postgresql - convert character string into R integer vector -


i receive character string "{1,0,0,0,0,0}" created textual representation of vector (integer[]) postgresql , have cast r integer/numeric vector. there efficient way convert v r representation of vector? in advance.

v [1] "{1,0,0,0,0,0}"

class(v) [1] "character"

mode(v) [1] "character"

typeof(v) [1] "character"

if positive integer then:

as.integer(unlist(strsplit("{1,0,0,0,0}", "\\d+"))[-1])

if negative possibility:

as.integer(unlist(strsplit("{1,-3,0,0,0}", "[,{}]"))[-1])

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.
