Aligning plots to the center of the box() in R shiny dashboard -


the script below creates 2 plots within 2 boxes in r shiny dashboard page aligned right of box, wish align these plots center of box.these packages minimum required packages create given plots. please help. 

## app.r ## library(shiny) library(shinydashboard) library(bupar) library(edear) library(eventdatar) library(processmapr) library(processmonitr) library(xesreadr) library(petrinetr)  ui <- dashboardpage( dashboardheader( ), dashboardsidebar( width = 0 ), dashboardbody( box(title = "process map", status = "primary",height = "575", solidheader =  t,patients %>% process_map(),align = "left"), box(title = "resource map", status = "primary",height = "575", solidheader =  t, resource_map(patients, render = t)) ) )  server <- function(input, output) { }  shinyapp(ui, server)

enter image description here

the problem seems htmlwidgets initialized 960 pixels width or so. 2 ways override be:

pmap <- patients %>% process_map() pmap$width <- "100%" rmap <- resource_map(patients, render = t) rmap$width <- "100%" ui <- dashboardpage(   dashboardheader(),   dashboardsidebar(     width = 0   ),   dashboardbody(     box(       title = "process map",        status = "primary",height = "575",        solidheader = t,       pmap,       align = "left"),     box(       title = "resource map",        status = "primary",       height = "575",        solidheader = t,        rmap     )   ) )

or

ui <- dashboardpage(   dashboardheader(),   dashboardsidebar(     width = 0   ),   dashboardbody(     tags$head(tags$style(html(".grviz { width:100%!important;}"))),       box(       title = "process map",        status = "primary",height = "575",        solidheader = t,       patients %>% process_map(),       align = "left"),     box(       title = "resource map",        status = "primary",       height = "575",        solidheader = t,        resource_map(patients, render = t)     )   ) )

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
