Error of the statistical methods when using the irGSEA.halfvlnplot function

[yecotoo]

Hi! I would like to know about what statistical methods are used when using the irGSEA.halfvlnplot function to draw? The violin diagram I drew with the geom_half_violin function is not the same as this method, here's my code, thanks!
ggplot()+
geom_half_violin(
data = df %>% filter(sample=="normal"),
aes(x = cell,y = value),colour=NA,fill="#197EC099",side = "l"
)+
geom_half_violin(
data = df %>% filter(sample=="tumor"),
aes(x = cell,y = value),colour=NA,fill="#FED43999",side = "r"
)+
mytheme+
theme_bw()+
ylab("Value")+xlab("Type")+
geom_point(data = df,aes(x=cell,y = value,fill=sample),
stat = 'summary',fun=mean,
position = position_dodge(width = 0.7))+
stat_summary(data = df,aes(x=cell,y = value,fill=sample),
fun.min = function(x){quantile(x)[2]},
fun.max = function(x){quantile(x)[4]},
geom = 'errorbar',color='black',
width=0.01,size=0.5,
position = position_dodge(width = 0.7))+
stat_compare_means(data = df,aes(x=cell,y = value,fill=sample),label = 'p.signif')
