prophet_plot_components() error in rowSums(df[, holiday.comps]) : 'x' must be numeric about prophet

[bletham]

The following steps should recreate the issue:

holiday.comps <- unique(m$holidays$holiday)
s <- rowSums(fcst[, holiday.comps])

Does it?
Can you paste the output of str(fcst)? It seems one of the columns must have gotten non-numeric data in it somehow.

I'm experiencing the same issue, but all my columns are numeric, and all the holiday dates are unique.

My code was working until I simply unified all holidays under a single label ("campaign", since they were all a special kind of past and future campaigns). Given the error thrown and this line from the rowSums help file...

an array of two or more dimensions, containing numeric, complex, integer or logical values, or a numeric data frame.

...it seems like the code isn't set up to handle less than two values of "holiday" (in which case you would simply be passing a vector to rowSums -- thus the error).

[rschoenbeck]

Ah, and it also seems that holiday.comps would occasionally come out as a factor (thus interpreted by R as a numeric position index).

@rilut if you install from Github to get the fix in #39 does it work for you?

@bletham Yes, just installed prophet from github and #39 solved my issue 😄
