[R] Null

[pcc]

This is probably a very simple question but I am completely stumped!I am
trying to do shapiro.wilk(x) test on a relatively small dataset(75) and each
time my variable and keeps coming out as 'NULL', and 

> shapiro.test(fcv)
Error in complete.cases(x) : no input has determined the number of cases

my text file looks like this:
