howto improve sharpeness of fonts in a jpg-image produced by R ?
Hi.
I've done a standard barplotexample using R1-8.0, redhat8, probably using a
GhostScript-integration.
How can I improve the "sharpness" of the fonts.
See for example the barplot (originally jpg coming from R) which is part of
this screendump:

RODBC and Table views
This question relates to the use of the RODBC package for retrieving data
from a MS Access database. It is quite easy to retrieve data sitting in
tables but is it possible to select from views based on these tables? The
archives do not touch on this point.
sqlTables() lets me see tables and views but only the tables yield data. Do
I need to recreate these views on the R side of the connection?

Saving graphs in formats other than PDF?
I am running R 2.01 on Mac OS 10.3.7. Whenever I save graphs, they are
saved as PDF files. Are there any other file formats to which I could save
my graphs. I would like to directly export my graphs to MS Word, if
possible.
Thank you in advance.

Hi all,
sorry for my english, but I don't speak yours language.
I'm trying to use bart() and rbf(). The package I'm using now is
"BayesTree" and "neural", respectively. I could create the models, but I

Does anyone have such an experience? Any advice is appreciated!

Myth? 21 disk raidz3: "Don''t put more than ___ disks in a vdev"
In a discussion a few weeks back, it was mentioned that the Best Practices
Guide says something like "Don''t put more than ___ disks into a single
vdev." At first, I challenged this idea, because I see no reason why a
21-disk raidz3 would be bad. It seems like a good thing.
I was operating on assumption that resilver time was limited by sustainable
throughput of disks, which
