i need calculate called mat (movie anual total), means % change in sales value between same day in 2 different year: id sales day month year 500 31 12 2015 100 1 1 2016 200 2 1 2016 ... 200 1 1 2017 does have idea how deal it? i want this: id sales day month yeas **mat** with way data set up, you're quite close. want group data month , day, order each group year, , take successive differences (assuming want mat sequential years) library(lubridate) library(dplyr) x <- data.frame(date = seq(as.date("2014-01-01"), as.date("2017-12-31"), = 1)) %>% mutate(day = day(date), month = month(date), year = year(date), sales = rnorm(nrow(.), mean = 100, sd = 5)) x %>% group_by(month, day) %>% arrange(month, day, year) %>% mutate(mat = c(na, diff(sales))) %>% ungroup() if wanting abl...

this code: .metismenu li a:hover{ background:#112542;} .metismenu li a:focus{ background:inherit;} when have clicked on a it's background-color being inherited , hovering mouse again on it's background-color not being #112542 until not clicking anywhere outside a remove focus it. there solution can change it's background-color without clicking outside , hovering mouse again? you can try :focus:hover state, in example : see fiddle .metismenu li a:focus:hover{ background:yellow;} .metismenu li a:hover{ background:#112542;} .metismenu li a:focus{ background:inherit;} .metismenu li a:focus:hover{ background:yellow;} <div class="metismenu"> <ul> <li><a href="#!">link test</a></li> </ul> </div>

i have trouble lsf alljoyn 15.04, build lsf in ubuntu 16.04 success cannot run app. i'm receiving notification whenever run ./lighting_controller_client_sample in service_framework-15.04/core/service_framework/build/linux/standard_core_library/lighting_controller_client/samples : ./lighting_controller_client_sample: symbol lookup error: ./lighting_controller_client_sample: undefined symbol: _zn3ajn15_remoteendpoint17pushmessagerouterern3qcc10managedobjins_8_messageeeerm how can fix it? sounds can't find cpp libs (the .a , .so files). in case need define ld_library_path. for example, if building alljoyn scons, define following environment variable before running sample. export ld_library_path=/core/alljoyn/build/linux/x86_64/release/dist/cpp/lib or export ld_library_path=/core/alljoyn/build/linux/x86_64/debug/dist/cpp/lib that @ least allow find alljoyn cpp lib files.

i have uiwebview inside ios application , loads responsive website webview, developed in asp.net . website has button choose video device photo library , button upload video. in till ios version 10.2 uploading files server. apple introduce new version ios 10.3 new file system apfs before hfs+ file system. in ios 10.3 doesnot allow application read video file , 0kb size uploaded server. because app doesnot have read permission file. how can allow file system permission read file app.is there can added info.plist do stuck kind of issue. thanks the problem related bug in uiwebview makes file input have multiple attribute set automatically. the solution ios 10.3 use wkwebview instead, not add multiple attribute automatically. it's old ios apps use uiwebview guess reason why there not many bug reports on web related problem.

the idea make request (in js) fetch documents field being contained in given array if array defined, or documents if array not defined. i wondered if there elegant mean give $in argument parameter nullifies behavior, can used one-liner. take idea have make kind of conditional request more elegant. here snippet using mongoose: let query = somemodel.find(); if (somearray) { query = query.where(somefield).in(somearray); } query.exec(); sure works, requires store query in variable, not cool. aggregation might help. let itemvalues = somearray || []; somemodel.aggregate([ { $match: { "somefield": { [itemvalues.length > 0 ? "$in" : "$nin"]: itemvalues} } } ]).exec()

in angular 2 use ngrx , have actions , reducers. example of actions : import { action } '@ngrx/store'; export const actiontypes = { action_1: type('actions 1'), action_2: type('actions 2'), }; export class actionone implements action { public type = actiontypes.action_1; constructor(public payload: any) { } } export class actiontwo implements action { public type = actiontypes.action_2; } export type actions = actionone | actiontwo; so, actions has payload, others - no, , actions union type, can actionone or actiontwo . in me reducer have error: property 'payload' not exist on type 'actions' property 'payload' not exist on type 'actiontwo'. reducer this: export function reducer(state = initialstate, action: actions): istate { switch (action.type) { case actions.actiontypes.action_1: { return object.assign({}, state, { data: action.payload, }); } case ... } } ...

i trying sum combination of values list of tuples in dictionary. example, dictionary contains: dict = {1: [(2, 2), (4, 3), (6, 1), (7, 1), (8, 3)], 2: [(4, 1), (5, 3), (1, 2)],...} and goes on multiple entries. i'm trying sum second value of tuples each entry in many combinations sum maximum of 4. entry 1, desired output be: {1: [(2, 6, 3), (2, 7, 3), (4, 6, 4), (4, 7, 4), (6, 7, 2), (8, 6, 4), (8, 7, 4)] where third value in tuple sum of combinations of second value of previous tuples, , first , second values of tuple associated first values of previous tuples. i have tried following code: for key, value in dict.items(): object1 = key mylist = value tup in mylist: object2 = tup[0] pair = tup[1] combo = itertools.combinations(tup[1],2) sum = {k:sum(j _,j in v) k,v in combo} if sum <= 4: print(sum) and error 'numpy.float64' object not iterable i think error stems "combo...

i have dataset interested in looking @ score on test , percentage of people experiencing event: dat <- data.frame(score = 1:7, n.event = c(263,5177,3599,21399,16228,10345,1452), n.total = c(877,15725,13453,51226,32147,26393,7875), percentage = c(30,33,27,42,50,39,18)) i can plot percentages on graph this: ggplot(data=dat, aes(x=score, y=percentage)) + geom_line() + geom_text(aes(label = paste0(dat$percentage,"%"))) or can plot fractions this: ggplot(data=dat, aes(x=score, y=percentage)) + geom_line() + geom_text(aes(label = paste0("frac(",dat$n.event, ",", dat$n.total, ")")),parse = true) but want have both of them side side. doesn't work: ggplot(data=dat, aes(x=score, y=percentage)) + geom_line() + geom_text(aes(label = paste0(dat$percentage,"%","frac(",dat$n.event, ",", dat$n.total, ")")),parse = true) i error: er...

i'm trying following apdu: 00 a4 00 00 02 3f 00 00 everything according iso 7816-4 (7.1.1), execution fails sw 0x6a86 (incorrect parameters p1-p2) why? i'm doing wrong? standard states follows: if p1 set '00', card knows whether file select mf, df or ef, either because of specific encoding of file identifier, or because of command processing context. ... if p2 set '00' , command data field absent or set '3f00', mf shall selected. i checked visa/mc cards , apdu fails on of them. your idea correct, difficult understand without background: smartcard either native cards (these have file system including mf, of course) or javacards / open plattform cards (which have none). select command both types share, select aid (application id), i. e. selecting application (p1 = 4, command data field contains aid). emv compliant cards can realized on both, apparently have latter.
