R converting a single week row, to 7 day rows -


i've seen few similar examples , threads online morning, nothing find quite particular case. have dataframe looks this:

    week       income   views   partner     09/07/15   2000     345     bob     09/07/15   460      11980   jane     08/31/15   304      678     mark

what need each "week row" replicated each day within week. don't need worry how alter other variables divided 7, can perform operations without assistance. having trouble expanding week row 7 rows total describe each day within week, so:

    week       income   views   partner     09/07/15   2000     345     bob     09/08/15   2000     345     bob     09/09/15   2000     345     bob     09/10/15   2000     345     bob     09/11/15   2000     345     bob     09/12/15   2000     345     bob     09/13/15   2000     345     bob     09/07/15   460      11980   jane     09/08/15   460      11980   jane     09/09/15   460      11980   jane     09/10/15   460      11980   jane     09/11/15   460      11980   jane     09/12/15   460      11980   jane     09/13/15   460      11980   jane     08/31/15   304      678     mark     09/01/15   304      678     mark     09/02/15   304      678     mark     09/03/15   304      678     mark     09/04/15   304      678     mark     09/05/15   304      678     mark     09/06/15   304      678     mark

like said other data points can left @ na (i can na.locf easily) or have them copied down columns.

thanks in advance!

the code below uses mapply create new rows each combination of week , partner. then, wrap in do.call(rbind, ...) put each subgroup single data frame. i've left original week column in final output illustation, can removed.

# sample data dat = read.table(text="    week       income   views   partner     09/07/2015   2000     345     bob     09/07/2015   460      11980   jane     08/31/2015   304      678     mark"  , header=true, stringsasfactors=false) dat$week = as.date(dat$week, "%m/%d/%y")  newdat = do.call(rbind,         mapply(function(w,p) {           data.frame(day=seq(w, w+6, 1), dat[dat$week==w & dat$partner==p, ])         }, dat$week, dat$partner, simplify=false))  newdat           day       week income views partner 1  2015-09-07 2015-09-07   2000   345     bob 2  2015-09-08 2015-09-07   2000   345     bob 3  2015-09-09 2015-09-07   2000   345     bob 4  2015-09-10 2015-09-07   2000   345     bob 5  2015-09-11 2015-09-07   2000   345     bob 6  2015-09-12 2015-09-07   2000   345     bob 7  2015-09-13 2015-09-07   2000   345     bob 8  2015-09-07 2015-09-07    460 11980    jane 9  2015-09-08 2015-09-07    460 11980    jane 10 2015-09-09 2015-09-07    460 11980    jane 11 2015-09-10 2015-09-07    460 11980    jane 12 2015-09-11 2015-09-07    460 11980    jane 13 2015-09-12 2015-09-07    460 11980    jane 14 2015-09-13 2015-09-07    460 11980    jane 15 2015-08-31 2015-08-31    304   678    mark 16 2015-09-01 2015-08-31    304   678    mark 17 2015-09-02 2015-08-31    304   678    mark 18 2015-09-03 2015-08-31    304   678    mark 19 2015-09-04 2015-08-31    304   678    mark 20 2015-09-05 2015-08-31    304   678    mark 21 2015-09-06 2015-08-31    304   678    mark

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
