Hello all, I am conducting a randomization test on a given dataset. One of the covariates, gender, is randomly assigned 1000 times to create a randomization dataset (rand.data). To these 1000 datasets, I fit a full model (see below) and the aim is to generate a distribution of LRT statistic under the null. Here are some of the questions I have: 1. I am using for() loop to fit the dataset

Hi, I just wonder if R is still used for PK analysis. However, I have to use R for some purposes anyways. Here is a really strange problem I am running into and I hope to get some assistance from the group. The following code works fine in S-Plus (Population estimates and MAP estimates look reasonable ). cs.fit<-nlme ( CONC~phenoModel(CID,TIME, DOSE, lCl, lV), fixed = lCl+lV ~1,

Hello, I am a beginner in R programming and recently heard about this mailing list. Currently, I am trapped into a simple problem for which I just can't find a solution. I have a huge dataset (~81,000 observations) that has been analyzed and the final result is in the form of 0 and 1(one column). I need to write a code to process this column in a little complicated way. These 81,000
