How do I set the value of a specific cell using xlsx (R package)?

问题

I'm trying to set the value of a specific cell in xlsx. I'm doing this to add a title for the data frame that I added in Excel, but I can't figure it out. I tried createCells, createRows, getCells and getRows, but I can't seem to get any of them to work despite reading the documentation.

Without benefit of seeing your code and knowing exactly what you are trying to do, I suggest trying

setCellValue(cell, value)

For example, starting from scratch and creating a new excel file:

wb    <- createWorkbook(type="xlsx")           # create an empty workbook
sheet <- createSheet(wb, sheetName="Sheet1")   # create an empty sheet 
rows  <- createRow(sheet, rowIndex=1:10)       # 10 rows
cells <- createCell(rows, colIndex=1:6)        # 6 columns in each row
setCellValue(cells[[1,2]], "Data Frame Title Goes Here")   # put in Row 1, Column 2
