If you can delete the quote in the file ress, that is better.

matrice.

Solution: convert 'res' to data.frame.

Hi,
I would love an easy way to extract elements from a list.
For example, if I want the first element from each of 10 arrays stored
in a list,
Lst[[1:10]][1,1] seems like a logical approach, but gives this error:
Error: recursive indexing failed at level 3
The following workaround is
Try
sapply( Lst, function(m) m[1,1] )
Also note that to subset a list, you just need Lst[ 1:10 ] and not
Lst[[ 1:10 ]] (note the double square brackets).
Regards, Adai

Suppose ri were already defined as in the example below.
Then panel.qrect is a bit harder to define although with
work its possible as shown below:
rectInfo -

matrix(runif(4), 2, 2),
matrix(runif(4), 2, 2))
ri - function(x, y, ..., rect.info) {
This will determine where the overlaps are and delete them. You can
add some more code to determine which ones you want to delete.

x$lower - x$Mass * (1 - 5e-6)
x$upper - x$Mass * (1 + 5e-6)
# create a matrix for determining overlap by adding 1 at the lower
38 matches
