Conditional handling of (non-distributable) absent data
# this project might have some confidential data that cannot be distributed
# Rather than break the program, or worse, ask replicators to comment out lines,
# provide a clean skip of those things, or even an alternate output (robustness check?)
basepath <- c("/path/to/project")
# or :
# basepath <- here::here()
# set filepaths relative to basepath

Hamming distance
The \emph{Hamming} metric on $\mscr X^n$ is $H: \mscr X^n \times \mscr X^n \rightarrow \ZZ^{\geq 0}$, defined by $H(\ul x,\ul x') =\# \{i \mid x_i\neq x'_i\}$. %In other words, the Hamming distance counts the number of entries that differ between $X$ and $X'$.
