mergeProbesForGenes {GiANT} | R Documentation |
Merge multiple probes for one gene
Description
Merges all probes belonging to the same gene by identifying duplicate row names in a data matrix.
Usage
mergeProbesForGenes(dat,
method = c("mean", "max", "min", "median"))
Arguments
dat |
A numeric matrix of gene expression values for all analyzed genes. Here, each row corresponds to one probe, and each column corresponds to one sample. The rows must be named with the gene names and may contain duplicates if multiple probes correspond to the same gene. |
method |
The method which should be used to merge probes entries in |
Value
A matrix of the same structure as dat
, but possibly with fewer rows if probes were merged.

Examples
dat <- matrix(1:6, nrow=3, ncol=2)
rownames(dat) <- c("g1", "g2", "g1")
newDat <- mergeProbesForGenes(dat, method = "mean")
