You are not asking for a Decrete [sic]  (descrete) value check but
rather if the numbers are intergers.   

Try this: 

# from the ?is.integer help page 
is.wholenumber <- 
    function(x, tol = .Machine$double.eps^0.5)  abs(x - round(x)) < tol 


aa  <- data.frame( na = c( 1, 3.4, 5, 5.6), nb = c(2.4, 4, 6, 6.7)) 
ww  <- data.frame(  is.wholenumber(aa)) 
cbind(aa, ww)
