x |
an object. |
An integer giving the length of the object. See the “Methods” section below for details.
signature(x = "SampleSetup")
get the number of set up samples.
signature(x = "VirtualContControl")
get the number of contamination levels to be used.
signature(x = "VirtualNAControl")
get the number of missing
value rates to be used (the length in case of a vector in slot
NArate
or the number of rows in case of a matrix).
signature(x = "VirtualSampleControl")
get the number of samples to be set up.
