Hello, I have a concrete statistical question: I have a sample of an univariate mixture of an unknown number (k) of normal distributions, each time with an unknown mean `m_i' and a standard deviation `k * m_i', where k is known factor constant for all the normal distributions. (The `i' is a subscript.) Is there a function in R that can estimate the number of normal distributions k

Hello, I'm looking for a way to plot different data series on one graph. I have a series of hourly rainfall and quarterly flow measurements (i.e. 4 times an hour) of a catchment. The rainfall should be plotted in bars, the flow as a line. Both on the same X axe (time) but with different Y axes. The problem is the plot() function does not support add=TRUE... Furthermore I'm not sure

A few weeks ago, I upgraded Samba 3.0.1x to 3.0.14a . After the upgrade, all completed printjobs on all 40 printers stayed in samba's print queue (they were removed from the unix-printqueue). When I installed 3.0.20rc2, everything back to normal. But since the upgrade this weekend to 3.0.20, the same thing happens again: no jobs were removed from the samba printerqueue's. Removing

Dear R-users, In the function constrOptim there is an option to get an approximation to the hessian of the surrogate function R at MLE by declaring hessian=TRUE in the calls to the function optim. I would like to ask if it is advisable to get an approximate hessian for the funcrion f as follows: f''(theta)=R''(theta|theta_k)-B''(theta) where

Hi, I would be *VERY* interested in a reversed pwget (see http://www.martnet.com/~johnny/exploits/microsoft/NT/WinNT.passwordhashes.deobfuscation.html) to be able to automaticaly set first-time NT passwords ('smbpasswd -r' will only work if you first enter the 'previous' password) on our PDC (evt. remote from UNIX through some tcp (ssh?) connection). Bjart Kvarme seems to have

Greetings everyone, I have the following problem (illustrating R-code at bottom of mail): Given a training sample with binary outcomes (-1/+1), I train a linear Support Vector Machine to separate them. Afterwards, I compute the weight vector w in the usual way, and obtain the fitted values as w'x + b > 0 ==> yfitted = 1, otherwise -1. However, upon verifying with the

Jerry, I'm very sorry for this late answer. I should tweak my mailfilters (I didn't expect an answer anymore so I didn't check my samba-mailfolder) That's our situation: - I tried to revert to 3.0.20rc2 and got the error again - I installed 3.0.20 again and rebooted, and the problem went away! (I'm sure that all smbd, nmbd and winbindd daemons were killed before the

To Whom It May Concern: I have an R package and want to put this package be part of R-project and available to anyone who is interested in. The R package is created for my paper, titled "Acceptance Sampling Plans from Truncated Life Tests Based on the Birnbaum-Saunders Distribution for Percentiles". The paper has been accepted by Communications in Statistics: Simulation and

While developing updates to optimization tools for R (I was behind 3 of the 5 codes in optim(), but Brian Ripley did the implementation), I've been seeing this kind of error when the objective function cannot be computed so returns NA. Examples: attempts to divide by 0 or sqrt(-ve) or log(0). A crude work-around is to detect bad situations when evaluating the function and return a very

Hi, I'm trying to use R to cluster words with related meanings. Does anyone know of a non-hierarchical clustering method in R that produces non-exclusive clusters? With non-exclusive, I mean that words should be allowed to be part of multiple clusters. So my data matrix would look something like: T1 T2 T3 CLOWN_N 0 1 0 BANK_N 3 0 2 RIVER_N 0 0 2 FLOW_V 0 0 3 MONEY_N 2 0 0 PAY_V 2 0 0 The

Dear R users I have the following problem when calling optim() to minimize a function "f.obj" (= outer loop) that calls another function "f.con" (a contraction mapping, = inner loop). It seems to me that it is a numerical problem that I currently fail to take into account when coding. Calling optim(), for the first few iterations of the outer loop, everything seems fine; the
