How do I append data from a data frame in R to an Excel sheet that already exists

Question

I have created dozens of data frames in R and would like to append them all to one sheet in an Excel file.

Here are two of the pages I have looked at in an attempt

Answer 1

To get around the original error that you mentioned:

Error in sheet$getWorkbook : $ operator is invalid for atomic vectors

You can try this:

wb <- loadWorkbook("")
addDataFrame(df,getSheets(wb)$, startRow = 712)
saveWorkbook(wb, )
