Today I tried to retrieve results for a query using the queryDGIdb function that yielded results just fine a few months back. The function is returning only empty data frames now. In fact not even the tutorial example will currently yield results:

> library(rDGIdb)
> genes <- c("TNF", "AP1", "AP2", "XYZA")
> result <- queryDGIdb(genes)
> resultSummary(result)

Object of class "data.frame"
data frame with 0 columns and 0 rows

> sessionInfo( )
