Issue with motif analysis using JASPAR

[yojetsharma]

I am not sure how to go ahead with the analysis. Can someone please help?

> pfm <- getMatrixSet(
+     x = JASPAR2020,
+     opts = list(collection = "CORE", tax_group = 'vertebrates', all_versions = FALSE)
+ )
> df_pfm <- data.frame(t(sapply(pfm, function(x)
+     c(id=x@ID, name=x@name, symbol=ifelse(!is.null(x@tags$symbol),x@tags$symbol,NA)))))
