Examples

# Recency-aware augmentation over sliding windows
# Load package and example dataset
library(daltoolbox)
data(tsd)

# Convert to 10-lag sliding windows and preview
xw <- ts_data(tsd$y, 10)
ts_head(xw)

# Apply awareness augmentation (bias toward recent rows)
augment <- ts_aug_awareness()
augment <- fit(augment, xw)
xa <- transform(augment, xw)
ts_head(xa)
