Fpp2 output to data frame

[mprozaki]

I am trying to export a forecast from the fpp2 package to xlsx. How can I tell if the output from the forecast is a table that can be exported?

write.xlsx(zfc33, file = "wfc33.xlsx", asTable = TRUE)
Error in write.xlsx(zfc33, file = "wfc33.xlsx", asTable = TRUE) :
x must be a data.frame is asTable == TRUE

Use as.data.frame() before writing, like this:

library(forecast)
library(openxlsx)
zfc33 <- USAccDeaths %>% ets() %>% forecast()
zfc33 %>%
  as.data.frame() %>%
  write.xlsx(file = "wfc33.xlsx", asTable = TRUE)

I will try this out - thank you for the help!

That worked great. Thank you. I am digging in and working with other features of the package now.
