Hello, I have a vector like this:
> head(geneSymbol) Ku8QhfS0n_hIOABXuE Bx496XsFXiAlj.Eaeo W38p0ogk.wIBVRXllY QIBkqIS9LR5DfTlTS8 BZKiEvS0eQ305U0v34 6TheVd.HiE1UF3lX6g "MACC1" "GGACT" "A4GALT" "NPSR1-AS1" "NPSR1-AS1" "AAAS" it has around 15000 entries. How do I replace all values with NA expect these that are named like this: geneSymbol[c("0lQ1XozriVZTn.PezY","uaeFiCdegrnWFijF_s","ZOluqaxSe3ndekoNng","912ny6eCHjnlY2XSCU","odF3XHR8CVl4SAUaUQ")] > geneSymbol[c("0lQ1XozriVZTn.PezY","uaeFiCdegrnWFijF_s","ZOluqaxSe3ndekoNng","912ny6eCHjnlY2XSCU","odF3XHR8CVl4SAUaUQ")] 0lQ1XozriVZTn.PezY uaeFiCdegrnWFijF_s ZOluqaxSe3ndekoNng 912ny6eCHjnlY2XSCU odF3XHR8CVl4SAUaUQ "FLCN" "FLCN" "FLCN" "UCA1" "IL1B" Thanks Ana ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
