...least about the following query!) Reading the draft proofs of an article I've been asked to look through, I find the typesetter has set what would normally be entered as source("xyz.R") or source('xyz.R') as source(`xyz.R') i.e. it has come out with an opening backquote, then xyz.R, then a closing forward quote. I suspect the intervention of "intelligent" software (? la Word's "clever quotes"). Well, the cure is clear and I'm not asking about that. But I got curious about what role the backquote might play in R syntax (if any). As a st...

Thanks to Bill Dunlap for the clarification. On follow-up it turns out that this will be an issue for many if not most of the routines in the survival package: a lot of them look at the terms structure and make use of the dimnames of attr(terms, 'factors'), which also keeps the unneeded backquotes. Others use the term.labels attribute. To dodge this I will need to create a fixterms() routine which I call at the top of every single routine in the library. Is there a chance for a fix at a higher level? Terry T. On 03/05/2018 03:55 PM, William Dunlap wrote: > I believe this has to...

I believe this has to do terms() making "term.labels" (hence the dimnames of "factors") with deparse(), so that the backquotes are included for non-syntactic names. The backquotes are not in the column names of the input data.frame (nor model frame) so you get a mismatch when subscripting the data.frame or model.frame with elements of terms()$term.labels. I think you can avoid the problem by adding right after ll &l...

That's more or less right. We wrote a terms.merMod method, which accesses the terms component of the @frame slot, which we have modified upstream ... Do you mean term.labels rather than term.names? BTW ?terms.object says (under the "term.labels" element): Non-syntactic names will be quoted by backticks: this makes it easier to re-construct the formula from the term

I''ve done tons of searching on this so I apologize if this is one of those common knowledge things. I am relying on Kernel#` and Kernel#system to run some command line utilities in my Rails app. This worked great until I moved to Apache (win32). When running FCGI, neither of these methods work (both return nil). When running CGI, system seems to work, but ` doesn''t. I have

Since my previous question didn''t get much attention, I thought I''d make the subject more expressive. I didn''t realize the list had this much traffic. Is anyone using system or "backquote" to run commands in Rails? These work fine in webrick, but both return nil when running in Apache FCGI. In CGI mode, system seems to work, but backquote doesn''t. Any ideas? Been banging my head on the wall for a while. BTW, this is on Windows. Mark -------------- next part ------...

Dear R-devel, There is a new feature in R-devel, which explicitly refers to LISP @ operator for splicing. > The backquote function bquote() has a new argument splice to enable splicing a computed list of values into an expression, like ,@ in LISP's backquote. Although the most upvoted SO question asking for exactly LISP's @ functionality in R doesn't seems to be addressed by this new feature. Is it possi...

Dear List, Is it possible to have function names like ? (unicode universal quantifier)? This question is inspired by agda source code, which supports this. http://www.cs.nott.ac.uk/~nad/listings/lib-0.4/Algebra.html It would be handy to use. My guess is, however, that it's not supportet in R. Regards, Steve

DTraceToolkit has a dtrace script (Proc/pidpersec.d) that refers to a variable mpid as below profile:::tick-1sec { printf("%-22Y %8d %6d\n", walltimestamp, `mpid, pids); pids = 0; } Where is `mpid getting picked from (it isn''t declared anywhere else)? What does the character ` in `mpid signify? I do not see any reference to this variable in the dtrace
