Проверка функции plotPRD

1. Неправильный формат исходных данных (нужен фрейм данных):

df <- c(1, 2, 3, 4, 5) # Vector
plotPRD(df)

Error in plotPRD(df) : 
  Check the format of the input data. The input data needed in the form of
           a data frame containing columns named 'actual', 'forecast', and 'method'.

2. Правильный формат исходных данных, но названия столбцов не совпадают (нужны “actual”, “method” и “forecast”)

df1 <- read.csv("D:/01_Projects/FORA/FORA/df_forecast.csv", header=FALSE)
plotPRD(df1)

Error in plotPRD(df1) : Check column names

3. Правильные исходные данные:

df1 <- read.csv("D:/01_Projects/FORA/FORA/df_forecast.csv", header=TRUE)
plotPRD(df1)
