[R] Generate quasi-random positive numbers

Hello all: Is it possible to generate quasi-random positive numbers, given a standard deviation and mean? I need all positive values to have the same probability of selection (uniform distribution). Something like: runif(10, min = 0, max = 100) This way I'm generating random positive numbers

[R] filling list of data frames

Hello: I have a list of data frames, built like this: the second df is a result of a function applied to the first, and so on. So the ith df is always dependent on the (i-1)th df. I've been doing this using for loops. However I think I have too many for loops which is making my code run

[R] C++ and R

Hello: I have some C++ code and I want to know if it is ok to load it into R using .Call. Also, what's the difference between using Rdefines.h or Rinternals.h headers? It is just in the used macros? I've been reading Writing R Extensions but I'm a bit confused. Thanks,
