similar to: Rbbg for 2.15.2

I am having a puzzling problem with bloomberg connection. When i  run from R prompt some code that has .... library(Rbbg) conn <- blpConnect(throw.ticker.errors = FALSE) print("connected") ... I establish connection every time and then proceed to get data when i run this code from R prompt. However, when i run this from a batch script, i get the following error output from Rbbg:

Hi, Is there a way to send an ESC command to the console from within a script window, without using the mouse ? Thanks, Tolga

Hi, Suppose I have an arbitrary function: arbfun<-function(x) {...} Is there a robust implementation of a numerical derivative routine in R which I can use to take it's derivative ? Something a bit more than simple division by delta of the difference of evaluating the function at x and x+delta... Perhaps there is a way to do this using D or deriv but I could not figure it out.

Hi there, Is there an implementation of the Gaveh Stehfest algorithm in R somewhere ? Or some other inversion ? Thanks, Tolga

Dear R Users, Does anyone know of a package which can generate random realisations of a double-exponential jump diffusion process with a drift ? Something where I can specify the likelihoods of an up or a down jump, the drift rate, and the mean size, and get back a vector of realisation of the process (for purposes of a Monte-Carlo). Kind regards, Tolga

Hi there, I have a function which has a variable called show as an input: richardson.grad <- function(func, x, d=0.01, eps=1e-4, r=6, show=F){ # do some things if(show) { cat("\n","first order approximations", "\n") print(a.mtr, 12) } #do more things and return } The show variable is being used as a flag to show intermediate

Is there a package in R which implements numerically solves pde ? Thanks, Tolga

Hi, Having a weird problem with the integrate function. I have a function which calculates a loss density: I'd like to integrate it to get the distribution. The loss density function is: lossdensity<-function(p,Beta,R=0.4){ # the second derivative of the PDF # p is the default probability of the pool at which we are evaluating the lossdensity # Beta is the correlation with the market

Dear R Users, I am working in an environment in which I am not able to compile any code. Sad, but true. Is there a Windows 32-bit version of 2-15.2 anywhere ? I am currently unable to use packages Matrix and mgcv because they appear to have been compiled for 2-15.2 but only 2-15.1 is available for download from the regular CRAN websites.

Dear Fellow R Users, I am having a problem with the Matrix package, in Windows XP on R 2.15.1 . This is the only package where I experience this. I remove the package first, re install, and then when trying to load, get a LoadLibrary failure as below. Thanks in advance for any assistance.

Hi, Am sure this is a trivial question but for some reason, haven't been able to figure it out. I want to bucket data in a vector, and then iterate over the buckets. Say the data set is: > cleandata[,4] [1] 26 26 26 26 26 26 26 26 26 26 26 26 61 61 61 61 61 61 61 61 61 61 61 89 89 89 89 89 89 89 180 180 180 180 362 544 544 544 [39] 544 544 544 544 544 544

Hi, I am trying to plot multiple lines on a graph. The function is particularly simple: sigma<-function(lambda) atm-2*rr*(lambda-0.5)+16*str*(lambda-0.5)^2 which uses the variables atm, rr and str... I define these as such: atm<-0.4 rr<-0.2 str<-0.1 and this plots fine: plot(seq(0.01,0.99,0.01),sigma(seq(0.01,0.99,0.01)),ylim=c(0,1)) Now, I want to plot the same function for

Dear R Users, I am trying to get plot.zoo to place monthy tickmarks/labels for a time series which spans daily data going back a bit over a year. Right now, I am getting only one tick mark on the x-axis for the beginning of 2008. How can I force plot.zoo to place more regular x-axis tick marks on a monthly basis ?

Dear R-Users, I am looking for a way to get legends placed automagically in an empty spot on a graph. Additional complication comes through my useage of multiple graphs on the same plot through mfrow. Is there a way to achieve this in R ? I have legends for each of the sub-plots.

Dear R Users, I am attempting to place a title to a graph with multiple plots that should go across the top of all the graphs, and not just one of them. I am using mfrow in par to plot. Can anyone suggest if and how this could be done ? Thanks in advance, Tolga

Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000. How can I display the tick marks for both on the left hand side without superimposing them, i.e. one set of tick marks in black right

Dear R Users, I am on Windows XP SP2 platform, using R version 2.7.2 . I was wondering if there is a way to find out, within R, the number of CPU's on my machine ? I would use this information to set the number of nodes in a cluster, depending on the machine. Sys.info() and .Platform do not carry this information.
