i create bins variable numbers per category name inside function. having difficulties related using category name provided parameter inside function. in dplyr approach, each observation gets bin in new column. pass colgroup parameter inside mutate instead of writing name of column directly, , establish bin lower , upper limits each group (colgroup) in pseudocode. maybe data.table approach better. set.seed(10) b<-(rnorm(10, sd=1,mean=10)) y<-runif(3) pr<-y/sum(y) names<-unlist(lapply(mapply(rep, letters[1:3], 1:3), function (x) paste0(x, collapse = "") ) ) x <- sample(names, 10, replace=true, prob=pr) df<-data.frame(name=x,numbers=b) df #working without bin limits per category (not desired) #and using "numbers" in cut (not desired) binfunction1 <- function(df, colgroup1, varcount,binsize) { new<-df %>% group_by_(colgroup1) %>% mutate(bin = cut(numbers, breaks <- c(seq(7, 15, = binsize)), # limits colgroup not imp

i have multi-part question: my journey began when trying figure out if can have descending/ascending primary keys in oracle sql. there doesn't seem syntax along lines of create table mytab (id int primary key desc); or create table mytab (id int, constraint pk primary key(id desc)); later learned oracle implicitly creates index primary key enforce constraints. figured create index it, , make index descending. create index myind on mytab (id desc); this worked, when did query see indices existed got this: > select index_name user_indexes table_name = 'mytab'; index_name ------------------------------ sys_c0011939 myind i see implicitly created index there own index... tried see if rid of implicitly created index creating index primary key during table create: create table mytab (id int primary key using index (create index myind on mytab (id asc))); this worked: > select index_name user_indexes table_name = 'mytab'; index_name ----

i'm trying create component displays subset of items passed it. so far have 'sublist' component named slots follows: ... data: () => ({ startitem : 0 }) ... <template> <div> <slot v-for="ctr in maxitems" :name="'s-' + (ctr + startitem - 1)"></slot> </div> </template> in parent following: <sublist :max-items="5"> <div v-for="(i,index) in items" :slot="'s-'+index"> {{index}} </div> </sublist> when loads, renders fine: 0 1 2 3 4 however when increment startitem in sublist component, output becomes: 5 1 2 3 4 so removes 0th slot , stuffs slot 5 in place. proper way replace slots or make them "dynamic"? i'm using vuejs 2.4.2 thanks @steveholgado found answer: had add :key attribute in parent v-for , wrap each slot in child in own div: <template> <div&g

i'm importing a lot of images, >50,000, neto website , they're not importing correctly; @ bottom of images, horizontal grey bars rendered instead of rest of image. since affects bottom , seemingly in sequence best guess it's timing; server cuts connection because it's timing out, cms accepts , processes image though it's incomplete. example here. let me know if thoughts! :)

i use git blame secondary form of documentation. it's useful check why commit made, , when , whom. but history of particular line gets lost. situations might happen: a change made, reverted. someone re-indents file , commits it. later standard indentation restored , committed. someone copies files new branch/repo no history. still have original history in branch, want merge new branch. in these cases git blame show latest changes file, not useful. e.g. "restore indentation" or "revert commit #123" or "initial commit: files". is there way hint git blame more interested in older history new one? here situation: ... - - b - c commit has annotations lines in file. commit b reindented entire file. commit c (possibly revert) restores file how in commit a. i wondering if perform magical git merge priority parent: .-------. / \ ... - - b - c - d commit d tells git priority history git blame follow.

i want store object in vue, should available entire instance , not reactive. (with reactive) use 'data' this: new vue({ data: myobject }) but in fact myobject don't need change think making reactive bad. there method this? you can use vue instance properties. there may data/utilities you’d use in many components, don’t want pollute global scope. in these cases, can make them available each vue instance defining them on prototype: vue.prototype.$appname = 'my app' now $appname available on vue instances, before creation. if run: new vue({ beforecreate: function () { console.log(this.$appname) } }) reference: link or you can use vuex state data property , define mutations if want change value.

i have started angular4 , have came against conceptual problem. async pipe (used in combination *ngfor in case) meant subscribe observable , away manual subscriptions. looking @ examples on web: case 1: binding observable contains single items such observable<user> case 2: binding observable contains arrays of items such observable<user[]> case 3: variations of 1 , 2 subject, promise or behavioursubject (example of case 1 single item: http://briantroncone.com/?p=623 ) (example of case 2 array: http://www.concretepage.com/angular-2/angular-2-async-pipe-example ) conceptually ngfor iterates on enumerable , i'm assuming enumerable item emitted observable , not observable itself. so *ngfor="let user of users" going work on observable<user[]> , not observable<user> ? the *ngfor triggered each item arrives observable? if case how can bind observable of item , not item[] , how ngfor iterate on item when not enumerable? thank

i'm wondering, recursion example: squaresrec :: [double] -> [double] squaresrec [] = [] squaresrec (x:xs) = x*x : squaresrec xs why on recursive case, there no bracket? shouldn't suppose this: squaresrec :: [double] -> [double] squaresrec [] = [] squaresrec [x:xs] = x*x : squaresrec xs i know not work. wondering explanation behind it. [] matches empty list. [1] matches list containing 1 element, , must number equal one. note [1] syntactic sugar (1:[]) , i.e. matches is: list beginning number 1 , followed list empty... complicated way of saying “a list containing single element 1 ”. (x:xs) matches list begins x , followed xs (and may contain number of elements, possibly zero). i.e. pattern matches list at least 1 element. [x:xs] matches again list contains exactly 1 element, , element should match pattern (x:xs) . (which doesn't make sense type-wise, because lists contain double -num
