Re: [R] by function does not separate output from function with, mulliple parts

Dear John, Printing inside the function is problematic. Your function itself does NOT print the labels. Just as a clarification: F = factor(rep(1:2, 2)) by(data.frame(V = 1:4, F = F), F, function(x) { print(x); return(NULL); } ) #   V F # 1 1 1 # 3 3 1 #   V F # 2 2 2 # 4 4 2 # F: 1 <- this i

Colleagues, I have written an R function (see fully annotated code below), with which I want to process a dataframe within levels of the variable StepType. My program works, it processes the data within levels of StepType, but the usual headers that separate the output by levels of StepType are
