One-to-one matching?
Hi folks, Can anyone suggest an efficient way to do "matching without replacement", or "one-to-one matching"? pmatch() doesn't quite provide what I need... For example, lookupTable <- c("a","b","c","d","e","f") matchSample <- c("a","a","b","d") ##Normal match() behaviour: match(matchSample,lookupTable) [1] 1 1 2 4 My problem here is that both "a"s in matchSampl...

[LLVMdev] TableGen lookup table recipe?
Is it possible to define lookup tables as a list in tablegen, to map one value to another? Here's the template I was working on: ========================================= class LookupTable { list<int> mapping = [0, 8, 16, 24, 32]; } def LUT : LookupTable; class MyRegister<name, index> : Register<name> { let HWEncoding = LUT.mapping[index]; int otherVal = index; // required as well, ie. 'unmapped' } foreach reg 0-32 in { def R#reg : MyRegister&...

how to have 'match' ignore no-matches
Hi all, I think this is a very basic question, but I'm new to this so please bear with me. I'm using match to translate elements of a data frame using a lookup table. If the content of a particular cell is not found in the lookup table, the function returns NA. I'm wondering how I can just ignore those cells, and return the original contents if no match is found in the lookup table.

handling multiple lookup tables in rails
...ls/views/controllers for all these lookup tables are identical. I would think there would be a way to have 1 Controller (e.g. LookupController) 1 set of views (in directory /lookups) and a model for each lookup table. Then the Lookup controller would (possibly with a before_filter) figure out which lookuptable I want to edit (possibly with a route such as (lookup/:model) where :model would be the name of the lookup table I want to edit. Can anyone point me to either some documentation or provide hints on how to do this sort of thing cleanly? Below is the code I''m playing around with.......

best choice of user database file to work with postfix?
I'm setting up a Postfix and Dovecot combination. What I want to do is have a user database that (1) is not running from some engine (so not LDAP or SQL or such) ... and (2) is completely disassociated from system users (e.g. most email users are not in /etc/passwd and most /etc/passwd users are not email users). Ideal would be a one-file solution, which can be managed by text editing or
