openxlsxの使い方（自分が使うところだけ）
require(openxlsx)
tmpdat<- read.xlsx("./data.xlsx", sheet = 2, startRow = 9, detectDates=TRUE)
head(tmpdat)
wb <- createWorkbook()
addWorksheet(wb, 'Sheet1')
addWorksheet(wb, 'Sheet2')
writeData(wb, sheet = 'Sheet1', x = lm.res1, withFilter=F)
writeData(wb, sheet = 'Sheet2', x = lm.res2, withFilter=F)
saveWorkbook(wb, "lm.res.xlsx", overwrite = T)
