## S3 method for class 'AffymetrixCdfFile': isPm(this, units=NULL, force=FALSE, cache=TRUE, ..., verbose=FALSE)
units |
The units to be read. If NULL , all units are read. |
... |
Additional arguments passed to readCdfUnits . |
force |
If TRUE , cached results are ignored. |

Returns a logical
vector
of length K, where K equals the total number
of cells in the requested units. Note that the cells are ordered as
they occur in the units, that is, not in incremental order.
This method caches a logical
vector
of length N, when N equals the
number of cells on the array. The size of this vector is approximately
4*N bytes. The vector indicates if a cell is a PM or not.
