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 <- functio...

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)]...

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 parameters being passed to this function on invocation or the structure of the return value expected. I would very much appreciate it if somebody familiar with this package could provide an example illus...

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 > nHatv It is allowed and even desirable to make set S contain se...

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

...than IEEE 754. > > But I think it's suitable for the sorts of places we currently use > hard-floats. I guess you (and Philip) are saying there are dragons here? Numerical analysis is hard. Every numerics expert I have ever worked with considers trying to re-invent floating point a cardinal sin of numerical analysis. Just don’t do it. You will miss important considerations, and you will pay the price for it later. Plus, anyone in the future who wants to modify your code has to learn a new set of non-standard floating point numerics, and without a well-defined specification it’s n...

...st rates (R and Z)). I actually wrote a plotting function to represent all this, the result is attached -- please have a look at it and help me... I need advice in the following: I need two sets of colors for B and F which are easy to distinguish (when printed on a color laser printer), represent cardinality (ie have an intuitive mapping to an interval) or at least ordinality. I have experimented with the following: Bcolors <- hsv(.6, seq(0.2, 1, length=5), 1) Fcolors <- hsv(seq(.1,0, length=5), seq(0.2, 1, length=5) this is what you see in the plot. What colors would you use? Do you th...

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).

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 ar...

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 way I know to it is using the text() f...

...(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 2nd level heap etc.) while chunks of BitSets easily fit into the first processor cache. Moreover the Bit operations or, xor, and, andnot, cardinality, clone, flip, equals, intersects are much faster done for BitSets than equivalent functions written for logical arrays. Is there any equivalent for BitSet in R? The vector type "logical" seems to be not equally powerful and I do not know its memory requirements. In BitSets a Bit requ...

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 it was only...
