Error in R about prophet

[seanjtaylor]

Thanks for the report! Can you let me know what version of Windows and R you're using. And also verify that you've installed RTools?

I use R version 3.3.2 (2016-10-31) and windows 10 pro 32bit. I installed RTools and I created prophet model.
Now I have another error -"Error in UseMethod("predict") : no applicable method for 'predict' applied to an object of class "character"". My code :
df0=data.frame(ds=(seq.Date(make_date(2017,01,01),make_date(2017,02,01),by = 1)),y = c(1:32))
pr0 =prophet(df0)
make_future_dataframe(pr0,periods = 10)
future0=make_future_dataframe(pr0,periods = 10)
forecast0 <- predict(pr0, future0)

[seanjtaylor]

Hmm this does not replicate for me, can you give me the output of

> class(prr0)
> pr0

Just to see what class was returned?

[marishadorosh]

I think it is a model of prophet.
class(pr0) returned: "list" "prophet"
And pr0 returned list of list ($growth, $changepoints and etc.)

Does
forecast0 <- prophet:::predict.prophet(pr0, future0)
work?

[marishadorosh]

Yes, it works! thank you

[seanjtaylor]

@bletham is this an S3 object issue?

[bletham]

@seanjtaylor I'm not sure exactly sure what could have happened here.

@marishadorosh can you paste the output of

library(prophet)
methods(predict)

And could you try restarting R and see if the issue persists? (a lame suggestion I know).

Fix confirmed in #94, but post if you have further issues with this!
