I found that FoldEnrichment,RichFactorand zScore are not in the ReactomePA::enrichPathway result. However, these fields are in the clusterProfiler::enrichKEGG and clusterProfiler::enrichGO. Considering that all of these three functions use DOSE::enricher_internal to perform enrichment analysis and there is an update for adding the above mentioned fields, why ReactomePA::enrichPathway result dose not have these three columns?

library(ReactomePA)
data(geneList, package="DOSE")
de <- names(geneList)[abs(geneList) > 1.5]
x <- enrichPathway(gene=de, pvalueCutoff = 0.05, readable=TRUE)
colnames(x@result)
> colnames(x@result)
[1] "ID"          "Description" "GeneRatio"   "BgRatio"     "pvalue"      "p.adjust"   
[7] "qvalue"      "geneID"      "Count"

library(clusterProfiler)
gene <- names(geneList)[abs(geneList) > 2]
kk <- enrichKEGG(gene         = gene,
                 organism     = 'hsa',
                 pvalueCutoff = 0.05)
colnames(kk@result)
> colnames(kk@result)
 [1] "category"       "subcategory"    "ID"             "Description"    "GeneRatio"     
 [6] "BgRatio"        "RichFactor"     "FoldEnrichment" "zScore"         "pvalue"        
[11] "p.adjust"       "qvalue"         "geneID"         "Count"

Re-install ReactomePA should ensure it works.
