Hi, I am trying to change a SAS macro to R. here is my code. I get an error at the last line. attach(fram) dset1<-cbind(AGE,BMI,DEATH) > BMIGRP<-cut(BMI,breaks=3,right=TRUE) > AGEGRP<-floor(AGE/10)-2 > dset<-cbind(AGEGRP,BMIGRP,DEATH) > maxage<-max(dset[,1]) > minage<-min(dset[,1]) > #maxcls<-dset[,2] > #mincls<-dset[,2] >

Hello, I have question regarding the lrm function and estimating the odds ratio between different levels of a factored variable. The following code example illustrates the problem I am having. I have a data set with an outcome variable (0,1) and an input variable (A,B,C). I would like to estimate the effect of C vs B, but when I perform the summary I only get A vs B and A vs C, even though I

Hi, i do have a dataframe representing data from a repeated experiment. PID is a subject identifier, Time are timepoints in an experiment which was repeated twice. For each subject and all three timepoints there are 2 sets of four values. df <- data.frame(PID = c(rep("A", 12), rep("B", 12), rep("C", 12)), Time = rep(c(0, 0, 0, 0, 30, 30, 30,

Hi, I am trying to runn a age-period-cohort model, but here is what I am having problem with, hope you can help me! This is what I am trying to do: sumzero_a<-((A-min(A))/5+1) - mean((A-min(A))/5+1) where A is my age variable (numeric, the mid-point of a five-year age group), but I got the following error: Error in min(..., na.rm = na.rm) : invalid 'mode' of argument I am pretty

I'm working with 3 different data sets and applying this non-linear regression formula to each of them. nls(Y ~ (upper)/(1+10^(X-LOGEC50)), data=std_no_outliers, start=list(upper=max(std_no_outliers$Y),LOGEC50=-8.5)) Previously, all of the regressions were calculated in Prism, but I'd like to be able to automate the calculation process in a script, which is why I'm trying to move to

[Environment: Win XP, R 2.10.1] I'm trying to install the packages JGR and iWidgets required by the extracat package to make the interactive plots in the package work. I've tried various things, but nothing seems to work. Here is my most recent attempt, followed by my sessionInfo(). Does anyone have any suggestions how to make this work? > > library(extracat) Loading

Hello All, I just signed up to this list, so I apologize if this question has been asked before. I am trying to load an hdf5 file into R and running into some problems. Here are the steps I took to configure my environment: * R 2.10.0 (x64) on Mac OS X 10.6 * hdf5 1.8.3 installed via macports * hdf5_1.6.9.tar.gz from CRAN I suspect the problem I am having relates to

I'm using rpart to fit a tree using a large dataset: 7000 observations, 4651 variables. All but one of the variables (age) are binary. When I run the code: fit1 <- rpart(lowergi ~ ., data=dset,method="class") I get the error: Error in dimnames(X) <-list(dn[1L]], unlist(collabs, use.names=FALSE)) : Length of `dimnames' [2] not equal to array extent I have no idea

I am working on minimization of sum of squared errors for a problem that has 2 box-constrained parameters. I got the solution for this problem using "L-BFGS-B" method in optim function using an R code as res<-optim(par=c(parInit), fn=myFunction, method = c("L-BFGS-B"), lower = parMin, upper = parMax,

Hello everyone I have recently reported problems reading a certain directory from an NT server on this list (and speculated in causes). I have a few workarounds and now I'm looking for some feedback on what the proper fix is and for people to test if my patch works for them. Please test smbfs with and without the patch on the directory in this zipfile (all files are empty):

Hi, I have a data set look like this: ================================= Fruit Quty apple 20 banana 10 orange 17 apple 30 apple 15 orange 26 banana 15 .........and so on .......... ================================= The level of fruit is 30, that is, there are 30 different fruits. I'd like to compute some simple statistics for each different fruit and get output like this:

I'm attempting to calculate a regression in R that I normally use Prism for, because the formula isn't pretty by any means. Prism presents the formula (which is in the Prism equation library as Heterologous competition with depletion, if anyone is curious) in these segments: KdCPM = KdnM*SpAct*Vol*1000 R=NS+1 S=(1+10^(X-LogKi))*KdCPM+Hot a=-1*R b=R*S+NS*Hot+BMax c = -1*Hot*(S*MS+BMax) Y

Implementing the backend (or editing the current PPC backend as needed) is a definite option. This seems to be the real question... which is easier... maintaining the PPC backend or maintaining the rewriter. Currently (in admittedly trivial tests) I have gotten the rewriter to work and output C code. There are some outstanding issues to do with linking and accessing the reflection information

By linux derivative I meant that it borrows the linux GCC ABI... and it does. You can compile with an off the shelf GCC cross compiler and link the resultant object files ones compiled with the PS3 provided version. We have done it. Also, as both an XBox 360 and PS3 developer, there seems to me to be nothing in the TCRs/TRCs that preclude us from using a different compiler. There are rules

hello. I'm a student that work on R.(version 1.7.0) I need to some data frames such as "possum","Beams"'"kiwishade","dolphins",... . I typed help.search("possum") and so on,but the response was "No help files found with alias or title matching 'possum' using fuzzy matching.". I dont know what is "fuzzy matching"
