Writing to Excel files comes up rather often, especially if you’re collaborating with non-OSS users. There are several options, but I like the xlsx package way of doing things. Authors use Java to write to Excel files, which are basically compressed XML files.

Alright, let’s get cracking.

First, let’s create some data.

sample.dataframe

If you don’t have the file created yet, you can just write the data into a new file.

library(xlsx) #load the package
write.xlsx(x = sample.dataframe, file = "test.excelfile.xlsx",
        sheetName = "TestSheet", row.names = FALSE)

If you already have a file created, you can add data to a new sheet, or just add it to the existing one. Here’s how you would add a data.frame to columns D and E (result not shown).

workbook.sheets workbook.test addDataFrame(x = sample.dataframe, sheet = workbook.test,
   row.names = FALSE, startColumn = 4) # write data to sheet starting on line 1, column 4
saveWorkbook(workbook.sheets, "test.excelfile.xlsx") # and of course you need to save it.

You can now open the file in your WYSIWYG editor.
