%description
The R implementation of TIGER. TIGER integrates random forest algorithm
into an innovative ensemble learning architecture. Benefiting from this
advanced architecture, TIGER is resilient to outliers, free from model
tuning and less likely to be affected by specific hyperparameters. TIGER
supports targeted and untargeted metabolomics data and is competent to
perform both intra- and inter-batch technical variation removal. TIGER can
also be used for cross-kit adjustment to ensure data obtained from
different analytical assays can be effectively combined and compared.
