R’s built in functions. for some exercises, you might want to create a vectorized solution (i.e., avoiding loops), and or a (usually slowe ) non vectorized solution. however, the exercises do not aim to practise vectorization and speed, but rather defi. These exercises were originally developed for a second year undergraduate module at the university of warwick. the exercises are graded the first two sheets are intended to get users thinking in terms of vector and matrix operations whilst the later sheets involve writing functions. Exercise 5: adding or creating new data in your cancer data generate new columns called cases and deaths which sum up (literally add them together) the male and female values you have been given and overwrite the original cancer variable with the expanded version. Generate a vector (1; 1; 1; 1; 1; 2; : : : ; 4; 4)t of length 20, representing these conditions. (b) the scientist wants to do the 20 experiments in a completely random order; use sample() to reorder the elements of the vector from (a). (c) the scientist calls the conditions a, b, c and d.
