Hi everyone I dont really have problems running fgsea itself but im trying to understand what gseaparam argument in fgsea() means. The vignette says it's a GSEA weight parameter. but weightage of what? each fgsea term? and to what exactly

hope to hear some clarifications; tried googling it's still not clear to me.

This is the power, to which all input gene-level stats are raised to. If gseaParam is zero, then all gene-level stats effectively become ones and GSEA test becomes Kolmogorov-Smirnov test. The default value of gseaParam is one, meaning that gene-level stats are used as is.
