This is not about the failure on some platforms, which is an important issue. However, what is below may provide a temporary workaround until the source of the problem is uncovered. FWIW, the problem seems fairly straightforward for most optimizers at my disposal in the R-forge (developmental) version of the optimx package at https://r-forge.r-project.org/projects/optimizer/ I used the code ## KKristensen19nlminb.R f <- function(x) sum( log(diff(x)^2+.01) + (x[1]-1)^2 ) opt <- nlminb(rep(0, 10), f, lower=-1, upper=3) xhat <- rep(1, 10) abs( opt$objective - f(xhat) ) <...

Hi, I'm not sure what the policy of this list is and I bet everyone has a spam filter, so nobody might have noticed, but we got spammed. Can anyone send mail to the list or do you have to subscribe first ? -- dag wieers, dag@wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power]

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters). I have an issue with auto-replies - it is vulnerable to spamming with forged email address. Forging can be prevented with several Postfix settings, which I did in the past - but was forced

I've noticed unstable behavior of nlminb on some Linux systems. The problem can be reproduced by compiling R-3.5.2 using gcc-8.2 and running the following snippet: f <- function(x) sum( log(diff(x)^2+.01) + (x[1]-1)^2 ) opt <- nlminb(rep(0, 10), f, lower=-1, upper=3) xhat <- rep(1, 10) abs( opt$objective - f(xhat) ) < 1e-4 ## Must be TRUE The example works perfectly when

...am to continue anyway. Please note that the use of KMP_DUPLICATE_LIB_OK is unsupported and using it may cause undefined behavior. For more information, please contact Intel(R) Premier Support. But KMP_DUPLICATE_LIB_OK=TRUE changes nothing. I had a look at: http://software.intel.com/en-us/articles/opm-abort-initializing-libguide40dll/ which suggests there may be a conflict between libguide40 and libiomp5md, but I can't find any loaded R packages that link against libiomp5md... Does anyone have any ideas? Many thanks, Ernest

Dear R-er, For a non-linear optimisation, I used optim() with BFGS method but it stopped regularly before to reach a true mimimum. It was not a problem with limit of iterations, just a local minimum. I was able sometimes to reach better minimum using several rounds of optim(). Then I moved to optimx() to do the different optim rounds automatically using "Nelder-Mead" and

...I realized that optimx() has just enough difference in syntax from optim() to be a nuisance and was heavy to maintain. Also I wanted parameter scaling to work for all methods, as in optim(). However, Ravi's efforts easily convinced me that trying multiple methods was a good idea, so there is an opm() function. We also had an option for polyalgorithms and at one point for multiple starts. I've put them in polyopt() and multistart() -- the combination in optimx was driving me nuts when doing any work on the code. Ravi, I hope this doesn't offend. The optimx ideas are still there, but th...

All, I would like to apply a set of rules to each row of the sample data set below. The rule sets are the guidelines for determining an individual's date for retirement eligibility. The rules are found in this document, http://www.opm.gov/feddata/RetirementPaperFinal_v4.pdf. I am only interested in the top two categories for retirement eligibility, the CSRS and FERS plans. The data set has four variables Date of Birth (DOB), service computation date (srvCompDT), retirement plan (retirePlan), and the age at which the employee e...

Running CentOS 4.2 with all updates. I've been using sendmail for my MTA since forever. I've grown used to it and I can make it do what I want it to. However (there's always a catch, isn't there)... Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to

Hi, Both vapply() and sapply() support the 'USE.NAMES' argument. According to the man page: USE.NAMES: logical; if ?TRUE? and if ?X? is character, use ?X? as ?names? for the result unless it had names already. But if 'X' has names already and 'USE.NAMES' is FALSE, it's not clear what will happen to the names. Are they going to propagate to the result

I am used to sendmail and am using Postfix now and am uncertain of some features. I typically would comment out the line in sendmail.mc that went something like 'accept unresolvable domains' I tried using smtpd_sender_restrictions = reject_unverified_sender reject_unverified_smtp and this seems a bit too restrictive and got some bounces on legitimate senders so I'm

Got a question hopefully someone can answer - I am working on functionality to match on certain nodes of a largish (65mb) xml file. I implemented this with REXML and was 2 minutes and counting before I killed the process. After this, I just opened the console and loaded the file into a string and did a regex search for my data -- the result was almost instantaneous. The question is, if I can get
