Examples

data(power_example)
# Fit the local power surface of avg_log2FC_abs between 1 and 2
avg_log2FC_abs_1_2<-dplyr::filter(power_example,avg_log2FC_abs>1 & avg_log2FC_abs<2)
# Fit the model
bst<-fit_XGBoost(power_example$power,avg_log2FC=power_example$avg_log2FC_abs,
avg_PCT=power_example$mean_pct,replicates=power_example$sample_size)
pred<-pred_XGBoost(bst,n.grid=30,xlim=c(0,1.5),ylim=c(0,0.1),replicates=3)
