I am having the same issue as in this thread:Unable to see collections in mongo DB when connected through R
I am successfully connected to mongoDB.
&
rmongodb is no longer supported and removed from CRAN
Reference: https://github.com/dselivanov/rmongodb
This function is working correctly for me in v1.8.0:
mongo <- mongo.create()
mongo.is.connected(mongo)
# [1] TRUE
db <- "test"
mongo.get.database.collections(mongo, db = db)
[1] "test.test"
