> I don't understand the warning I get when executing the following code:
> x <- rnorm(100)
> h <- hist(x, plot= FALSE, freq = FALSE)

The warning is
"Warning message:
In hist.default(x, plot = FALSE, freq = FALSE) :
  argument ‘freq’ is not made use of"

The explanation is pretty simple. 

freq determines whether or not the histogram is of counts or probability 
densities.  Since you used plot=FALSE, you aren't plotting anything, so 
freq does nothing.
