> {{glue}} package is quite natural for sending parameterized queries to Spark from R. Very similar to Python's {{format}} for strings. Error is as simple as
> {code:java}
> library(glue)
> library(sparkR)
> sparkR.session()
> query = glue_data(list(val = 4), 'select {val}')
> sql(query){code}
> Error in writeType(con, serdeType) : 
>   Unsupported type for serialization glue
> {{sql(as.character(query))}} works as expected but this is a bit awkward / post-hoc
