Problem with Rsync or Users will be Users?
I'm using CWRSync 2.6.9 protocol 29 on a Windows 2003 Standard R2 server. I'm trying to copy files onto a local usb harddrive. Both filesystems are NTFS. Rsync is failing to copy some files due to the file name length. I kind of assumed that Rsync could handle the same file name length that Windows users are allowed to enter. :-) Is there *anything* I can do with Rsync to allow these

Indexing in anova summary output of the form: summary(aov(y ~ x1, Error = (x1/x2)))
Hi, there I'm trying to get the value of the Mean Square from the ANOVA model summary that comes from specifying the error term, and am wondering if one can actually do this ( I know it's possible when using anova(lm) objects and the like, but I'm having a tough time with it under this framework). There does appear to be some indexing in the output of this type, but perhaps not

deSolve, extracting variable values from inside ode function
I'm just getting to grips with using ode function and have used the examples and vignettes to produce a small model of a one-pool, michaelis-menten, enzyme kinetic reaction. The rate of flux of substrate into pool A is constant (fluxoa) however the rate of flux out of pool A is controlled by the HMM equation (v = Vmax/ ( 1 + (Km / Concentration A )) ). This function works fine and

openssh for windows - bug ?
Good morning, I would like to send you a bug with openssh for windows - versions OpenSSH_3.7.1p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7b 10 Apr 2003 OpenSSH_3.8.1p1, OPENSSL 0.9.7.d 17 Mar 2004 When I try to execute a remote command via ssh from unix machine to windows machine with openssh installed, the return code of ssh is always 0 even if remote command fails.

is this an ANOVA ?
Hi all, I have a very easy questions (I hope). I had measure a property of plants, growing in three different substrates (A, B and C). The rest of the conditions remained constant. There was very high variation on the results. I want to do address, whether there is any difference in the response (my measurement) from substrate to substrate?

2x2 Contingency table with much sampling zeroes
Hi, I'm analyzing experimental results where two different events ("T1" and "T2") can occur or not during an experiment. I made my experiments with one factor ("Substrate") with two levels ("Sand" and "Clay"). I would like to know wether or not "Substrate" affects the occurrence probability of the two events. Moreover, for each

coxme() random effect syntax
Hello: I would like to run a Cox proportional hazards regression on crayfish dislodgement at different water velocities by crayfish size class and substrate (rock) type. Additionally, there is a covariate variable, rock movement that may be influencing crayfish dislodgment. So... I have crayfish size class (CFSZCL) and substrate type (SUBSZ) as fixed factors influencing the dislodgment of

Kernel panic kickstarting to CentOS 4
I have an older server I am trying to update to CentOS 4.3 but I can't get to the installer screen because the machine kernel panics when booted from the install CD.

slightly OT: (un)supervised clustering?
Hi, my question is not exactly about R... What I am looking for are hints and directions on suitable methods (available in R or elsewhere) to solve a grouping (or pattern recognition) problem of environmental features in an environmental gradient as described below. Given environmental sampling data set (Depth, Presence of sand, Presence of boulders, Presence of clay). 1 1 1 0 1 1 0 0 1 1

Tapply for Group Specific Means and Proportions
UseRs, I am working on a dataset (see small example below) where individuals were followed on a specific date-time combo and multiple repeated measurements were taken (e.g., height in meters, behavior class in 2 letter code). Observation numbers varied between individual (ranging from 1 observation for each date-time combo to >50) I am trying to summarize the data into 1 row per

two bugs in rsync 3.0.6 - ampersands in filenames, double quoting required
1) deleting path/to/(Something) Word Word Anotherword--Word Word.pdf IO error encountered -- skipping file deletion I think either the -- is causing it to fail, or more likely, the next filename, which it didn't bother to print out, which has an ampersand in the name, causes it to fail. I am using SSH as a substrate, of course, and I think you guys failed to escape things, so the ampersand

R2.4 xyplot + panel.number problem
Hi all; I'm trying to display a 2 panel plot for the Puromycin data from R with 2 different non-linear models fitted to each group. The problem is that as far as I know panel.number doesn't work in the latest version of R. Can anyone give a hint how to solve this? Here is the code that I used before and now doesn't work xyplot(rate ~conc| state,Puromycin,

formula substitution by its calculated value
Dear R_Users, I am confronted to a technical issue that I wouldn't even know how to start to handle and where to look at. It is about data manipulation in a dataframe and value substitution Imagine I have a matrix describing a set of chemical equations. Colnames are Components names and Rownames are Reaction names Each cell in that matrix corresponds to the stoechiometric coefficient to the

dropping factor levels in subset
Dear all, I've taken a subset of data from a data frame using crb<-subset(all.raw, creek %in% c("CR") & year %in% c(2000,2001) & substrate %in% ("b")) this works fine, except that all of the original factor levels are maintained. This results in NA's for these empty levels when I try to do summaries based on factors using by(). Is there a simple way to drop

Gathering "metal" stats
Hey All, I’m attempting to gather stats on usage of the “metal”, by which I mean the physical host’s hardware. I would like to know the CPU, IO, and network stats for the hardware. Normally I would get these from /proc/stat, /proc/diskstat, and ifconfig respectively. However, because of the segregation of VMs and Dom0’s special relationship as a paravirtualized I don’t know if I can trust this

?OT: Probabilistic Simulation
Sorry this may well be defined as Off Topic. I apologize in advance. I am interested in performing what I think would be a probabilistic sensitivity simulation. I've done some crude ones before in excel but I'm wondering if R can help me do it more effectively? I have a set of theoretical variables for simplicity lets use (what I think) is an easier example: I have a peg and a hole
