## Help: find the index of the minimum of entries

 Dear All, I would like to ask a question on how to find the index of the minimum of entries of a numeric vector, without using loops or user defined functions. Suppose we have a vector: a <- c(3,1,2) then, min(a) = 1 and its index is 2. Target:  how to get the index of this minimum? How to get the indices  if multiple entries assume this same minimum? Thank you, Chee         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
