Hello, How do I implement a cardinality constraint with constrOptim? I want to minimize (least square) a%*%x = 4 subject to x1<2 x2<1 x3<4 count(x1, x2, x3)= 2 (cardinality constraint) Is there a way to specify binary integer variables with constrOptim? Here's my code so far: a <-matrix(1:3,1,3) fr <- function(x) { (a%*%x-4)^2 }

This is not a nice name (format is generic; cardinal is not a class) for a nice function, which I would like in several places in R code and therefore would like to become part of R (under a better name !) format.cardinal <- function(i, sep="") paste(i, c("st","nd","rd","th")[pmin(4,i)], sep=sep) # Try format.cardinal(sample(1:20))

Function DEoptim in package DEoptim for differential evolution defines an optional parameter fnMap: fnMap "an optional function that will be run after each population is created, but before the population is passed to the objective function. This allows the user to impose integer/cardinality constriants." Unfortunately, there is no further documentation decribing the kind of

Is there any R package addressing problems of constrained optimization ? I have the following "apparently" simple problem: Given a set V with fixed cardinality: nv Given a set S whose cardinality is a parameter: nHat Let the cardinality of the intersection S.and.V be: nHatv The problem consists of maximizing nHatv/nv subject to a penalty if nHat >

Hi, I have noticed a strange behavior: after the added one of the options "window_match" in scale and switcher plugins; these do not show some windows like gmplayer or amsn's windows This is the output of xprop $ xprop _NET_WINDOW_DECOR(INTEGER) = 20061011, 46149375, 4, 4, 27, 4, 4, 4, 27, 4, 9, 0, 36965, -11, -34, -68, 0, 582, 32767, 0, 0, 32869, 571, -34, -68, 0, 32767,

I'm trying to write a program that reads an ogg stream and check all the CRC values along the way. But I have big trouble with computing the checksum, or at least I never got checksums that match the one that is in the ogg file. I do set the CRC field in the header to 0 before calculating it. I start with 0 and have no xor at the end. I feed page header with all lacing values and the page

Looking for some help from the UK please. I backed up all my Asterisk configuration before re-installing the server from 32 -> 64 bit. Unfortunately I did not transfer the backup to another machine!!!!! I now have a TDM400P that is not picking up the line. Can you see what I have done wrong when I have rebuilt the config please: dahdi_scan ---------- [1] active=yes alarms=OK

Hi, I am plotting a policy function (result from a dynamic stochastic optimization problem, discretized approximation). The policy function maps from an 2 x 2 x 2 x 3 x B x F state space to a B x F state space (B and F are usually between 4-6, and represent domestic and foreign savings. The other variables are income (Y), inflation (Pi), domestic and foreign interest rates (R and Z)). I

Hello all, To start with, these measurements are on Linux with R 2.9.2 (64-bit build) and Python 2.6 (also 64-bit). I've been investigating R for some log file analysis that I've been doing. I'm coming at this from the angle of a programmer whose primarily worked in Python. As I've been playing around with R, I've noticed that R seems to use a *lot* of memory, especially

I worte in my last mail that when I ue compiz git fullscreen videos are no longer ontop of the gnome-panel... that means that the gnome-panel is still visible while playing the video in fullscreen. The commit which I said may caused it has nothing to do with it compiz does not build if I revert it). again with older compiz and metacity it works fine. (now I am running 20070316). Anyone else wiith

Hello, I would like to know how to count the number (cardinality) of a specific element in a single row of a matrix. At this time I have 30X3 matrix. The first column is the treatment number for each data point. I would like to know how many of each treatments are in this matrix. i.e. I want to know how many 1's are in column 1, how many 2's are in column 1, etc. I found a couple

Dear useRs, I was asked to produce a survival curve like this: http://www.palug.net/Members/jabba/immaginetta.png/view with the cardinality of the riskset at the bottom. I do not like doing it, because it doesn't add any valuable information and because it doesn't discriminate between died and censored. Nevertheless, is there someone able to tell me how to do it? Currently the only

Hello, We have an otherwise working Samba PDC+LDAP setup but for one minor detail. The shadowLastChange is not updated when the user sets his password from a Windows workstation (all the necessary Samba*-fields as well as userPassword is updated in LDAP). We've enabled 'ldap passwd sync = Yes' in smb.conf. slapd.conf contains the appropriate access rule for the said field. The

...and German "ß". If you don''t speak any of the affected languages, imagine if the current method deleted all ocurrences of the letter "s" from English strings, and so generated paramater strings like: "234-aint-loui-cardinal" rather than "234-saint-louis-cardinals".

Hi all, I consider writing a R package on statistics for the sorting method as a hobby. I have written a private Java application that I could use as a basis. Therefore I'd like to ask two questions: 1) logical vectors: Bit storage (small) and capable of bit operations? The Java application relies on BitSet(s) for efficiency reasons. Arrays of logical values cost far too much memory (in the

I''m seeing some odd behavior around the should_receive() when given a block combined with some cardinality. For example, with the following... my_mock.should_receive(:foo).twice do |i| puts i end ... the spec passes but i never gets puts''ed. With the following... my_mock.should_receive(:foo) do |i| puts i end ... i gets puts''ed twice but the spec fails because
