Hi, I'm working on leaf characteristics of trees. Each tree is characterised by about 10 leaf traits. The trees were sampled at 9 different locations (about 20 to 30 trees/location, NOT balanced), grouped in 3 different climatic zones (Sahelian, Soudanian and Guinean) (NOT balanced). Further, each tree is characterised by some degree of human pressure (mutilation degree),...

Nope, the two proposed patches should resolve the underlying issue just fine as well as the self-host problem. Just writing to characterise the problem, which is slightly different to the OP's description. Alp. -- http://www.nuanti.com the browser experts

I hope a very basic R/S programming question is appropriate for this list... I have a function which returns a list of several (named) numeric values characterising an event history for a person. I want to invoke the function many (1000) times and create a vector of these lists to represent the histories of a population. At first, I thought that a data frame would be the appropriate way to

Is there a guide anywhere to embedding LLVM into a program to compile and run a DSEL? Thanks, Sean

...using earlier versions of R (Linux). A dataframe is created and new columns added to it by doing calculations using apply with various functions on some of the original columns. It's somewhat too involved to give a toy example that's reproducible. However, the resulting phenemonon can be characterised by the following: Browse[1]> dim(mod.df) [1] 409 5 Browse[1]> object.size(mod.df) [1] 31520 Browse[1]> is.array(mod.df) [1] FALSE Browse[1]> mod.df[1:5,] Error in as.data.frame.default(x[[i]], optional = TRUE) : can't coerce array into a data.frame The whole dataframe would d...

...ion: Suppose that the system is nonlinear such that the response to the sequence 0,2 is not the same as the response to 2, 0 -- it is not just a change of the response by the same amount. Or nonlinear in other weird ways (I don't just mean simple things like y~x^2). I am thinking that a way to characterise this might be to pretend that x is not a continuous variable and to represent it with 5 indicator variables. And then interactions between them would tell me about nonlinear effects? e.g. lm(y~ d1 + d2 + d3 + d4 + d5 + d1*d2) etc Does this make any sense? If so, please suggest a good way to go abou...

Hi All, Thanks for all your discussions which I read offline and enhance my knowledge. I just want to know how to make yield curve by bootstrapping using R. Please give me some subject-matter links and code links. Especially the Spot Yield Curve and YTM Curve.

Hi all, i have a CentoOS based Xen Dom0 running gitco xen3.3.1. I''m experiencing problems with debian Lenny FV domU. After some days of perfect working the VM start to consume all cpu and than i can only connect via ssh to VM and nothing work, neither the "top" command! Any idea? Thanks a lot and regards, Francesco

...eb site. The intent here is that the external journal be an NVRAM device (or a disk) which can be used to accelerate full-data journalling. Simulation using a normal RAM drive indicates that we can double throughput with some loads (dbench) but not others (synctest). More work is needed to fully characterise this. For the synchronous operations I've put together an application which attempts to simulate an MTA's behaviour. The simulator is called `synctest' and it is in ext3 CVS. There's a copy at http://www.uow.edu.au/~andrewm/synctest.c - I'd really appreciate it if the MTA gu...

...t? Mitigate what? Even by your account, this won't get them anywhere, unless it's so fast and heavy, it's DoS'ing your system. Other than that, they're just bloating your logs, nothing more. If you want to pre-empt this via firewall, you'll need to get extremely lucky to characterise these IPs (a sample of 2 is not enough) in such a way as to able to formulate a firewall rule. Mostly likely, this is a rented botnet. If you somehow figure out an oracular rule to discern bot from some user road-warrior *before* they connect, give me a call.

Hi, I need to build a simple, command-line method to generate a legal and "perfect" RTP stream across a network link, and analyse it on the other side and measure network performance. Want to do this for a number of links and over long periods. I'm trying to characterise performance of various available Internet links locally as input into a design project. Asterisk isn't ideal for me because I just want a one-way stream and in the case of things like Echo, Milliwatt, MusicOnHold etc the generated RTP stream is "synchronised" to the incoming RTP and...

Our research has led to the characterisation of a class of short RNAs transcribed from polycomb target genes that interact with polycomb repressive complex-2 (Kanhere et al., Mol Cell

I am looking at MM-estimates for some interlab comparison work. The usual situation in this particular context is a modest number of results from very expensive methods with abnormally well-characterised performance, so for once we have good "variance" estimates (which can differ substantially for good reason) from most labs. But there remains room for human error or unexpected chemistry which still causes some outliers. MM-estimates from robust regression with variance weights is a sugg...

...ompilers assume about it, to detect errors without too many false positives. We had quite a few survey responses saying something like "sanitisers have to allow XYZ, despite the ISO standard, because code really does it"; in a sense, what we're doing is trying to clearly and precisely characterise all those cases. If you or others can help with that, please do! But such tools are, useful and impressive though they are, aren't really testing code against all the behaviour ISO permits - as I understand it, they are essentially checking properties of single (instrumented) executions, whi...
