...n R, so that I can preserve the SAS labels? If I have to change the SAS variable names to be 8 characters or less, to create a SAS version 6 transport file, I could probably do without the SAS labels as I have already read in the data into R from a CSV file.

...use. I have SAS Enterprise Miner as well and can get a scoring equation for the neural network (I don't have SVM), but the scoring code that SAS EM generates sucks and I would much rather extract a scoring equation from R. I am using nnet() for the neural network.

Hi mates, I have a problem. I am new to R and want to conduct the Fama/French asset pricing test. As I am from Germany, I cannot use the already computed factors from French's website, but need to compute them myself. So I have to sort a number of stocks into different portfolios using one factor, then subdivide these portfolios into several more using another factor, then compute portfolio

Hello, it wanted to know how I can extract of a dates frame the values peaks according to an interval that I establish. For example if dates are: 1 23 2 4 3 56 4 7 5 99 6 33 extract the date i wanted to divide into intervals of 2 an d to take alone the numbers 23, 56 and 99 of those 3 intervals. Thanks Ruben

I tried with: AM<-merge(A,B,all=TRUE) A1<-AM[is.na(AM$book),] to keep the rows with a NA value in the book column. The problem is...

...that some of the SAS procs, like HPMIXED, let you specify only one AR term for panel data so I am hoping there is some R package that will let me replicate what I can do in Eviews, and possibly even go beyond what Eviews can do by specifying both AR and MA terms.

Hi, I use nnet for my classification problem and have a problem concerning the calculation of the final value for my validation data.(nnet only calculates the final value for the training data). I made my own final value formula (for the training data I get the same value as nnet): # prob-matrix pmatrix <- cat*fittedValues tmp <- rowSums(pmatrix) # -log likelihood
