Dear R-helper, I am working with ROCR of Tobias Sing et. al. to compare the performances of logistic and nnet models on a binary response. I had the performance plots, but I have problem finding out other performance statistics (eg. MSE/ASE, AUC). Any help on this? Thanks Ilham [[alternative HTML version deleted]]

Dear list, I want to combine several plots in one graph. I did this: plot(a1); plot(a2, add=TRUE); ...plot(a5, add=TRUE) The problem is the more plot we put, the more complex the graph. Is there any way to label each line; or other way just to make sure I know which one which? Thank you for the help, Ilham [[alternative HTML version deleted]]

Hi, Ia m working in discretized data. Here my data: x <- c(2,1,3, 5), and I want to make (0,1) data based on the length of each component in x. So the new data should like: y = (0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1). I spent too much time with "seq", "rep". Still didn't get it. Any help? Thanks Ilham [[alternative HTML version deleted]]

Hi R help, I run my data in nnet with skip layer, factor response (with 0 & 1 values) and explicitly put softmax=T to compare the result of the default nnet with no softmax specification. I assume this should give me the same result. I got the result the default one, but not the softmax version and I got the error message that I did not quite understand. test6.nn.skipT.softm.Yfac <-

I am wondering how to run 'garch' function of 'tseries' package in R2.6.1. I installed R2.3.1 and R2.6.1 in my PC (Windows XP Home) and run a following simple GARCH function in both versions: >garch(dSP[1:300], order = c(1,1)) where 'dSP' is daily return series of a stock index. R2.6.1 can not finish calculation and also I can not stop the

Hi I have just upgraded from R2.6.0 to R2.7.1 (running on Windows) and a part of my code that previously ran ok now gives an error. The following is a simple example to demonstrate my problem. > a <- array(c(1,2,3,4,5,6,rep(NA,6)),dim=c(6,2)) > apply(a,2,sd,na.rm=T) In R2.6.0 this gives (which is what I would like) [1] 1.870829 NA In R2.7.1 it gives the following error

I am seeing a peculiar installation problem with the R installation files for Windows: R2.6.1 fails to install on MS-Vista with a file corruption issue. But, the same R2.6.1 exe does install OK on Windows ME. The same problem exists with R2.3.1: Fails to install on Windows Vista Succeeds install on Windows ME Succeeds install on Windows 2000 and Windows 98 so it cannot be the installation

Hi, I want to install Rgraphviz on a windows vista pc. The only source file that I found in the bioconductor homepage is a tar file. I can't install from this using the packages command in the R menu. I would like to get some tips on how I can do the installation. Can I just place the extracted Rgraph folder (from the source tar file) in the library folder of R2.6.1 along with the other

Dear R-Help, I have used R2.6.0 until I recently installed also R2.7.2 (see details below) In R 2.6.0, the following script using the function 'var' (cor(stats)): x.test <- c(NA, NA, NA, NA) var(x.test, na.rm=T) gives the output: NA In R2.7.2 the output of the same script generates an error message and stops R: 'Error in var(x.test, na.rm = T)

We are constructing growth charts (age/weight and age/length) for children with diagnosis that impacts weight/length. But we we don't know how to use R for producing growth charts. We are collection data of Age, Weight and Length. The data are used to produce diagnosis-specific Growth charts (like the CDC Growth Charts:

hi, is there a way of calculating of measuring dependence between two categorical variables. i tried using the chi square test to test for independence but i got error saying that the lengths of the two vectors don't match. Suppose X and Y are two factors. X has 5 levels and Y has 7 levels. This is what i tried doing >temp<-chisq.test(x,y) but got error "the lengths of the two

Dear R users, I have just moved to R2.6.1 under Opensuse linux 10.3. I used to work with R under XPpro. Is it "normal" to have a visual aspect of R under linux different ?

Dear All, I am trying to build a simple ggplot, but where the scale is reversed, i.e. the largest numbers are on the bottom. An example of the code I am using is > plotdata<-data.frame(x=1:10, y=runif(10)) > plot<-ggplot() > plot<-plot+layer(data=plotdata, mapping=aes_string(x='x',y='y'), geom='point', stat='identity', size=4) >

I was just looking at the daily checks and it seems the "r-release Windows x86_64 (32-bit)" column is running R2.6.0. Is that correct? Possibly related, an error is being flagged in that column for TSMySQL, which appears to be a problem that should be caught in the other columns too. It is something that has been fixed in my sources for awhile. (I think it was fixed in the
