in r, have list of 11 dataframes named list1. every dataframe has same structure: names col2 col3 name1 1 10 name2 2 22 name4 3 40 i have dataframe called table1 looking this names col4 col5 name1 ... ... name2 ... ... name3 ... ... now want take subset of original 11 dataframes. each dataframe want print lines there match between values in 'names' column of dataframe , names column in table1. in case, new dataframe should this names col2 col3 name1 1 10 name2 2 22 all new dataframe should appended again in list2. work lapply , match function? mylist2 <- lapply(mylist1, function(...){ match(...) } you can this required.list = lapply(list1, function(x) subset(x, names %in% table1$names))

i'm using palette class programmatically dominant color image want use status bar , toolbar. according material design guidelines, status bar color should 2 shades darker toolbar color. bitmap bitmap = ((bitmapdrawable) ((imageview)mimageview).getdrawable()).getbitmap(); if (bitmap != null) { palette = palette.generate(bitmap); vibrantswatch = palette.getvibrantswatch(); darkvibrantswatch = palette.getdarkvibrantswatch(); } for darker color i'm using darkvibrantswatch , lighter color, i'm using vibrantswatch. in of cases, these turn out different each other , hence becoming unusable. there workaround this? maybe if possible 1 color, darkvibrantswatch, , programmatically generate color 2 shades lighter? i'm not sure getting 2 shades lighter can play around shade_factor , see if can achieve want. private int getdarkershade(int color) { return color.rgb((int)(shade_factor * color.red(color)), (i...

given 2 functions, need find intersection points , show them on graph. particular problem, functions are: f(x) = - (x - 2) ^ 2, g(x) = x/(x+1). so far, have following: plot[{-(x - 2)^2 + 4, x/(x + 1)}, {x, 0, 4}, filling -> {1 -> {{2}, {white, lightblue}}}] nsolve[-(x - 2)^2 + 4 == x/(x + 1), {x, y}] but have no idea how show points on graph. how do that? you can use epilog option add graphics primitives plot: intersections = {x, y} /. nsolve[y == -(x - 2)^2 + 4 && y == x/(x + 1), {x, y}]; plot[{-(x - 2)^2 + 4, x/(x + 1)}, {x, 0, 4}, filling -> {1 -> {{2}, {white, lightblue}}}, epilog -> {red, point[intersections]}]

i've decided build own navigation scratch. i using jquery if/else handle interaction. the issue having detecting ul li clicked, , doing based upon result (using $this). can first depth level function correctly, ie first ul li on-click opens first sub-child ul class .c (c = child), not next depth level below that, ie second ul li doesn't open second sub-child ul class .sc (sc = sub child). here fiddle. here live example: !function(n){ $('ul li + ul').prev('a').append('<span class=ai></span>'); $('ul li a').on('click', function(n) { if($('.c').css('display') == 'none') { $this = $(this); $(".c").slidetoggle(); $this.find('span.ai').toggleclass('st'); n.preventdefault(); } else if($(this).is('ul li.p a')) { $this = $(this); $(".c").slidetoggle(); $this.find('span.ai').toggleclass(...

i trying understand asyncio library, using sockets. have written code in attempt gain understanding, i wanted run sender , receiver sockets asynchrounously. got point data sent till last one, have run 1 more loop. looking @ how this, found this link stackoverflow , implemented below -- going on here? there better/more sane way call stop followed run_forever ? the documentation stop() in event loop is: stop running event loop. every callback scheduled before stop() called run. callbacks scheduled after stop() called not run. however, callbacks run if run_forever() called again later. and run_forever() 's documentation is: run until stop() called. questions: why in world run_forever way run_once ? doesn't make sense is there better way this? does code reasonable way program asyncio library? is there better way add tasks event loop besides asyncio.async() ? loop.create_task gives error on linux system. https://gist.github.com/cloudformdes...
