filter.NA: Filtering of genes based on number of non-available...
In Mfuzz: Soft clustering of time series gene expression data

Description Usage Arguments Value Author(s) Examples

This function can be used to exclude genes with a large number of expression values not available.

1	filter.NA(eset,thres=0.25)

`eset`	object of the class “ExpressionSet”.
`thres`	threshold for excluding genes. If the percentage of missing values (indicated by NA in the expression matrix) is larger than `thres`, the corresponding gene will be excluded.

The function produces an object of the ExpressionSet class. It is the same as the input eset object, except for the genes excluded.
