Best, Daniel ------------------------- cuncta stricte discussurus ------------------------- -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von R_Learner Gesendet: Wednesday, July 09, 2008 11:28 AM An: r-help@r-project.org Betreff: [R] Find the closest value in a list or matrix I have a long list of numbers [3.4,5.4,3.67,....], and I basically want to find the index of the number closest to this number that I have, let's say 5.43. How would I do this without writing a for loop (I have to do this many times for several lists)? Is there a "lookup" function in R?
