R error: cannot coerce type 'closure' to vector of type 'double'

Question

I\'m getting an error in my R program that says:

Error in as.double(x) : cannot coerce type \'closure\' to vector of type \'double\'

Answer 1

Change:

sd.norm = sd(sample)/sqrt(n)

to:

sd.norm = sd(the.sample)/sqrt(n)

You are trying to use the function sample (a closure) as a number (double)
