44 goodSamplesGenesMS<br />

Details<br />

The constants ..minNSamples and ..minNGenes are both set to the value 4. For most data sets,<br />

the fraction of missing samples criterion will be much more stringent than the absolute number of<br />

missing samples criterion.<br />

Value<br />

A logical vector with one entry per gene that is TRUE if the gene is considered good and FALSE<br />

otherwise. Note that all genes excluded by useGenes are automatically assigned FALSE.<br />

goodSamplesGenesMS Iterative filtering of samples and genes with too many missing entries<br />

across multiple data sets<br />

Description<br />

This function checks data for missing entries and zero variance across multiple data sets and returns<br />

a list of samples and genes that pass criteria maximum number of missing values. If necessary, the<br />

filtering is iterated.<br />

Usage<br />

goodSamplesGenesMS(<br />

multiExpr,<br />

minFraction = 1/2,<br />

minNSamples = ..minNSamples,<br />

minNGenes = ..minNGenes,<br />

verbose = 2, indent = 0)<br />

Arguments<br />

multiExpr<br />

minFraction<br />

minNSamples<br />

minNGenes<br />

verbose<br />

indent<br />

expression data in the multi-set format (see checkSets). A vector of lists, one<br />

per set. Each set must contain a component data that contains the expression<br />

data, with rows corresponding to samples and columns to genes or probes.<br />

minimum fraction of non-missing samples for a gene to be considered good.<br />

minimum number of non-missing samples for a gene to be considered good.<br />

minimum number of good genes for the data set to be considered fit for analysis.<br />

If the actual number of good genes falls below this threshold, an error will be<br />

issued.<br />

integer level of verbosity. Zero means silent, higher values make the output<br />

progressively more and more verbose.<br />

indentation for diagnostic messages. Zero means no indentation, each unit adds<br />

two spaces.
