I get a corrupted file when I use Openxlsx

问题

I am using openxlsx to Write to existing xlsx file without altering the formatting.

my file is "razii.xlsx. I have done the following tasks:

library(openxlsx)
df1<-read.xlsx("C:/data/razii.xlsx",startRow = 3)

Next, I have analysed two columns using 'razii.xlsx' using R codes and I called it df2.

Now I want to write to the existing xlsx file without altering the formatting. I have used the following codes:

 wb <- loadWorkbook(file = "C:/data/razii.xlsx")
  addWorksheet(wb, "Razii")
 x <- df2
  writeData(wb, "Razii", x,  startRow = 3, rowNames = TRUE)
  saveWorkbook(wb, "C:/data/writeDatarazii.xlsx", overwrite = TRUE)

However, I get a corrupted file. Have I missed anything?
