assume have dataset containing 2 categorical predictor variables (a,b) , binary target (y) variable. > df <- data.frame( > = factor(c("cat1","cat2","cat3","cat1","cat2")), > b = factor(c("cat1","cat1","cat3","cat2","cat2")), > y = factor(c(t,f,t,f,t)) > ) the following logical relations exist in data: if (a = cat3) (b = cat3 , y = true) else if (a = b) (y = true) else y = false i want use glm build model dataset. glm automatically apply reference cell coding on categorical variables , b. take care of finding right number of codes each factor variable, no alias variables introduced (explained here ). however can happen, dataset above, linear relationship exists between 1 reference code generated variable , 1 reference code of variable b. see output of model: > model <- glm(y ~ ., family=binomial(link='logit'), data=df) > summary

i know question has been asked many times answers didn't solve problem. want delete nodes in label telephonenumber , relationships (millions). have tried first deleting relationships way: match (:person)-[r:has_telephone_number]->(:telephonenumber) delete r but after amount of time error gc overhead limit exceeded . have tried limiting query this: match (:person)-[r:has_telephone_number]->(:telephonenumber) r limit 100 delete r but same error. have tried way: match (t:telephonenumber) optional match (t)-[r]-() delete t,r but same error again. how can delete nodes in label , relationships without exceeding garbage collector overhead limit? you may want take advantage of apoc procedures apoc.periodic.commit() . also, since you're wanting delete nodes, detach delete help, delete relationships node , delete node itself. an example of usage might be: call apoc.periodic.commit(" match (tel:telephonenumber) tel limit {limit} detach delete tel re

i'm beginner scala developer having problems coding exercise (5.12) taken book "functional programming in scala" paul chiusano. i have function here, called unfold , takes initial state , function producing stream next states: def unfold[a,s](z: s)(f: s => option[(a,s)]): stream[a] = f(z) match { case some((h,t)) => h #:: unfold(t)(f) case _ => stream.empty } for example, function 1 can create infinite stream of objects, e.g. def constant[a](a: a): stream[a] = unfold(a)(_ => some(a,a)) now, want create fibonacci sequence, type: def fibs: stream[int] = unfold((0,1))((a,b) => some(a,(b,a+b))) i these errors: missing parameter type b expression of type some[((int,int),(nothing,string))] doesn't conform expected type option[(a_,(int,int))] if use case keyword inside anonymous function passed unfold , like: { case (a,b) => some(a,(b,a+b))} everything's fine. so question is: what's difference between 2 implemen

since can have multiple steps run sequentially in mutation, can have conditional if statement in graphql later steps run if result previous step meets condition? e.g. mutation upsertlogin($idtoken: string!, $email: string!, $username: string!) { user(email: $email, username: $username) { id } // next step if no id from previous step createuser(email: $email, username: $username) { id } } no, graphql doesn't support kind of conditional execution. thing explicitly supported throwing error in 1 mutation in order prevent remainder of mutations running. works because mutations run sequentially. in theory implement conditionals mention writing , reading context, shared between resolvers, not recommend doing so, because implementations of graphql declare context immutable.
