Determine whether the supplied object is a valid multiData structure
Attempts to determine whether the supplied object is a valid multiData structure (see Details).
isMultiData(x, strict = TRUE)
x |
An object. |
strict |
Logical: should the structure of multiData be checked for "strict" compliance? |
A multiData structure is intended to store (the same type of) data for multiple, possibly independent,
realizations
(for example, expression data for several independent experiments). It is a list where
each component corresponds to an (independent) data set. Each component is in turn a list that can hold
various types of information but must have a data component. In a "strict" multiData structure, the
data components are required to each be a matrix or a data frame and have the same number of
columns. In a "loose" multiData structure, the data components can be anything (but for most
purposes should be of comparable type and content).
This function checks whether the supplied x is a multiData structure in the "strict" (when
strict = TRUE or "loose" strict = FALSE sense.
Logical: TRUE if the input x is a multiData structure, FALSE otherwise.
