Return a subset of a ctd object.
Usage
# S4 method for class 'ctd'
subset(x, subset, ...)Arguments
- x
a ctd object.
- subset
An expression indicating how to subset
x.- ...
optional arguments, of which only the first is examined. The only possibility is that this argument be named
indices. See “Details”.
Value
A ctd object.
Details
This function is used to subset data within
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).
