Hello,
I am trying to forecast sales using an R script. The R script works fine in R Studio but returns an empty table when used in Power BI.
Here is my data:
Week | Unit |
1/3/2018 | 355263 |
1/10/2018 | 398547 |
1/17/2018 | 332485 |
... | ... |
"Week" is formatted as a date and "Unit" is formatted as a number.
I use the following code:
library(dplyr)
library(forecast)
library(lubridate)
salesTS <- ts(dataset$`Unit`, frequency = 52, start = 2018)
salesLog <- log(salesTS)
salesLogHW <- HoltWinters(salesLog)
nextYearSales <- forecast(salesLogHW, h=52)
"This table is empty" is displayed after I try to transform the dataset to time series.
Does anyone know how I can make my code work and obtain a forecast for 52 weeks ahead?
Thanks,
Alona
where are the week dates in your R script? (the "week" column)
