i have class has member defined as: float u[2][2]; now have accessor function , return reference array. so, have like: const float & [2][2] mat() const { return u; } is there way return using kind o syntax rather pointer syntax (i think makes things more explicit). it's awkward, but: const float (&mat() const)[2][2] { return u; } using typedef or decltype might better, eg: const decltype(u) &mat() const { return u; } or: using mat22 = float[2][2]; const mat22 &mat() const { return u; } (this latter 1 suggested daniel h. in comments). or, in c++14, just: const auto &mat() const { return u; }

i have 2x2x2 factorial design 1 random effect. data (dat) follows: colour size level marbles set blue large low 80 1 blue large high 9 2 blue small low 91 1 blue small high 2 1 white large low 80 2 white large high 9 1 white small low 91 2 white small high 2 1 i want plot 2 models: mod1 <- lmer(marbles ~ colour + size + level + colour:size + colour:level + size:level + (1|set), data = dat) mod2 <- lmer(marbles ~ colour + size + level +(1|set), data = dat) i use following code plots: pd <- position_dodge(0.82) ggplot(dat, aes(x=colour, y=marbles, fill = level)) + theme_bw() + stat_summary(geom="bar", fun.y=mean, position = "dodge") + stat_summary(geom="errorbar", fun.data=mean_cl_boot, position = pd)+ + facet_grid(~size) i'm unsure on how replace terms coefficients model estimates. ideas on how can plot ...

i'm making top-down shooter android platform , i'm trying screen portrayed in added image( orange rectangles virtual buttons). following code being run before game starts change game window size fit device's screen: ///display properties display_width=display_get_width(); display_height=display_get_height(); ideal_width=0; ideal_height=display_height; aspect_ratio=display_width/display_height; ideal_width=round(ideal_height*aspect_ratio); //ideal_height=round(ideal_width / aspect_ratio); //perfect pixel scaling if(display_width mod ideal_width != 0) { var d = round(display_width/ideal_width); ideal_width=display_width/d; } if(display_height mod ideal_height != 0) { var d = round(display_height/ideal_height); ideal_height=display_height/d; } //check odd numbers if(ideal_width & 1) ideal_width++; if(ideal_height & 1) ideal_height++; for(var i=1; i<=room_last; i++) { if(room_exists(i)) { room_set_view(i,0,true,0,0,720,1280,60,60,720,1280,0,0,0,0,-...

i have saga export function* mysaga(api, action) { const response = yield call(api.service, action); yield put(navactions.goto('page', { success: response.ok })); } that calls api , return value navigate screen passing api call result ( response.ok ). it('test', () => { // ... const gen = mysaga(api, action); const step = () => gen.next().value; // doesn't run api const response = call(api.service, {}); expect(step()).tomatchobject(response); // ok // error, cannot read property 'ok' of undefined expect(step()).tomatchobject( put(navactions.goto('page', { success: response.ok })) ); }); since it's not running api call response doesn't defined. i don't know should test scenario. how test second step of saga? by default, yield expression resolves whatever yielded. however, can pass value gen.next method , yield expression resolved passed there. so should trick (untested): con...
