Dear R Admins, I received an unsolicited e-mail from BlueInference as an R user. Does it mean that R that our e-mails (and names) is sharing it's user database with third parties without our consent? Or perhaps the BlueInference guys are using an e-mail address miner to get our contact details? [SNIP] Dear Gorden Jemwa, As a fellow R user, I am s...

I agree that it is a problem that we're not inferring from Pat<> patterns, and that not all instructions are expressible with patterns, but I'd rather we solve *those* problems than throw out inference. After discussing this, we have reached a workable compromise. Here's what we'll do: The inferred instruction properties will b...

The bio.infer package contains a data frame /usr/lib/R/library/bio.infer/data/itis.ttable.rda that needs to be modified. After loading the bio.infer package and attaching the data frame with the data() function, I wrote the data frame to a text file. After adding another row to the data frame I applied read....

...s<"X86", [i32, f32], 32, (add GR32, FR32)>; I thought this would be a harmless thing to do since the new register class is not being referenced anywhere. I was wrong, it caused all kinds of assertion failures from tablegen's isel pattern generator. It appears that tablegen is inferring the 'type' of an individual register by enumerating all the register classes it appears in. Some things, like using implicit defs in SDNodes, only works for registers with a unique type. My WIDE32 class caused GR32 registers to no longer have a unique type, breaking the world. This s...

Hello, I looked for R packages which focused on order-restricted statistical inference, but I could find only the isoreg() function. I would need to test whether the means in my (repeated measures) data follow a given order, e.g. A<B=C<D. I took a look at the monograph by Barlow et al. (1972) on this topic and found that for my case the null hypothesis is always A=B=C=D...

If all instructions had patterns, and we could accurately infer properties, it wouldn't be a problem. Ok, I agree with that. I think it's crazy that we still can't write a pattern...

...scopes, i.e. it provides an order to the binding and visibility of preceding variables.". I have included the recursive Common LISP function in which let* block appears and a straighforward R port. Thank you, Gabriel Baud-Bovy The let* block appears in the following LISP function: (defun infer (goal subsitution kb) (if(null kb) (make-empty-stream) (let* ((assertion (rename-variable (car kb))) ; ********* (match ([...]))) (if (equal match 'failed) (infer goal substitutions (cdr kb)) (if (rulep assertion)...

All, TableGen likes to infer the MCID::UnmodeledSideEffects flag from an instruction's pattern. When an instruction doesn't have a pattern, it is assumed to have side effects. It's possible to override this behavior by setting neverHasSideEffects = 1. It was originally the intention that most instructions have pa...

In the following snippet, can''t the includes being inferred from the where clause? Order.includes(:items).where(:items => { :category => [1,2,3] }) Can''t the includes be inferred from the where clause?

Good afternoon! My question is more of a "is there a package for doing........?" an inference regarding the mean, median, regression estimates, etc. by using the information from dual frame surveys? (this methodology is based on the work of BANKIER 1986, SKINNER 1991, LOHR and RAO 2000...) If one has 2 independent studies which both independently measure a trait of a population, b...

Dear R mailing list, I have a dataset with genotypes from trios and I would like to infer haplotypes for each mother, father and child. The package that I could find that can do this is tdthap. But when the mother is homozygous (e.g., 2/2) the haplotype is called as not possible to infer (0); I would prefer for it to call the genotype (2). From what I understand it is doing what I...

Hi Devs, I am a PhD student at Indiana University. I am interested in working on the project on function attribute inference. My current research direction involves runtime binary optimization using JIT compilation from a lifted LLVM IR. I am hoping various runtime information coupled with static analysis on the IR can provide better avenues for runtime code JITTIng (akin to PGO). Anyway I think the project on funct...
