Checking a column of a matrix for numbers greater than 4 in r

I am trying to create an if statement with the condition "if any numbers in the column [,1] of Matrix B are greater than 4 do this......"

I am unsure of how to check the whole column.

So far I have managed to find out whether it is true or false by doing this:

B[,1] > 4 

and it comes back with:

FALSE TRUE TRUE TRUE

I want to make it so if at least one statement came back as "TRUE" it would carry out the 'if' statement:

if ((B[,1] > 4) == TRUE){
  Move <- append(Move, 5)
}

This comes up with the Warning message:

In if ((B[, 1] > 4) == TRUE) Move :
  the condition has length > 1 and only the first element will be used

How should I code it to check all the values in the column? I hope I have made my problem clear and any help would be appreciated.
