function to determine to which class/category a value belongs to?
Hi all,
I''ve got a simple contingency table produced with table(), and the upper and
lower quartiles (quantile25 and quantile75) for the same dataset.
Is there a function that tells me in which category does the value of the
quartile falls into?
for example:
tabsp <- table(fam$I[fam$I>0])
1 3 6
6 1 1
and for the cumulative frequency distribution
tabcum <- cumsum(tabsp)

problem accessing complex list data frames
Hi all.
I am currently attempting to build a list of sparse matrixes. That I have
already achieved, by
> vmat <- list()

How I am trying to select those elements from the list where the column e.g.
999 is not null. I can do this for one of the sparse matrices with

Amount of writes during index creation
Hi,
I have had a problem report from a Recoll user about the amount of writes
during index creation.
https://opensourceprojects.eu/p/recoll1/tickets/67/
The issue is that the index is on SSD and that the amount of writes is
significant compared to the SSD life expectancy (index size > 250 GB).

Openbsd very slow
Hi
We have a problem with a new server system running OpenBSD 3.6 (macppc). It runs on a vlan which is part of other vlan in a building network infrastructure.
The img0 interface is configured 100baseTX full-duplex as it should be. The speed is disappointing, using samba 2.2.10. Other systems, i.e. four mac's computers exchange data at full speed over that network. All cables are brand new ,

CI with confint
Hello all,
I'm trying to use confint from the MASS package to compute confidence
intervals for an nls object. When I plot the results, however, they don't
make sense - lines cross over the fitted model or just don't match the
data. Code is :

Suggestion.
Hi,
I''m new to the list. I intend to learn about some Linux Networking
features to help myself and others.
I''m looking to control the bandwidth in my office. Basically there are
like 20 computers, a 2MB Adsl Line. And I would love to let them only
use a certain amount of bandwidth. For example let every client use 20KB
of internet bandwidth of the 210KB we can download

I am trying to find a quick way to change some values in a list that are
subject to a condition to be NA. Consider the 3x1 matrix:

And consider the list named v that has 3 elements
