@harry, on SO, posting samples in images is NOT encouraged, so please proper samples of input and output in code tags and let us know then.

Try to avoid inserting of pictures and check the solution:
dummy<-data.frame(A=sample(c("buy","sell"),100,replace = T),
B=sample(c("buy","sell"),100,replace = T),
C=sample(c("buy","sell"),100,replace = T),
D=sample(c("buy","sell"),100,replace = T),
E=sample(c("buy","sell"),100,replace = T),
G=sample(c("buy","sell"),100,replace = T))
head(dummy)
A B C D E G
1 buy buy sell sell buy buy
2 buy buy buy buy buy buy
3 buy sell buy buy sell buy
4 sell buy buy sell buy sell
5 sell sell sell sell sell sell
6 sell sell buy sell sell sell
Now apply the function with sapply on selected columns from 1:4 i.e., A to D
sapply(dummy[1:4], function(x) table((x)))
OUTPUT :
A B C D
buy 50 53 53 51
sell 50 47 47 49
