Hi

The variable transfer of tables from org to R caused sometimes 'could
not find function "read.table"' errors (e.g. when the file was tangled
into a ./data directory which was loaded by the function
devtools::load_all("./")). This can easily be fixed by adding the package
name to the call in R, i.e. replacing =read.table()= with
=utils::read.table()= which is done in this patch.

In R the calls read.table and utils::read.table are interchangeable (the
second one is actually preferred) so no negative effects can be
expected.

Cheers,

Rainer

Subject: [PATCH] ob-R.el: Add package name to read.table call

* lisp/ob-R.el:
(ob-R-transfer-variable-table-with-header): Add package name to call
of R function read.table (now utils::read.table).  This clarifies the
call as well as avoids 'could not find function' error in R under
certain conditions.
