The array annotations are chip-specific so you need to choose theĪnd provide commented, minimal, self-contained, reproducible code. Install the package, load it, then typeĪnd look at the help files for each topic for more details and examples. U133 plus 2 chip and you can use to map affy probe IDs to gene Other packages for connecting gene identifiers to (for example) geneįor example, the package hgu133plus2.db contains annotations for the Yes, Bioconductor has annotation packages for microarray chips plus > link to some worked example would be appreciated. > I am looking at bioconductor, but till now could not find a solution. Is there any package in R which facilitates this? > microarray probe, gene, pathway, gene ontology, and homology for a set of A targeted DNA microarray runs from 10 to 100 per sample, says Schena, whereas the whole human genome is typically 100 to 1,000 per sample. > I have clustered microarray gene expression data and trying to map between > myAnnot ID Symbol tmp tmp fData(eset.norm) wrote: If hgu133 plus 2.0 is your chip something like the following could be employed You could use the s apply function to create a data frame of the annotation.
