[R] Automatic detachment of dependent packages

[Paul Smith]

Dear All,

When one loads certain packages, some other dependent packages are
loaded as well. Is there some way of detaching them automatically when
one detaches the first package loaded? For instance,

> library(sqldf)
Loading required package: RSQLite
Loading required package: DBI
Loading required package: gsubfn
Loading required package: proto

but

> detach(package:sqldf)
>
> search()
 [1] ".GlobalEnv"        "package:gsubfn"    "package:proto"
 [4] "package:RSQLite"   "package:DBI"       "package:stats"
 [7] "package:graphics"  "package:grDevices" "package:utils"
[10] "package:datasets"  "package:methods"   "Autoloads"
[13] "package:base"

The packages

RSQLite
DBI
gsubfn
proto

were not detached.

Thanks in advance,

Paul
