Dear list, I'd like to use multiple imputations to try and save a somewhat badly mangled dataset (lousy data collection, worse than lousy monitoring, you know that drill... especially when I am consulted for the first time about one year *after* data collection). My dataset has 231 observations of 53 variables, of which only a very few has no missing data. Most variables have 5-10% of

Hi all, I have this (non-working) script: dataTest <- data.frame(col1=c(1,2,3)) new.data <- c(1,2) name <- "test" n.row <- dim(dataTest)[1] length(new.data) <- n.row names(new.data) <- name cbind(dataTest, name=new.data) print(dataTest) and would like to bind the new column 'new.data' to 'dataTest' by using the value of the variable 'name' as

I expected, that I will get the same prediction, if I multiply the weights for all classes with a constant factor, but I got different results. Please look for the following code. > library(e1071) > data(Glass, package = "mlbench") > index <- 1:nrow(Glass) > testindex <- sample(index, trunc(length(index)/5)) > testset <- Glass[testindex, ] > trainset <-

Hi, I am trying to use svm for regression data. this is how my data looks like: >dataTrain x y z 1 4 6 2 5 4 3 7 5 >classTrain a 2 3 4 >dataTest x y z 1 7 2 2 8 3 >classTest a 3 4 5 building the model model<-svm(dataTrain,classTrain,type="nu-regression") pred <- predict(model, dataTest) > pred 1 2 3.008842 3.120078 I

R-help, Sorry for posting again the same question (dated 26-03-2007) but all my mails have been sent to the recycle bin without possibility of recovering and thus I don't know if anyone has answer my query. Here is the original message: I'm applying a gam model (package mgcv) to predict relative abundances of a fish species. The covariates are year, month, vessel and statistical

Can someone please tell me what is up with na.action in aggregate? My (somewhat) reproducible example: (I say somewhat because some lines wouldn't run in a separate session, more below) set.seed(100) dat=data.frame( x1=sample(c(NA,'m','f'), 100, replace=TRUE), x2=sample(c(NA, 1:10), 100, replace=TRUE), x3=sample(c(NA,letters[1:5]), 100, replace=TRUE),

Hi all, I have exactly the same problem as the OP and tried the solution below, but I still get the error: 'Username IUCNNL\PC050$ is invalid on this system'.

Thomas, As F Harrel in a preceding message told me that you are the maintainer of Hmisc package, I write directly to you, with copy to the Rhelp list in case someone encountered the same problem and find some benefit in the response. I used quite often the function sas.get in Hmisc library which I is very, very useful. But, as trying to reuse it today it seems not to function anymore. I tried

Hi Vincent, have you found a solution that makes "force directory mode = 2770" able to apply to new created folders ? I have a similar problem: if I set by hand (eg. chmod 2770) the folder A and then I try to create an X element into that folder through samba I get the result needed ( group of X become overriden from parent folder A ) but the problem is that the new element X not

Dear All: Urgent help is needed. I have a data set in matrix format of three columns: X, Y and index of four groups (1,2,3,4). What I need to do is the following; 1- How I can subtract the sample mean of each group indexed 1,2,3,4 from the corresponding data values of this group and create new columns say X-sample mean and Y-sample mean? I tried to use the "tapply" but

Dear R users, I fitted a repeated measure model without random effects by using lme. I will use the estimates from that model as an initial estimates to do multiple imputation for missing values of the response variable in the model. I am trying to extract the within group correlation matrix or covariance matrix. here is my code: f = lme(y ~x0+x1+trt+tim+x1:tim +tim:trt,random=~-1|subj,
