When setting the cutoff variance to something absurd like 40, I encountered the following error: `Error in svd(x, nu = 0, nv = k) : infinite or missing values in 'x'` Upon tracking down the problem, I saw that a dataframe had a column that contained the same number. This means that when I calculate: `(x - mean(x)) / (sqrt(sd(x)))`, I will get a `NaN` resulting in an error in the svd. The fix was to check for `NaN`s before proceeding with `svd` using a simple `is.na` function.
