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

Hi, I have a list p with different size dataframes and length of over 8000. I'm trying to calculate correlations between the rows of dataframes of this list and columns of another dataset (type data.frame also) so that first column is correlated with all the rows in the list dataframe. Some information from another dataset is also included to the final output (all.corrs). This worked a

[This message is not always serious, but it addresses a real problem.] A problem with R's present name is that it is not very well suited to search engines, although Google at least seems to cope as long as you have sufficient other terms to filter out Toys R Us. Initials remain a problem. I suppose "R" is just too culty to do away with, but perhaps we could come up with a longer

Dear R users, I have some problems with the parLapply function from the "parallel" package: I use parLapply on a pretty big R object without changing the object within the called function. If I execute parLapply alone, everything works fine. It seems that the object resides only once in the memory. But if I use the same call within another function, the object seems to be multiplied to

Hi, I'm using Xapian in Python2. I'm trying to replicate an analysis that somebody else performed in Lucene. To do that I need to do a search for a multi-word query in which particular fields are boosted - preferably at query time. That is, given a query like "the cat is lying on the mat" (with an OR operator, ignoring word positions but with stemming and stop words removed),

Hi, I am writing a term paper about linear regression and analysis of variance in R and SPSS. I am a bit confused because I get different estimates for the regression coefficients from R and SPSS. Does anyone have an explanation for this? As I am not so experienced in data analysis, I don't know why this happens. Thank you for helping, Katja

Hi all, I do have a mailbox-quota problem in dovecot 2.0.19 that is beond my understanding. Could someone pls. give me a hint. - user1 max. mailbox quota is set to 1GB, the current mailbox size of user1 is 15MB - user2 max. mailbox quota is set to 10MB, the current mailbox size of user1 is 10kB - user1 shares the folder 'shared_folder' to user2 with all rights (read, write ...) -

Hello Rhelpers, I need to run the following loop over a large number of data-sets, and was wondering if it could somehow be vectorized. It's more or less a cumulative sum, but slightly more complex. Here's the code, and an example dataset (called tab in my code) follows. Thanks in advance for any suggestions! res<-0 for (i in min(tab$Date):max(tab$Date)) { if

Dear help community, I'm a R-beginner and use it for my master thesis. I've got a mixed model and want to analyse it with lme. There are a lot Cofactors that coult be relevant. To extract the important ones I want to do the stepAIC, but always get an error warning. Structure of my data: data.frame': 72 obs. of 54 variables: $ Block : Factor w/ 3 levels

Hi, my data frame consist of 8 Variables and 120 000 observations. With those datas I am running a PCA and after I want to calculate the Volume of the PCA-cloud of certain subsets of my data. Does anyone have an idea about a function that can do this? Thanks [[alternative HTML version deleted]]

Hello, I'm trying to transform reaction times which are not normally distributed to an ex gaussian or an inverse gaussian distribution, but I don't really know how to use the exGAUS() function. Can someone show me a script in which data has been transformed? Thanks in advance k [[alternative HTML version deleted]]

I cannot find the equivalent of cex.axis for lattice. How does one change the size of the labels of the axis tick marks in xyplot et al.? Thanks in advance for any help. Pedro. p.s.: I looked in the FAQ and Trellis manual, but I diidn't find an answer... so I hope I am not asking about something obvious. I am using R 1.4.1 on windows 9X. Lattice 0.4-0 --

Hi, I cant log into my Fedora core 2 box from another linux machine or an OSX machine It worked the very first time I tried then never since. I have downl?oaded the newest openssh sources, and done ./configure make make install as root but seems to still use the old openssh.

We are running 4 Solaris10u7 DomUs on a b113 Dom0 I''d like to upgrade the Dom0 to b122 but not rebuild the DomUs. Below is a typical DomU xml dump. Is there anything obvious that will bite me in upgrading from 113 to 122? Thanks John virsh # dumpxml achilles2 <domain type=''xen'' id=''1''> <name>achilles2</name>

This is only partly a question about R, as I am not quite sure about the underlying statistical theory either. I have fitted a non-linear mixed-effects model with nlme. In the fixed part of the model I have a factor with three levels as explanatory variable. I would like to use Tukey HSD or a similar test to test for differences between these three levels. I have two grouping factors:

Dear all, I am pleased to announce the CRAN release of a new package called 'KFAS' - Kalman filter and smoother. The package KFAS contains functions of multivariate Kalman filter, smoother, simulation smoother and forecasting. It uses univariate approach algorithm (aka sequential processing), which is faster than normal method, and it also allows mean square prediction error matrix Ft to
