5076 Filter genes based on expression
Description
This function removes genes that are very lowly expressed.
Usage
filterGenes(spe, prop = 0.1)
## S4 method for signature 'SpatialExperiment'
filterGenes(spe, prop = 0.1)
## S4 method for signature 'Seurat'
filterGenes(spe, prop = 0.1)
Arguments
spe
|
a SpatialExperiment, Seurat, or SpatialFeatureExperiment object containing count data. |
prop
|
a numeric, indicating the proportion of loci/cells where the gene should be expressed (default is 0.1, i.e., genes should be expressed in at least 10% of the loci/cells). |
Value
a logical vector encoding which genes should be kept for further analysis.
