Answer 1

You can simply write into a new sheet of an existing Excel file without modifiying the existing sheets or any other information by doing it this way:

library(xlsx)
a=1:10 
b=31:40
c=data.frame(a=a,b=b)

write.xlsx(c, "existing_Excel_file.xlsx", sheetName="New sheet name",  append=TRUE)

Remember to set the append argument of write.xlsx to TRUE and make sure the Excel file you are writing in to is in your current working Directory.
