Change Excel Worksheet Tab Color

Question

I have added a worksheet to an excel spreadsheet using the following code using the xlsx package in R

library(xlsx)    
wb <- CreateWorkbook()
newsheet <- createSheet(wb, sheetName = 'Sheet1')

Is there a way to automatically change the color of the tab for "Sheet1"?

Answer 1

There is no reference to tabs in xlsx

My first instinct was to look look at XLConnect but there is no reference to tabs there either.
