Try using RDCOMClient or rcom:
library(RDCOMClient)
xl <- COMCreate("Excel.Application")
# next line optional
xl[["Visible"]] <- TRUE
wb <- xl[["Workbooks"]]$Open("/mydir/sample.xlsx")
sheet <- wb$Sheets("Sheet2")
xl[["DisplayAlerts"]] <- FALSE
sheet$Delete()
xl[["DisplayAlerts"]] <- TRUE
xl$Save()
xl$Quit()
