readCdfCellIndices(filename, units=NULL, stratifyBy=c("nothing", "pmmm", "pm", "mm"), verbose=0)character string specifying which and how
elements in group fields are returned.
If "nothing", elements are returned as is, i.e. as vectors.
If "pm"/"mm", only elements corresponding to
perfect-match (PM) / mismatch (MM) probes are returned (as vectors).
If "pmmm", elements are returned as a matrix where the
first row holds elements corresponding to PM probes and the second
corresponding to MM probes. Note that in this case, it is assumed
that there are equal number of PMs and MMs; if not, an error is
generated.
Moreover, the PMs and MMs may not even be paired, i.e. there is no
guarantee that the two elements in a column corresponds to a
PM-MM pair.integer specifying the verbose level. If 0, the
file is parsed quietly. The higher numbers, the more details.list where the names corresponds to the names
of the units read. Each unit element of the list is in turn a
list structure with one element groups which in turn
is a list. Each group element in groups is a list
with a single field named indices. Thus, the structure is
cdf
+- unit #1
| +- "groups"
| +- group #1
| | +- "indices"
| | group #2
| | +- "indices"
| .
| +- group #K
| +- "indices"
+- unit #2
.
+- unit #J
This is structure is compatible with what readCdfUnits() returns.Note that these indices are one-based.
