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...

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 al...

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?

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 the end that looks like this: > cat("Seminar series is an opportunity for students to learn ab...

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
