I want to eliminate certain observations in a large dataframe (21000x100). I have written code which does this using a binary vector (0=delete obs, 1=keep), but it uses for loops, and so it's slow and in the extreme it causes R to hang for indefinite time periods. I'm looking for one of two things: 1. A document which discusses how to avoid for loops and situations in which it's

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 would like to use anonymous cvs, but it appears not to be working (again?). There was a discussion back in Jan-Feb about whether to continue supporting it, but it seemed that Tony Rossini got it working and the discussion left off there. Did someone decide to disable it, or is it just not working properly? Here's the details: $ cvs -d

I'm not sure if this is what you want. But the function coordinates() in sp package gives you the coordinates of SpatialObjects. Regards.

Hi all, I have a very good query related to printer sharing using samba. Following is the scenario... I had installed HP laserjet 9040Dn printer on redhat Enterprise linux 5. Shared it using samba. Used winbind protocol to integrate linux with windows AD 2003. Now i am able to see printer in Active directory as well as linux computer account in AD. But unable to set option lpadmin -p printer

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

Do the mapped unix groups need to be added to the new host before attempting the upgrade? There is nothing in the docs regarding that. Am I mistaken in thinking that the AD does not rely on matching or mapped unix groups

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

Hi all, For computational reasons, I need to estimate an 18x18 polychoric correlation matrix two variables at a time (rather than trying to estimate them all simultaneously using ML). The resulting polychoric correlation matrix I am getting is non-positive definite, which is problematic because I'm using this matrix later on as if it were a legitimately estimated correlation matrix (in order

Hi, I want to retrieve a function from a source line-number, is this something possible to achieve? I tried the following code snippet with LLVM-7 but it doesn't seem to workhttp://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend <http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend:> Is there specific documentation I can refer to implement this?

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, 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

Dear R users, I ran into this curious problem: > d <- rnorm(100) > d.density <- density(d) > sum( d.density$x * d.density$y) [1] 2.517502 Admittedly the method of computing the mass under the density curve at line 3 is crude. But 2.5 is pretty far from 1, the value it should be. I tried a few other dataset and got similar result. Am I missing something obvious? Or is the return

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

A new package `survey' for analysing complex survey samples is on CRAN. It handles stratification, clustering, and unequal sampling probabilities in descriptive statistics, glms, and general maximum likelihood fitting. The package is still under development: - it doesn't do the finite population correction to variances - it needs some real life worked examples Most importantly,
