In Shiny for R, why does Sys.Date() return yesterday's date inside a dateInput? -


i have dateinput in ui.r follows: 

dateinput("asofdatetime", label = "as of", value = sys.date(), max = sys.date())

for 2015-05-15, gives dateinput default value of 2015-05-14.

however, when run sys.date() in console on 2015-05-15, correct value: 2015-05-15.

why shiny give yesterday's date inside app?

that sound weird. starting on shiny not know sure.

could be

  1. timezone?? maybe sys.timezone() different on servers?

    have tried formatting date timezone?

  2. caching problem??

    could value cached old instance? take running within shinyserver{ ... code} not above. try rebuild in dashboard?

but here solution

set value null (see helpfile)

value starting date. either date object, or string in yyyy-mm-dd format. if null (the default), use current date in client's time zone.

it default date in timezone.

dateinput("asofdatetime", label = "as of",                                      value = null, max = sys.date())

gave me today's date

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
