Match and replace operation in data frame in R -


let's dataset following:

john   na    kaira    carry  john  na maya   sam   maya leo    paty  leo tinker na    tinker fabo   leo   maya

i have dataset:

john   1 carry  2 maya   3 leo    4 tinker 5 fabo   6 sam    7 paty   8  kaira  9

i want match values of above table (df2) first table (df1) final table (df) looks following:

1   na   9    2   1    na 3   7    3 4   8    4 5   na   5 6   4    3

could do

df1[] <- match(unlist(df1), df2$v1) #   v1 v2 v3 # 1  1 na  9 # 2  2  1 na # 3  3 na  3 # 4  4  8  4 # 5  5 na  5 # 6  6  4  3

if numbers in df2 not in order, abit adjust code be

df1[] <- df2[match(unlist(df1), df2$v1), 2]

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.
