We do not have to use the chunk option names given in knitr; we can set
aliases for them. The aliases are a named character vector; the names are
aliases and the elements in this vector are the real option names.
Usage
set_alias(...)
Arguments
...
named arguments (argument names are aliases, and argument values
are real chunk options)
Value
NULL (opts_knit$get('aliases') is modified as the side effect)
Examples
set_alias(w = "fig.width", h = "fig.height")
# then we can use options w and h in chunk headers instead of fig.width and
# fig.height
