[R] Prophet package

[Andras Farkas]

Dear All


wonder if you could assist with the following

we have:

library(prophet) 

library(dplyr) 


abc<-c(0.3684693,0.4938679, 0.4429201,0.452598,0.4301452,0.4315169, 
0.447026,0.496179,0.4045693,0.398533, 0.3551111,0.431079,0.4063136,0.4120126,0.5210375,0.402897,0.4466131,0.5005669,0.5014164,0.5042271,0.5498575,0.6014215,0.4415863,0.4377443,0.4316092,0.4156757,0.3517915,0.3669508,0.3899471,0.3964143,0.4001074,0.3851003,0.4222451,0.375324,0.3652045,0.3376978 
,0.383012,0.3763665,0.3550609,0.2958678,0.3726571,0.3442298 
#,0.3403275,0.2973978 
#, 0.4,0.4,0.4, 0.4,0.4,0.4, 0.4,0.4,0.4 

) 

df<-data.frame(ds = seq(as.Date('2013-08-01'), as.Date('2017-01-01'), by = 'm'),abc) 
names(df)<-c("ds","y") 


m<-prophet(df,yearly.seasonality = TRUE) 
future <- make_future_dataframe(m, periods = 730) 
forecast <- predict(m, future) 
plot(m, forecast)
points(x=as.Date('2017-02-01'),y=0.5)

results in error message :


Error in plot.xy(xy.coords(x, y), type = type, ...) : 
plot.new has not been called yet

would you have a solution to plot the point on the plot?

appreiate the help,
