This script below pulls yahoo data via a function in quantmod, then massages the data around to forumalate a 3D graph with RGL library, attached is a ggplot to show the data i'm trying to create a surface with in separate line geoms . the issue is that the 3D graph looks very ugly and cut up because of the limited quantities of points on the front month expirations.. can anyone tell me whats

Hi, I was wondering if someone could please help me. I am doing a logistic regression to compare size at maturity between 3 seasons. My model is: fit <- glm(Mature ~ Season * Size - 1, family = binomial, data=dat) where Mature is a binary response, 0 for immature, 1 for mature. There are 3 Seasons. The Season * Size interaction is significant. I would like to compare the size at 50%

...I am testing for effects of ornamentation on foraging behavior of wolf spiders. I tested spiders at two different ages (penultimate vs. mature) and of two different phenotypes (one species tested lacks ornamentation throughout life [non-ornamented males] while the other acquires ornamentation upon maturation [i.e. brush-legged males]). I tested a sample of brush-legged and non-ornamented males (as both penultimates and matures) in 2009, and an additional sample of brush-legged males in 2010 (as both penultimates and matures again) because I had a very small sample of brush-legged males in 2009. I woul...

Hi, I am contemplating migrating from maildir to dbox. However, I wonder about the maturity of the dbox code, as it appears to not be widely used. Does anybody have some success stories? My primary driver is to have non-changing file names, and thus smaller backup deltas. Are there other advantages that I should pursue? I read in the wiki that the migration is straightforward, but I did not

Dear R helpers   I am calculating the 'Yield to Maturity' for the Bond with following characteristics.   Its a $1000 face value, 3 year bond with 10% annual coupon and is priced at 101. The yield to maturity can be calculated after solving the equation -   1010 = [100 / (1+ytm)]  + [100 / (1+ytm)^2] + [ 1100 / (1 + ytm)^3]   This can be solved by trial and error method s.t. ytm = 9.601%.

Hi, I got the following problem. I am doing a maximum likelihood estimation for a Kalman Filter. For this purpose, I have to invert an error matrix Ffast of dimension "no. parameters X no.parameters". The usualy optim methods often find only local minima, so I decided to make the optimization using the SANN algorithm, which is very slow already. However, this becomes a real problem

Hello, I am a system manager of a datacenter. Is this moment, we about 30-40 xen servers running 2 or 3 domUs each of them. We are now using (standalone) xen over debian lenny. We manage each xen server independently, but we are looking for a central management console. At this moment, I have the doubt about using citrix xenserver (the free edition) or XCP. I didn''t know much

Hello, I have data on the maturity of two morphs of fish. I want to test whether their maturity is evolving differently or not on a temporal scale (month). The maturity variable (independent variable) is continuous and the morph and month variables (dependant variables) are categorical. Because the data show variance heterogeneity, I modeled it with the function gls: kg1 =

Hello, it would be nice to know in the community as it is the maturity of the fourth samba at putting in a production environment. It would be wise to put the Samba 4 in a production environment, or would play the most recommended solution samba + openldap?

Hello, we are writing rich internet user interfaces and like to call R for some of the computational needs on the data, as well as some creation of image files. Our objects communicate via the SOAP interface. We have been researching the various packages to expose R as a SOAP service. No current CRAN SOAP packages however. Found 3 to date: RSOAP (http://sourceforge.net/projects/rsoap/)

  Dear R helpers,   Suppose I am reading a csv file as   yd    =   read.csv("mydata.csv")   The actual data in the mydata.csv file is say for example like this -     Date             day_1     days_15     day_30    days_60    days_90      days_180 Nov 11            5             14               1               3              21               8 Nov 10            7             

Hello everybody, I am not very advanced in my R skills so I really hope anybody of you can help me with this problem on which I have been working for hours. I would like to write a function, which can guess the yield-to-maturity for any values: C, NV, r, s1, s2, and for a freely chosen tolerance (tol). Additionaly, for freely chosen T; -> s1, s2, s3, ..., sT I appreciate your help so much.

We have a Teliax IAX trunk that we use as an overflow for our four regular business lines into our local Asterisk PBX (Trixbox). We have our Teliax account set up so that it goes to a Teliax voicemail box if it cannot reach our Asterisk server, and we have the channel set up for 5 simultaneous connections. Occasionally, calls are sent to the Teliax voicemail box for no apparent reason. In

Hi there, I have a piece of Matlab code I use to optimise a trding strategy. If there are any Matlab/R specialists out there, I would appreciate your help in doing the exact same optimisation in R. I suspect I would use nlm() in R but am not sure where to define my constraints. I have attached my Matlab code below for reference. Many thanks. Constraints function [c,ceq]=TriskellConstraints(X)

That may be, but in view of the fact that you can even get a version of CDE that works (very well) on Centos 7 (https://github.com/dcantrell/cderpm if you're interested), I find it

Right, I understand that. I was hoping there was such an implementation using ANTLR since it looks like a fairly mature project. I'm not sure how stable or mature Elsa is (but comments to clarify that would be appreciated.). E.g., a quick scan of their Web page shows the comment that they only have a partial type checker. It also says their template instantiation is incomplete.
