I have a list of data frames like this: a<- data.frame(x=runif(10), y = runif(10), Acc = 1) b<- data.frame(x=runif(10), y = runif(10), Acc = 0) ls<- list(a,b) and I want to remove the data frames from ls that have Acc values other than 1. How do I do that? Thanks for any help! Matthew

...alog. BUT, the file dialog never appears. Furthermore, if I then type choose.files() into the R Console, about half the time the file dialog appears and about half the time it doesn't. Any help anyone can give me is much appreciated. I cannot see what I am doing wrong here. Thanks, Carl Finkbeiner

...data set has 16 subjects (2^16 permutations) and 500 samples, which leads to more than 32 million t-tests. I have a loop version of the program working, but it would take a few weeks to complete the job and I was hoping that someone could tell me how to do it faster? thank you kindly, Matthew Finkbeiner -------------------------------- "Sample" "C1" "C2" "PermN" 1 5 8 perm1 1 4 3 perm1 1 6 4 perm1 2 2 6 perm1 2 3 1 perm1 2 7 4 perm1 1 8 5 perm2 1 3 4 perm2 1 6 4 perm2 2 6 2 perm2 2 1 3 perm2 2 7 4 perm2 1 5 8 perm3 1 3 4 perm3 1 6 4 perm3 2 2 6 perm3 2 1 3...

Hi, A critical regression has been discovered in e2fsck. The problem was introduced in upstream 1.41.5 and is causing updates to block group descriptors to be lost after journal replay. Our 1.41.5.sun2 (.sun1 too) e2fsprogs version also suffers from this problem. We are working on rebasing our e2fsprogs package on 1.41.6 (see bug 19852). Until the new rpm is available (should be very soon), we

I am trying to interpolate missing values using spline and am running into some strange problems. first, this works just fine: x<- c(1:10, rep(NA, 3), 14:20) y<- c(rnorm(10), rep(NA,3), rnorm(7)) s<- spline(x,y, n=length(x)) plot(x,y) lines(s, col="blue") but look at what happens with my real data (sorry for the long vectors here): x<- c(-9.816, -9.801, -9.801, -9.795,

I don't have enough RAM for this problem, so I need a work around. This is what I want to do: y<- sample(2^32, 100000, replace=FALSE) but my machine won't let me do that. so I now do this: x<- seq(1,2^32, by=100) y<- sample(x, 100000, replace=FALSE) this works fine, but by selecting every 100th item, it introduces a systematicity that may be problematic. I've tried

I have a list of data frames like the following: set.seed(123) a<- data.frame(x=runif(10), y = runif(10), sample = seq(1,10)) b<- data.frame(x=runif(10), y = runif(10), sample = seq(1,10)) L<- list(a,b) All data frames in the list have the same dimensions. I need to calculate the sample means for x and y. The real data are lists of several thousand quite large dataframes, so I need

I'm sorry for what I'm sure is a terribly simple question. I have a large dataframe along these lines: S<- 1:3 d<- data.frame(cbind(S=rep(paste('S',S,sep=""),each=30), trial=rep(1:3,each=10), FactorA=rep(paste('L',1,sep=""),each=30), Acc= c(rep(1,each=20),rep(0,each=10)), Sample=rep(1:10,3), DV= sample(runif(10),10))) but where each
