Hi,

I viewed your presentation from useR2018 and was deeply impressed by what's possible with fasster. This looks really amazing!

I've been working my way through the examples of the README.

> fit <- tsibbledata::UKLungDeaths %>%
+   FASSTER(fdeaths ~ mdeaths)
> 
> class(fit)
[1] "mable"      "lst_ts"     "tbl_df"     "tbl"        "data.frame"
> 
> fit %>% summary
FASSTER Model:
 fdeaths ~ mdeaths 

Estimated variances:
 State noise variances (W):
  mdeaths
   1.7119e-34

 Observation noise variance (V):
  1.6631e+03

Everything up to this point works perfectly. But when I try

fit %>% components

or

fit %>% forecast(h=24) %>% autoplot

I get an error:

Error in .f(.x[[i]], ...) : object 'object' not found

Please let me know if you need more information.

Best regards, Andrew.

Hi, Thanks for letting me know. A recent change to tsibble has caused a few issues with fablelite that have been resolved here: https://github.com/tidyverts/fablelite/commit/bbd69751c3fa0937343ccd2dec836d9d2b493725

If you reinstall fablelite with 

devtools::install_github("tidyverts/fablelite")

It should now work.

Might I add, thanks for your kind comments!

For sure! This is going to be a massive game changer for a bunch of my analyses which I have been battling to do with other time series approaches.
