As the probes are spotted onto the in quaduplet or duplicate the values have to be combined in some way. This function takes the median of the intensities for the spots. Effectively the mean for duplicates. If less than half of the spots are present an NA is added

1 | ```
summarizeIntensitiesAsMedian(eset,minSumlength=0, madAdjust=FALSE)
``` |

`eset` |
ExpressionSet containing probe intensity data to be summarized |

`minSumlength` |
The lowest acceptable length of the matrix to calculate a median |

`madAdjust` |
if |

1 2 3 4 5 | ```
#Calculate the median of a matrix omiting NAs
## Not run:
summarizeIntensitiesAsMedian(eset,minSumlength=0,madAdjust=TRUE)
## End(Not run)
``` |
