Hi, I'm using the library cluster to cluster a set of figures (method CLARA). Somebody that it work with clustering would know informs what I make to evaluate the clustering?

Hello, I'm applying an arithmetical function the color (R,G,B) of each pixel of a figure and it's very slow. This is common? Other thing, are there some library to make modification in figures, eg, to alter size? If not, somebody knows some software that makes this, or either, to resize figures automatically, therefore I go to need to apply to a bank. Tks, Francisco.

Hello, Someone use this package? I would like to know if this package has some method to classify images? Tks, Chico. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Francisco Júnior, Computer Science - UFPE-Brazil "One life has more value that the world whole" ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

people, I'm using the pixmap library and method read.pnm() for to read figures and it's giving the following error: Error in substr(inpstr, com1, stop = ns) : evaluation is nested too deeply: infinite recursion? I think that to be because of its size. Am I correct? Tks, Francisco. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Francisco Júnior, Computer Science - UFPE-Brazil "One

Hi, I don't obtain to use try to capture an error of read.pnm(). I was using: res <- try(read.pnm(file_name)) But I don't understand that the variable res represents, or eiher, as I can access its attrbites.

How I make the below matrix | a^0 0 0 ... 0 | | a^1 a^0 0 ... 0 | | a^2 a^1 a^0 ... 0 | | . | | . | | . | | a^n a^(n-1) a^(n-2) ... a^0 | with no loops, where "a" is a constant? ======================================================================== C?zar de Freitas Depto. de Estat?stica - UFPE Recife - Pernambuco - Brasil

Reposting from virt-tools mailing list: Hi! I'm facing a problem that could be triggered by some lacking of support from libvirt on Open vSwitch (or could be my mistake). I have interests in researching on virtual networks and SDN. To keep things simple, I've decided to use libvirt/virt-tools to manage VM's since my focus is on the network, instead of using a full feature system

Sorry about the odd terminology, but I suspect that my intent might be completely missed had I used "aggregate" or "classify" (each of which appears to have some rather special meanings in statistical analysis and modeling). I have some data about software builds; one of the characteristics of each is the name of the branch. A colleague has generated some fairly interesting

Dear List, I've been working with Asterisk CVS-v1-0-09 and i'm trying to enable attended transfer feature. but i just can't do it work. I've already set "atxfer = *" (and many other combinations) and all extensions on extensions.conf have the t and T option. But when I'm going to test, it doesn't work. Is there any other file that i have to configure in order to

If you want to use row names to take a row subset of a data.frame then there is a bug when - One row has a name which is a completion of another row name - The shorter name comes after the longer one - You want to retrieve the row with the shorter name An example: R> x <- matrix(1:4, 2, 2, dimnames=list(c("abc","ab"), c("cde","cd"))) R> x cde

I have just upgraded from Red Hat Linux 5.2 to version 6.0 (with GNOME) on an intel box. I have also upgraded to the latest R version (0.64.1-2 rpm) and have also installed the corresponding GNOME rpm. However, I am not able to start R: [cribari at edgeworth install]$ R /usr/lib/R/bin/R.binary: error in loading shared libraries: /usr/lib/R/bin/R.binary: undefined symbol: __setfpucw [cribari at

Changing the default now would require a long deprecation cycle to give everyone who uses `[.data.frame` and relies on partial matching (whether they know it or not) enough time to

Hi folks, Can anyone suggest an efficient way to do "matching without replacement", or "one-to-one matching"? pmatch() doesn't quite provide what I need... For example, lookupTable <- c("a","b","c","d","e","f") matchSample <- c("a","a","b","d") ##Normal match()

The pmatch help (see also section 4.3.2 in the R Language Definition) claims that pmatch with duplicates.ok=FALSE provides the same functionality as R's argument matching algorithm, modulo how empty strings are matched. Here's an undocumented inconsistency between pmatch and R's argument matching algorithm: > sessionInfo() R version 3.0.1 (2013-05-16) Platform:

Dear Ivan, thanks a lot, that is helpful. Still, I feel that default partial matching cripples the functionality of data.frame for larger tables.

Hi Hilmar and Ivan, I have used your code examples to write a blog post about this topic, which has figures that show the asymptotic time complexity of the various approaches, https://tdhock.github.io/blog/2023/df-partial-match/ The asymptotic complexity of partial matching appears to be quadratic O(N^2) whereas the other approaches are asymptotically faster: linear O(N) or log-linear O(N log N).

is there a howto or similar for configuring dovecot as a user to strip mime. ideally i would like all html copies deleted, but graphics, etc dumped to ~/public_html and replaced with a url. i have a super crappy link so html, etc usually jams my spool. i can usually wget things however hence this desired approach. bonz.

Hi, A noobie question: I'm simply trying to run a conditional statement that evaluates if a substring is found within a larger string. I find that if it IS found, my function returns TRUE (great!), but if not, the condition does not evaluate to FALSE. ex): if( grep("hi", "hop", fixed = TRUE) ) print('yes, your substring is in your string') else

Hello, an S4 class "Foo" is defined with a setter, $. For several reasons, the setter calls a function, .foo.update(). However, bypassing the argument names of the setter does not work. Question 1: Why not and how can I fix this? Question 2: What is the way to define either the function or the setter to modify the original object (not returning the modified copy of it an overwrite the
