I want to used a vector of values to search the rownames of a dataframe. I want the code to return a vector of row numbers associated with the rownames of interest. In the example below, if I provided c("GeneA","GeneC","GeneF") I would want c(1,3,6) returnd

The code I provide below reports a single rownumber from a single rowname. I haven't figured out a way to provide multiple searches and the search results I come up with only use a single search value.

which(rownames(df) == "GeneB")
[1] 2

We may use match

match(c("GeneA","GeneC","GeneF"), rownames(df))
