Hi, I want to get a clean succinct list of all levels for all my factor variables. I have a dataframe that's something like #1 below. This is just an example subset of my data and my actual dataset has 70 variables. I know how to narrow down my list of variables to just my factor variables by using #2 below (thanks to Bert Gunter). I can also get list of all levels for all my factor

Hello kind and R-knowledgeable souls! I am trying to use read.fortran to read in old datasets in 80-column-card format with no separators between variables (just 80 columns of solid digits). I comprehend the instructions for specifying the columns for each variable, but I can't understand how to assign the variable names after reading the help pages for read.fortran, read.fwf and

Hi, Jarkko: Thanks for the quick reply. I understand I can use ActiveRecord to specify the relation between the table as you have suggested, The part that I have trouble to understand is 1. Since I have a third table ProvWorkAtDept, do I need to specify this table somewhere when I define Provider or Dept? 2. If the provider view has both the provider name and several depts the provider

Hello, I tried to install the proprietary ATI radeon x700 graphics in Centos 4.3 with the capability of 1280x800.

Hi everyone, Colleagues of mine at Lawrence Livermore National Laboratory (LLNL), having seen the advantages of working closely with LLVM, have decided to toss their hat into the ring and would like to hire an LLVM-focused compiler engineer. I collaborate with LLNL regularly, and I'm excited that they're taking this step. I expect that a qualified applicant will find this position both

Dear Helpers   I have a sample frame and i have sampled from it using three methods and now i want to calculate the statistics but i only get the population parameters.   H <- matrix(rnorm(100, mean=50000, sd=5000)) sampleframe=data.frame(type=c(rep("H",100)),value=c(H)) sampleframe   str=strata(sampleframe,c("type"),size=c(20,), method="srswor")

Dear all, I have to select 122 stratified random samples from a population of >3900 cells. I have 41 strata and I have to draw a different number of samples from them(between 2 and 8). I have tried to apply the funtion strata following the instruction in the manual: strata(dataframe, stratanames=NULL, size, method=c("srswor"), pik,description=TRUE) but I get the error

Hello, I'm running R 2.10.1 on Windows Vista. I'm selecting a random sample of several hundred items out of a larger population of several thousand. I realize there is srswor() in package sampling for exactly this purpose, but as far as I can tell it uses the native PRNG which may or may not be random enough. Instead I used the random package which pulls random numbers from random.org,

Hallo, I'm trying to sample a matrix with simple random sampling without replacement but seem to have a problem with the matrix length. Both sample() and srswor() use length() which returns the number of columns in matrix. This means that to function it seems that the sample size exceeds the matrix length. I need to sample the whole matrix for there are auxiliary variables I need for further

Hello, We have written a program (below) to model the effect of a covariate on observed values of a response variable (using only 80% of the rows in our dataframe) and then use that model to calculate predicted values for the remaining 20% of the rows. Then, we compare the observed vs. predicted values using a linear model and inspect that model's coefficients and its R2 value. We wish

Hi everybody, I read about the development state ... samba as an ad domain controller and that many functions / group policies have been implemented. Still, there is some work in progress. Is there a documentation where I can look up the functions not implemented yet? Regards, Ulrich Schneider

rsync 2.5.0 still has a bug where it hangs under some circumstances. The hang is beyond my abilities to track down. I'll keep trying, though, but here are details in case they're of use to anyone else: - Code configured & built on Solaris 2.5.1. - Same binary run on Solaris 2.5.1 (client) and 2.8 (server). - Using rsh transport, but also fails with ssh - Does not fail with

I am following the directions found in the HOWTO and am running into trouble, maybe someone can shed some light on things for me and tell me what I'm doing wrong. I will print the commands I'm using to try and create the samba BDC and we'll go

On a side note, try recently released health report tool, and see if it does diagnose any issues in setup. Currently you may have to run it in all the three machines.
