search for: cleverly

I have a situation where this is fine: > if (length(x)>15) { clever <- rr.ATM(x, maxtrim=7) } else { clever <- rr.ATM(x) } > clever $ATM [1] 1848.929 $sigma [1] 1.613415 $trim [1] 0 $lo [1] 1845.714 $hi [1] 1852.143 But this variant, using ifelse(), breaks: > clever <- ifelse(length(x)>15, rr.ATM(x, maxtrim=7), rr.ATM(x))

Hmm. Chuck: I don't see how this example represents incomplete/incommensurate recycling. Doesn't TRUE replicate from length-1 to length-3 in this case (mat[c(TRUE,FALSE),2] would be an example of incomplete recycling)? William: clever, but maybe too clever unless you really need the speed? (The clever way is 8 times faster in the following case ...) x <- rep(1,1e6)

I know that if: x = seq(1,10) d = c(7,3,2) and if I say y = x[d] then I get the vector y as (7,3,2). Very clever! This idea is used intensively with the boot library. Now consider the following code (which works): --------------------------------------------------------------------------- library(boot) sdratio <- function(D, d) { return(sd(D$x[d])/sd(D$y[d])) } x =

OS X R 4.3.1 Colleagues I often create multipage PDFs [pdf()] in which the text "Page X" appears in the margin. These PDFs are created automatically using a massive R script. One of my clients requested that I change this to: Page X of XX where XX is the total number of pages. I don't know the number of expected pages so I can't think of any clever way to do this. I

I didn''t see anyone post a link to David''s Interview by Lenz here on the list so I decided to post it. The interview can be accessed here: http://dev.mysql.com/tech-resources/interviews/david-heinemeier-hansson-rails.html I was very happy to see the interview on PlanetMySQL as just the other day I was talking about RubyOnRails on my MySQL blog which is syndicated

If I use an image in 6 places, I have to change it in 6 places. HOWEVER Suppose I cleverly used the footnote form of links. I.e: [Image alt text][LABEL] Suppose that markdown was clever enough to reference an external file (in .markdownrc of course) for the resolution of LABEL. NOW when I re-arrange the universe, I only have to change the reference in this one file, NOT in every fil...

I just spent a couple of hours trying to track down a maddening tricky problem. Here''s the backstory... I''m developing in OSX using locomotive and rails 1.1.2 My application suddently started behaving very inconsistently. I would go to a controller and the first time I went there, everything would work fine. If I refreshed, or hit another action, I would start getting

I want to be able to dial a 'pager' extension from an phone on my asterisk server, and have it ring all other extensions *except* the extension from which I am calling (because call waiting is enabled on most extensions by default) - effectively giving me the ability to page all other extensions from any phone. The solutions I've come up with so far (individual contexts for each

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I remember someone wrote a great document concerning Polycom server provisioning that provided a way to ensure that updates to the firmware did not overwrite customizations. I'll be damned if I can remember where I saw it. It may have been discussed during a VUC session or may have been on this list. Either way, I'm unable to google my way

Using Asterisk 1.6.1.9, I'm looking for a way to "share an extension" between a SIP phone (Cisco 7940) and a SLT on a FXS port of a Cisco 1760 (via sip) -- at any given time I want to be able to pick up either phone and it should be "bridged" to the other - just like having two SLTs on the same copper pair. The goal is to have a cheap cordless telephone sit right next

Just installed Aim for win 98 using Wine, and it ended up putting a nice Aim icon on my KDE desktop with the wine command in to start aim - i.e. wine "/mnt/win98/Pro...." This is getting really smooth! Simon

I'm sure you've seen this before: You need to slightly tweak the default installation of a major daemon - let's say you're running a big MySQL database and you need to put it on a different filesystem, mounted (for example) as /db So you move /var/lib/mysql to /db/mysql (and preserve all the file attributes, including SELinux), change /etc/my.cnf accordingly, start mysqld -

Hi, Would like to make an image however the values in z are not on an uniform grid. Have a dataset with length(x) == length(y) == length(z) x[1],y[1] gives the position of z[1] and would like to encode value of z by a color. looking for something like plot(x,y, col = z) where col for z is cleverly chosen from a colorscale. Hope I made clear what I am looking for. Thanks Eryk

Hi all, I have been using princomp() recently, its very useful indeed, but I have a question about how to specify the rows of data you want it to choose. I have a set of variables relating to bird characteristics and I have been using princomp to produce PC scores from these. However since I have multiple duplicate entries per individual (each bird had a varying number of chicks), I only want

folks, is there a clever way to compute the sum of the product of two vectors such that the common indices are not multiplied together? i.e. if i have vectors X, Y, how can i compute Sum (X[i] * Y[j]) i != j where i != j also, what if i wanted Sum (X[i] * Y[j] * R[i, j]) i != j where R is a matrix? thanks, murali

What I want to do is wrap all the scaffolded administrated pages for my webapp into an admin folder in the controllers and views folders. So... /app /controllers /admin issue_controller.rb article_controller.rb topic_controller.rb ... etc. ... /views /admin /issue _form.rhtml edit.rhtml list.rhtml new.rhtml

Is there some clever way of pasting results from R into Excel or Word, as tab limited format so they are easy to turn into a formatted table. Or is there some other way of doing this to avoid the time spent reformatting the output for presentation. If different, I am also interested in an answer to the same question but using S-Plus. Many thanks, Graham

Hello Wise Ones... I need a clever way around a problem with findInterval. Consider: vec1 <- 1:10 vec2 <- seq(1, 10, by = 0.1) x1 <- c(2:3) a1 <- findInterval(x1, vec1); a1 # example 1 a2 <- findInterval(x1, vec2); a2 # example 2 In the problem I'm working on, vec* may be either integer or numeric, like vec1 and vec2. I need to remove one or more sections of this vector;
