I am trying to do a micro-array analysis using CEL files for S. aures using R.
- I have used the following libraries:
source("https://bioconductor.org/biocLite.R") library("affy") library("limma") library("genefilter")
- Then I loaded the pd.s.aureus data set using the above and included it using the
- Then using the RMA method I imported the data to eset variable. After that I tried to do a non-specific filtering using nsFilter
esetF <- nsFilter(eset, remove.dupEntrez = FALSE, var.cutoff = 0.5)
Once I do that it gives me the error
Error: getAnnMap: package saureus not available
But I have loaded the "pd.s.aureus" library as there is no annotation data set in the name of saureus. (https://bioconductor.org/packages/3.7/data/annotation/)
Is there anything I am missing here ? Is there a way around this?
Thank you very much and any suggestion is much appreciated
