Hello, Is there somebody who can demonstrate how to code a while loop that ends when a convergence between the values of two or more variables (say vectors) is reached? Thank you Regards [[alternative HTML version deleted]] __ R-help@r-pr

Re: [R] Query on while loop

I don't know how to say this charitably, but your post indicates that you **really need to go through an R tutorial or two.** Rather than give you answers to these very basic matters, a couple of hints: 1. A and P are vectors with 3 elements, not matrices . 2. I presume things like c11 and c32 a

Re: [R] Query - Merging and conditional replacement of values in a data frame

Your "assignments" (<-) are not legitimate R code that can be cut and pasted. Learn to use dput() to provide examples that we can use. You fail to say whether the time column of df2 is a proper subset of df1 or may contain times not in df1. I shall assume the latter. You also did not say whether t
