Examples
df <- data.frame(
year = 1900:1999,
value = 10 + 8*1900:1999 + runif(100L, 0, 100)
)
split_from_indices <- make_splits(
x = list(analysis = which(df$year <= 1980),
assessment = which(df$year > 1980)),
data = df
)
split_from_data_frame <- make_splits(
x = df[df$year <= 1980,],
assessment = df[df$year > 1980,]
)
