Have a long script that runs fine on windows (32 bit). When I try to run in
on two different macs (64 bit), however, it hangs with identical behavior.

I start with:

This results in messages:
Loading required package: DBI
Loading required package: RSQLite
Loading required package: RSQLite.extfuns
Loading required package: gsubfn
Loading required package: proto
Loading required package: chron

I then read some data, etc.

I execute the following:

#merge raw data and all possible combinations
  df.final <- sqldf('select Date, Hour, x as RoomsInUse from
    left join "df.aggregate" using (Hour, Date)')

I receive the messages:
Loading required package: tcltk
Loading Tcl/Tk interface ... 

Then I get into some kind of loop. Message at bottom ribbon says:


On the pc implementation it runs flawlessly, and quickly. 

Truly appreciate any ideas.
