search for: precedence

The documentation (help("Syntax")) gives the operator precedence of the assignment operators and help, from highest to lowest, as: ?<- <<-? assignment (right to left) ?=? assignment (right to left) ??? help (unary and binary) If I understand correctly this implies that `a = b ? c` and `a &lt...

Precedence is a property of the parser and has nothing to do with the semantics assigned to various symbols. Using just core R functions you can see the precedence of '?' is between those of '=' and '<-'. > # '=' has lower precedence than '?' > str(as.list(pa...

Dear all, `?Syntax` documents that `?` has the lowest precedence, right under `=`. Indeed it reads: *The following unary and binary operators are defined. They are listed in precedence groups, from highest to lowest. * and ends the list with *<- <<-* *assignment (right to left)* *=* *assignment (right to left)* *?* *help (unary and binary)* I belie...

...and 14955, which seems to have the explanation (but was marked as closed/fixed??). The parser does list '?' as lower precedence than '=', but '='-assignments are not normal 'expr's which can appear as arguments to '?'. (Presumably because of named arguments: f(a=b) differs from f(a<-b).) Other tokens which have lower precedence than assignments are flow-control items, IF ELSE WHILE FOR...

...imes-out and the IPv4 address of the server mounts successfully. Disabling IPv6 altogether works around the problem as expected, but is a bigger hammer than we wanted to use. :-) I found posts from others in a similar situation, and proposed solutions included modifying /etc/gai.conf to use: precedence ::ffff:0:0/96 100 I cp'd /usr/share/doc/glibc-common-2.12/gai.conf to /etc/ and tried that, with several other permutations (e.g. uncommenting other blocks of "label" and "precedence" settings) but none achieved the desired effect. Am I misunderstanding how this is suppos...

I am trying to set up a function which processes my data according to the following rules: 1. if (x[i]==0) NA 2. if (x[i]>0) log(x[i]/(number of consecutive zeros immediately preceding it +1)) The data this will apply to include a variety of whole numbers not limited to 1 & 0, a number of which may appear consecutively and not separated by zeros. Below is an example with a detailed

hello all, im trying to figure out the precedence of security parameters in smb.conf. i know that settings in specific shares take precedence over settings in global; 'invalid users' takes precidence over all other security settings. but others im not so clear on, such as: does 'read only' take precedence over 'write list'?...

Hello, I'm using pigeonhole-0.2.3, it works fine. I tried to verify some build in checks of vacation concerning precedence or auto-submitted header lines. It looks like sieve-test ignores header lines like Auto-Submitted: auto-submitted Precedence: bulk Return-Path: MAILER-DAEMON at ... if I have a vacation script like require ["vacation", "regex", "fileinto", "variable...

I agree there is no reason they _need_ to be the same precedence, but I think SPECIALS are already have the proper precedence for both unary and binary calls. Namely higher than all the binary operators (except for `:`), but lower than the other unary operators. Even if we gave unary specials their own precedence I think it would end up in the same place. `...

The unquoting discussion is IMHO separate from this proposal and as you noted probably better served by a native operator with different precedence. I think the main benefit to providing user defined prefix operators is it allows package authors to experiment with operator ideas and gauge community interest. The current situation means any novel unary semantics either need to co-opt existing unary operators or propose changes to the R parser,...

...;t get any search resuts. This seems to only be an issue when NOT (or a preceding -) are used. For example, both of these work: (other_text:"Collaborative tools") AND other_text:podcasts (other_text:"Collaborative tools") AND (other_text:podcasts) My use of parentheses is for precedence (I assume they work that way). I quickly looked at query_parser.y, but as I''ve never used racc (or yacc), it''s not apparent to me what should be happening. Thanks! Jen

Just a reminder that this remains an issue up to and including the latest syslinux 3.53-pre (0x473cfc9c). Additional testing suggests that implicit hostname/IP has never worked, ever since the common prefix suppression feature was added in version 3.00. -------- Original Message -------- Subject: pxelinux doesn't suppress common prefix if nothing precedes double colon Date: Sat, 25 Aug

...have identified which files that are common to every host, and then which files are common to any particular site. Finally, you have the files which are private to the node in question. What I was wondering was if it would be possible to have some sort of directory hierarchy which has some kind of precedence, or order. The following example tree explains it, regional/root/.ssh/authorized_keys regional/etc/nsswitch.conf siteA/etc/resolv.conf siteB/etc/resolv.conf node1/etc/motd node2/etc/motd Now, I would rather not write rules for every single file, I would like to write one generic rule that does t...

Gabe, The unary functions have the same precedence as normal SPECIALS (although the new unary forms take precedence over binary SPECIALS). So they are lower precedence than unary + and -. Yes, both of your examples are valid with this patch, here are the results and quoted forms to see the precedence. `%chr%` <- function(x) as.character(x)...

Thanks Bill. I appreciate that you are really trying to help me with my "precedence problem". Maybe I should clarify that I can live with it though. Anyway, it's always good to know how to make substitutions in the parse tree. Cheers, H. > > Bill Dunlap >...
