Hi, My name is Katie and I was wondering if you could help me with my problem. I am trying to write a function in R that computes the statistics (mean, standard error, confidence intervals) for stratified samples. I am not that familiar with R and I am having dificulties setting this function up. Any help or tips on where/how to do this? Best, Katie [[alternative HTML version deleted]]
