Error with subset

I have a data.frame which I want to subset based on a list of certain IDs. I want to extract all the rows from this data.frame which have the same ID as my variable "genes". So far I have:

Final_Genes <- subset(Merged_Results,Merged_Results$Entrez.ID == genes, select = c(1:8))

but this produces an error,

Warning messages:

    1: In is.na(e1) | is.na(e2) :
      longer object length is not a multiple of shorter object length
    2: In `==.default`(Merged_Results$Entrez.ID, genes) :
      longer object length is not a multiple of shorter object length

Which to be honest I don't understand.

Just substitute == with %in% and it worked for me, even with the subset command.

Try

Final_Genes<-Merged_Results[Merged_Results$Entrez.ID==genes,1:8]

This assumes that "genes" is that same as a single Entrez.ID. If genes is acutally a vector of several "Entrez.ID"s you could replace the == with %in%
