[jamesbangbang1126]

library(Spectrum)
enrichmentNetwork(enrich@result,
clustMethod = as.character("spectral"),
drawEllipses = T,
fontSize = 2.5,
repelLabels = T
)

Error in as.character(package) :
cannot coerce type 'closure' to vector of type 'character'

Thank you in advance. How to fix this problem？
