What formula does Jamovi 2.4.5.0. use for Spearmans rho? Is there a correction for tied ranks?

jamovi uses the cor.test(..., method='spearman') from R to calculate spearman's rho.
if you go noodling through the docs from R, you should be able to find what you need.

Hi
seolmatrix module uses the following R package to compute spearman cor.
# compute spearman correlation with psych package--------
spear <- psych::corr.test(mydata, method="spearman")
Best
