Hi R-users,   I have this code here: library(numDeriv)   fprime <- function(z) { alp  <- 2.0165;   rho  <- 0.868;   # simplified expressions   a      <- alp-0.5   c1     <- sqrt(pi)/(gamma(alp)*(1-rho)^alp)   c2     <- sqrt(rho)/(1-rho)   t1     <- exp(-z/(1-rho))   t2     <- (z/(2*c2))^a   bes1   <- besselI(z*c2,a)   t1bes1 <- t1*bes1   c1*t1bes1*t2 }   ## Newton

I would like to solve a nonlinear eqn using newton method and here is the code:   library(numDeriv)   fprime <- function(z) { alp  <- 2.0165;   rho  <- 0.868;   # simplified expressions   a      <- alp-0.5   c1     <- sqrt(pi)/(gamma(alp)*(1-rho)^alp)   c2     <- sqrt(rho)/(1-rho)   t1     <- exp(-z/(1-rho))   t2     <- (z/(2*c2))^a    bes1   <- besselI(z*c2,a)  

Hi r-users,   I would like to solve for z values using newton iteration method.  I 'm not sure which part of the code is wrong since I'm not very good at programming but would like to learn.  There seem to be some output but what I expected is a vector of z values.  Thank you so much for any help given.   newton.inputsingle <- function(pars,n) {  runi    <- runif(974, min=0, max=1)

Hi, I have a TrixBox install with a Sangoma A200 and 4 FXO ports, there are 3 BT lines connected directly to these ports. One of the lines has BT FeatureLine Compact and this is the line I am having problems with, the other 2 lines are working perfectly, detecting CID, answering incoming calls and placing external calls via SIP devices. I am receiving a error log entry: chan_zap.c:

We recently upgraded from Dovecot 1.2.4 to 1.2.6 (with the sieve patches of course). Everything has been running quite well since the upgrade. The occasional issue with assert-crashing when expunging has gone away. However, one of our users seems to have triggered a new issue. She's been the only one to see it, but whenever she logs in, her imap process segfaults immediately. It appears that

Dear All, It's been several times I observed a very strange behaviour with R 1.2.0 under Windows NT 4.0 (with sp5): accuracies are lost in many cases. Things are back to normal when I exit R and restart it. Here is an example of my last encounter with this: > bt1 <- c(7.3, 8.1, 8.4, 7, 6, 7.2, 6.7, 8.3, 9, 7.4, 8.6, 6.2, 6.9, 7.6, 5.3, 5.6) > bt1 [1] 7 8 8 7 6 7 6 8 9 7 8 6 6 7 5 5

I am having difficulty installing the package "lattice". First I tried downloading it from the CRAN site (in the normal way) : the message said it worked but when I typed library I got an error message ("there is no package"). Second I tried installing it from the local zip. I have reproduced the result below. utils:::menuInstallLocal() package 'lattice'

Dear all, Does anyone know if the PLM package (to run Panel Data Analysis) accepts quarterly data? The package vignette and documentation only use annual data -and the only time index available seems to work for years.

Does anyone know how to read SPSS .por (ie Portable) files? The foreign package only deals with SPSS .sav files and not with those with a "por" extension.

Does anyone know how to retrieve the residuals after running an ERS unit root test on a time series (urca package)? There are no 'residuals' or 'res' (or similar) slots in the ur.ers-class, but a plot instruction - ie plot(ur.ers(....)) renders amongst other things a residual plot. If an augmented Dickey-Fuller test is run, an object of ur.df-class is generated which contains a

I am using the function prop.test (base package), which returns a list with class "htest". All I want to do is to assign one of its values to a variable, but I do not want R to print the results and added warning message whenever I invoke the function. How can I prevent R from printing on using prop.test? Regards, Jos? Luis Mr Jos? Luis Iparraguirre Senior Research Economist Economic

I could not find a package to run panel data unit root tests in R (there's a STATA module, though - PANELUNIT- and routines for Sarno and Taylor's MADF test, Levin-Lin-Chu's test, Im-Pesaran-Shin's Test, etc, to do this). Hence, I am toying with the idea of having a go at writing up one for R, but would like to know whether anyone is already working on this. José Mr

R-helpers I have 120 small Excel sheets to read and I am using library(xlsReadWrite): one example below. I had hoped to read sheets by looping over a list of numbers in their name (eg Book1.xls, Book2.xls, etc). I thought I had seen examples which used eval-parse-paste in this way. However, I have not been able to get it to work.. 1. is this a feasible approach? 2. if not

Dear R users, Consider the first two columns of a data frame like this: > z[,1:2] x y 1 1 1 2 2 2 3 3 3 4 1 4 Imagine that y represents the times that the value x happens in a population. But z is not exactly a frequency table, because in z we have x=1 twice. So, the x=1 in the first line and the x=1 in the fourth are not the same, differing according to a third variable in

Hi, I have a Data Set x and I want to check with a Kolmogorow-Smirnow-Test, if x comes from a Subbotin Distribution, whose density function is: function(x,location,scale,tail) # Exponential power (=Subbotin) { const<- 2*scale*tail^(1/tail) *gamma(1+1/tail) z<- (x-location)/scale exp(-1/tail*abs(z)^tail)/const } How can i do this? Thank you --
