An expression indicating how to subset |

This function is used to subset data within the
levels of a ctd object. There are two ways of working. If
subset
is supplied, then it is a logical expression
that is evaluated within the environment of the data
slot of the object (see Example 1). Alternatively, if the
...
list contains an expression defining indices
,
then that expression is used to subset each item within the
data
slot (see Example 2).
A ctd-class
object.
