a)Write a function as a R code,my_function, to test if two given arguments,aandb, are both numeric. If they are, calculateaplusb. If they are not both numeric, print "the arguments were not both numeric".

Here's the outline of the required code. You need to enter the'missing code'

my_function 'missing code') {

missing code - the calculation if the above condition is TRUE

else

missing code -print "the arguments were not both numeric"

}

b)Call the function as follows to show that the function is working as required.

my_function (10, 20)

my_function (10,"cat")

3) Write a function, my_function, to test if two given arguments, a and b, are both numeric. If they are, calculate a plus b. If they are not both numeric, print \"the arguments were not both numeric\". Here's the outline of the required code. You need to enter the 'missing code ' my_function
