similar to: fwrite() not found in data.table package

You are asking about (a) a contributed package (b) for a package version that is not in CRAN and (c) an R version that is outdated, which stretches the definition of "on topic" here. Since that function does not appear to have been removed from that package (I am not installing a development version to test if it is broken for your benefit), I will throw out a guess that if you update R

I have setup a Solaris server to test packages before submitting to CRAN, in order to catch problems that might not reveal themselves on Fedora, Debian, OSX or Windows. The machine runs a Solaris 11.2 vm with Solaris Studio 12.3. I was able to compile current r-devel using the suggested environment variables from "R Installation and Administration" and: ./configure

Hi all, Probably a rudimentary question. I have a flat file that looks like this (the real one has ~10e6 elements): 10110100101001011101011 and I want to pull that into R as a vector, but with each digit being it's own element. There are no separators between the digits. How can I accomplish this? Thanks in advance! Matt -- Matthew C Keller Asst. Professor of Psychology University of

Hi all, I've had one of my most miserable R weeks in memory. I'm trying to deal with huge datasets (>1GB each) but am running up against those pesky memory limits. The libraries filehash and g.data are not very suitable for what I need. I haven't gotten into the sql thing yet. Most recently I've been trying to install the new package ff (not yet on the CRAN repository). I

Hi all, Is there a way to skip non-sequential lines using the "skip" argument in the scan function? E.g., I have a matrix with 100 rows and 1e7 columns. I open a connection and want to read only lines 5, 7, 9, etc [i.e., seq(5,99,2)] It might seem that the syntax to do this would be something like this (if only the "skip" allowed vectors in the same way colClasses does in

Hi all, Perhaps this is more of a unix question, but I'll give it a try here. I am running 9 different R processes at the same time (called from a shell script using R CMD BATCH). When I use the top program to monitor how they are doing, it is impossible to tell which R process is related to which R script. Is there a way to rename a specific instantiation of an R process in top with

Hi Matt Your method is the easiest way for me to install the 64-bit R. I followed the directions on your web site and then did the following: R --arch=x86_64 source("http://bioconductor.org/biocLite.R") biocLite(type = "source",lib = "/Library/Frameworks/R.framework/Versions/2.8/Resources/RLib64") I got many errors and warnings which I copied to the attached file.

hi all, I'm full of questions today :). Thanks in advance for your help! Here's the problem: x <- c('18x.6','12x.9','302x.3') I want to get a vector that is c('18x','12x','302x') This is easily done using this code: unlist(lapply(strsplit(x,".",fixed=TRUE),function(x) x[1])) So far so good. The problem is that x is a vector

Hi all, My graduate student is logging onto my macpro and running R through ESS aquamacs (with Mx ssh and then Mx ess-remote). Everything is working fine until we get to graphing. We are trying to give him the ability to look at graphics interactively. The ESS manual is not too helpful: "If you run X11 (See Section 13.3.2 [X11], page 68, X-windows) on both the local and remote machines

Hello all, I hate to add to the daily queries regarding R's handling of large datsets ;), but... I read in an online powerpoint about the ff package something about the "length of an ff object" needing to be smaller than .Machine$integer.max. Does anyone know if this means that the # of elements in an ff object must be < .Machine$integer.max [i.e., that ff provides no help with

Hi all, I have a vector, most of which is missing. The data is always increasing, but may do so in jumps. I would like to interpolate the NAs with 'best guesses', using something like filter(), which doesn't work due to the NAs. Here is an example: > x <- c(2,3,NA,NA,NA,3.2,3.5,NA,NA,6,NA) > x [1] 2.0 3.0 NA NA NA 3.2 3.5 NA NA 6.0 NA I would like a function that

Hi all, I'm giving a talk in a few days to a group of psychology faculty and grad students re the R statistical language. Most people in my dept. use SAS or SPSS. It occurred to me that it would be nice to have a few concrete examples of things that are fairly straightforward to do in R but that are difficult or impossible to do in SAS or SPSS. However, it has been so long since I have used

Hello all, I have some genetic datasets (gzipped) that contain 6 columns and upwards of 10s of billions of rows. The largest dataset is about 16 GB on file, gzipped (!). I need to sort them according to columns 1, 2, and 3. The setkey() function in the data.table package does this quickly, but of course we're limited by R not being able to index vectors with > 2^31 elements, and bringing

Hi all, SETUP: I have pairwise data on 22 chromosomes. Data matrix X for a given chromosome looks like this: 1 13 58 1.12 6 142 56 1.11 18 307 64 3.13 22 320 58 0.72 Where column 1 is person ID 1, column 2 is person ID 2, column 3 can be ignored, and column 4 is how much chromosomal sharing those two individuals have in some small portion of the chromosome. There are 9000 individual people, and

Hi Does Syslinux support fwrite for fat filesystem?Is it supported for other filesystem?As far as I understand the function exist but isn't fully implemented.Is that correct? I also found this thread that says about the samehttp://www.syslinux.org/archives/2011-August/017093.html Thanks,Tal

Hi, While testing a rails application on DreamHost (mod_rails), I found a really weird problem. If I submit form data which includes "fwrite();" (with semi-colon but without quotes), I get 503 error (Server temporarily unavailable). I checked out rails log file and it didn''t even reach the rails app. I assume the error was from web server. You may test this at

Hello, I've searched for an answer to no avail. I am wondering if anyone knows how to constrain certain correlations to be equal. I have family data with 2 twins per family plus up to 2 siblings. I would like to somehow constrain all the sibling correlations (twin-sib and sib-sib) to be the same while allowing the twin-twin correlation to be different. Here is some simulated code:
