Hello All,

Just wanted to report a bug, or at least unexpected behavior. I am new to monetdb, and could not submit this to your bugzilla tracker.

*Background* I successfully have used MonetDB with Docker ( https://www.monetdb.org/blog/docker-container-monetdb-r) and was able to create FUNCTIONs and AGGREGATEs with R (as described here: https://www.monetdb.org/content/embedded-r-monetdb). This blog post also states:

"As a final note on usage, you can use any R package from CRAN within your function without explicitly installing it. We overloaded the library function in R to automatically install missing packages."

*Description* However, I am not able to use external R packages available from CRAN. The session below describes both Docker commands and SQL used. This session was run on OSX using Docker Machine.

Thank you, -Cas
