aproximate a titration kurve to the measure data.
Halo
i'm studying chemistry, today we made an experiment and i have to draw a
titration kurve for my mess data. we can do it on a mm paper, or we can also
use a programe. people from chemistry recomend "R"
last year i studied civil eng. and we used Matlab, as I see, R ist very
similar to it, but its got other comand...

I've looked in a couple of the classic R texts, the extensions and
developers' manuals, and R help archives, and didn't find a definition. Of
course, I may have missed it.
Thanks in advance. Bryan

auto mounting group shares
I am using autofs to mount user's home and group directories. The
setup works fine for home directories which are mounted after user
logs in. The group shares are also mounted, but user has to manually
do cd or ls command on group shares, e.g.: ls /groups/chemistry will
mount chemistry group share. Is there any way to mount group shares
automatically?
I noticed that after successful login 'some program' performs chdir
(cd) which probably tells autofs to mount home dirs. Which program
does this operation? Is there any way to do this for group shares

Where are usages like "== 2L" documented?
Gurus:
I keep seeing other people?s code that contain ideas like
If (x == 2L)
X[-1L]
X - 1L
I have some idea of what?s going on, but where is the use of concepts like
?2L? documented?
Thanks, Bryan

Line feed for a long character string
...one know how to make a line feed automatically based on the width of
console window? For example, when you cat() a long character string just
like this:
cat("Seminar series is an opportunity for students to learn about ongoing
researches in the field of mathematics, computer science, physics,
chemistry, and some other related programs. Students must complete a seminar
attendance form and return to their mentors.\n")
In my computer, about half of the string is displayed with a symbol ?$?at

rda variance partioning in vegan problems
...d had a similar experience.
My question is related to partitioning the variance in rda (vegan) results
for multiple groups of variables. I have a high dimensional dataset with
79 explanatory variables and 9 response variables. Within those 79
explanatory variables there are ~8 groups (e.g. water chemistry, land cover,
geography, surficial geology, etc). To partition out their unique and
binary interactive variance, I run the ~30 conditioned RDAs necessary to
determine the "pure effects" of each group and the "pure binary
interactions" of those groups with each other.
My method...

expressions and paste
I have written a function to plot data which will be used for various different chemistries.
A simplified version is:
plot_data <- function(risk,levels,chem,sd2,measure){
plot(risk, levels,main=paste ("per", sd2, measure, "\n in usual", chem))
}
The problem is with the title.
This works fine if the variable "chem" is just text, but if it is an expression then

ORC JIT api, object files and stackmaps
...ed register arguments.
I've figured out how to get access to the stackmaps for code that I load
into my system from dynamic libraries that our compiler generates.
The answers to questions above will help me get access to the stackmaps
from ORC JITted code.

Is there anyway to clip the bottom of a barplot?
Hi, all,
I need to show only values in a barplot from say 4-12. When I do
this, values below 4 are not cutoff. I would appreciate any input
into how I could cut the bottom part of the bar off.
