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.
