Replacement of missing values
Methods for replacement of missing values. Missing values should be indicated by NA in the expression matrix.
object of the class ExpressionSet.
method for replacement of missing values:
Number of neighbours, if one of the knn method for
replacement is chosen (
The function produces an object of the ExpressionSet class with missing values replaced.
The replacement methods knn and knnw can computationally intensive for large gene expression data sets. It may be a good idea to run these methods as a ‘lunchtime’ or ‘overnight’ job.
