when the
You can try something about like this:
foo - function() {
unlink(file3.txt)
file.rename(file2.txt, file3.txt)
file.rename(file1.txt, file2.txt)
sink(file1.txt)
cat(test file1)
sink()
}
