R Error in as.vector(x, “character”) when using openxlsx to write excel

Question

I want to export the several dataframes into different sheets in one excel and my code is as follows:

aa<-data.frame(1:5,2:6)
ab<-data.frame(2:6,3:7)

wb <- createWorkbook()

sheet1 <- createSheet(wb, "Sheet1")
addDataFrame(aa,sheet1)

sheet2 <- createSheet(wb, "Sheet2")
addDataFrame(ab,sheet2)

saveWorkbook(wb,file="D:/aa.xlsx")

And then the Rstudio reports that:

Error in as.vector(x, "character") : cannot coerce type 'environment' to vector of type 'character'

Any thoughts would be helpful. Thanks.

Answer 1

aa<-data.frame(1:5,2:6) 
ab<-data.frame(2:6,3:7)

wb <- openxlsx::createWorkbook()
openxlsx::addWorksheet(wb, 'Sheet1')
openxlsx::writeData(wb, 'Sheet1', aa)

openxlsx::addWorksheet(wb, 'Sheet2')
openxlsx::writeData(wb, 'Sheet2', ab)

openxlsx::saveWorkbook(wb,file="D:/aa.xlsx")
