getMainProbes: Remove control probesets from ST arrays
Description
This function is designed to remove all but the 'main' type of probesets
from the Gene ST array types.
Usage
getMainProbes(input)
Arguments
input
Either a character string (e.g., "pd.hugene.1.0.st.v1") or a
FeatureSet object.
Value
If the argument is a character string, returns a data.frame
containing probeset IDs along with the probeset type, that can be used to
subset e.g., an ExpressionSet of Gene ST data, or an MArrayLM object created
from Gene ST data. Note that the order of the probesets is not guaranteed to
match the order in your ExpressionSet or MArrayLM object, so that should be
checked first. If the argument is a FeatureSet object, it returns a
FeatureSet object with only main probes remaining.
