search for: iteractions

Hello, I am trying to use a for loop to name objects in each iteraction. As in the following example (which doesn't work quite well) my_list<-c("A","B","C","D","E","F") for(i in c(1:length(my_list))){ url<- "http://finance.yahoo.com" doc = htmlTreeParse(url, useInternalNodes = T) tab_nodes = xpathApply(doc,

I''m doing a fotolog for a company. It''s expected to manage about 100k of connections per day and about 1500 concurrents connections. What hardware should I buy to manage those numbers of connections? I''m planning to use slackware + lighttpd + fastcgi, but perhaps we will have to reuse some scripts in php, in that case I would use slackware + apache + mod_php + fastcgi

Dear all, I would like to create a graphics menu. There is a function "menu" which presents the user with a menu of choices labelled from 1 to the number of choices(in the package base). But it's an "iteractive" function. Actually, i work with GRASS and R (under linux) and i use the command R --vanilla<"name" to execute my routine. That why, i

...y if we did a little re-factoring. I wanted to keep it simple for now & not change any of the upstream QEMU code. This attached patch is against the current upstream QEMU CVS code, not Xen''s ioemu, since I wanted to work against pristine QEMU codebase & avoid any potential wierd iteractions with HVM stuff added to ioemu. The diff is $ diffstat ~/xen-qemu-pvfb-machine.patch Makefile.target | 3 b/hw/xen.c | 113 +++++++ b/hw/xenfb.c | 822 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ b/hw/xenfb.h | 35 ++ vl.c | 1 vl.h | 3...

...nction uses others C and Fortran functions and it works fine when I call it from a main() in a C program. But when I call it from R with .Call("name_of_the_c_function"), R gives me some weird output. This weird output is a worng answer to my optimization problem (sometimes after thousands iteractions, what does not occur when called from C) or a segmentation fault error. The kind of output depends on the machine I am using. At home I got a segmentation faul, in university I got those wrong values. I tried a memcheck in C and Fortran binaries, but everything seems allright except by 2 missing fr...

Hello. A few weeks ago, I need to calculate the Internal Rate of Return for irregular intervals. There is the package 'financial', with the function 'cashflow', calculating irr for regular intervals. So I developed xirr, managing irregular intervals, that's accepting a vector of dates as xirr Excel function. You can find the code at

Thanks for tracking this down. Yeah, I should use suppressWarnings(), you are right. Although, readLines() might throw another warning, e.g. for incomplete last lines, and you don't necessarily want to suppress that. TBH I am not sure why that warning is given: ? con <- file(tempfile()) ? open(con) Error in open.connection(con) : cannot open the connection In addition: Warning message: In

Dear all, I'm attempting to use a piecewise regression to model the trajectory of reproductive traits with age in a longitudinal data set using a mixed model framework. The aim is to find three slopes and two points- the slope from low performance in early age to a point of high performance in middle age, the slope (may be 0) of the plateau from the start of high performance to the

This has nothing to do with on.exit. It is an iteraction between where the warning is signaled in 'file' and your _exiting_ warning handler. This combination has the same issue, tryCatch(file(tempfile(), "r"), warning = identity) showConnections(all = TRUE) as does options(warn=2) file(tempfile(), "r") showConnections(all = TRUE) I haven't looked at the

Hi All Has anyone used Asterisk for a Call Center operation? What I mean is: given a list of phone numbers, can Asterisk dial each number, play a message and accept some DTMF? I ask because I am an employee of a non-profit company based in San Diego, CA. I already evaluated Voicent and Voxeo. The former has expensive licensing terms and the latter is not best suited for a call center. I would

Yeah, that's often a possible workaround, but since this connection was opened by readLines() internally, I don't necessarily know which one it is. E.g. I might open multiple

Hi, I am running a model with count data and one categorical predictor (simple model for me to understand it fully), I did in R a glm like this: glm(Recruitment~Depth, family=poisson). I get the coefficientes and confidence intervals and all is ok. But then I want to do the same model with Bayesian stats, here is my code: model { for (i in 1:232) { Recruitment[i]~dpois(lambda[i])

Hi, I''m a newbie in both Ruby and Ruby on Rails. I finished the Ruby on Rail Tutorial on Todo list and it was great. But, now I''m trying to understand the logic behind it, that is something that is not obvious on how each one of them ties together. Is there a flowchart that shows how the inner working of Ruby on Rails? In another words, let''s suppose we consider the
