skipcode {cacher} | R Documentation |
Specify R expressions whose evaluation should be skipped
skipcode(num, append = TRUE)
num |
expression sequence number, or NULL |
append |
logical, should we add to the list of expressions to be skipped? |
skipcode
can be used to force certain expressions to be skipped
from evaluation when using the runcode
function (for example, if
certain external resources are not available). There is a globally
maintained list of expressions that will be skipped for a given source
file.
If num
is NULL
, then the list of skipped expressions is
cleared.
Nothing useful is returned; the global list of expressions to be skipped is modified.
