similar to: "Out of memory" install error message

First a general comment on posting style, could you please be more specific about where the error occurs as without this it is very difficult to identify what the problem is. Now concerning your problem. When I tried the code I posted yesterday I thought it worked fine. I've tried it again now and found that the data.frame TAB3 actually only has one column and the names "A",

Hi Given that things like the following work > a <- c("-.1"," 2.7 ","B") > a [1] "-.1" " 2.7 " "B" > as.numeric(a) [1] -0.1 2.7 NA Warning message: NAs introduced by coercion > I naively expected that the following would behave differently. > b <- c('10%', '-20%', '30.0%',

Hi I've been greatly enjoying the functionality the zoo package offers. However I've hit a snag with the following code > a <- zoo(matrix(1:10,5,2), 2001:2005) > a 2001 1 6 2002 2 7 2003 3 8 2004 4 9 2005 5 10 > a[I(2003), 2] 2003 8 > a[I(2003), 2] <- NA Error: subscript out of bounds > I've also tried > coredata(a[I(2003), 2])

Dear R-List, I am very new to R and programming itself, so my question may be easy to answer for you. I tried a lot and read through the manuals, but I still have the following problem: I have 2 data-frames: Number<-as.numeric (Number) Name<-as.character (Name) TAB1<-data.frame (Name,Number) - it looks like this:- Name Number A 2 A 3 A 6 B 8 B 12 B 7 C 8 D 90 E 12 E 45 佲仸

Hi all I have a Model like this: class Member < ActiveRecord::Base attr_accessible :username, :email, :first_name, :last_name end I have created a scaffold using script/generate scaffold member members Using the URL localhost:3000/members/edit/1 I can edit all attributes, including created_at, lock_version etc.! But it should only show the attributes I listed in attr_accessible! What

I am accustomed to the LIBSVM package, which provides cross-validation on training with the -v option % svm-train -v 5 ... This does 5 fold cross validation while building the model and avoids over-fitting. But I don't see how to accomplish that in the e1071 package. (I learned that svm(... cross=5 ...) only _tests_ using cross-validation -- it doesn't affect the training.) Can

Hey all, I can't seem to get the princurve package to produce correct results, even in the simplest cases. For example, if you just generate a 1 period noiseless sine wave, and ask for the principal curve and plot, the returned curve is clearly wrong (doesn't follow the sine wave). Here's my code: library(princurve) x <- runif(1000,0,2*pi); x <- cbind(x/(2*pi), sin(x)) fit1

Hi, Recently, I installed the 1.1.0 version of R (for Windows), since it includes an implementation of Projection Pursuit (I failed to write my own version of PP as a standalone C++ program). As far as I know, R offers two interfaces/sintax for the ppr() function. The first one requieres a regression formula and a data frame. The other requieres X, a matrix with the explanatory variables, and Y,

Hello everyone: I keeps using rsync to backup my files on my laptop from one folder to another, and to reduce disk usage, so I use "--link-dest" option for incremental backup like this: *rsync -a --link-dest=/local/old /tmp/myfile /local/new* And "/local/old" is backuped some days ago, I use "--link-dest" option to keep unchanged files as links to new destination

Hello: I first use rsync on Cygwin in Windows, and make a fully old backup like this: rsync -a --force test 192.168.0.10::ttt/old/ Then in cygwin, I use "--link-dest" option to do a incremental backup: rsync -a --force --link-dest=../old/ 192.168.0.10::ttt/new/ * "new" directory contains updated files, and unchanged files are hard linked to "old" directory, rsync
