## --------------------------------------------------------------------- ## A. SIMPLE EXAMPLE ## --------------------------------------------------------------------- library(drosophila2probe) probes <- DNAStringSet(drosophila2probe) ## Check metadata slot: empty metadata(probes) ## Get generated seqinfo table seqinfo(probes) ## Subsetting seqinfo table to 10 seqnames probes10 <- probes[1:10] seqinfo(probes10) <- seqinfo(probes)[as.character(1:10)] ## See result: 10 seqnames seqinfo(probes10)
