dbWriteTable error message

I am at loss of what is going on here ...

I am trying to write to a SQLite database:

con <- dbConnect(dbDriver("SQLite"), dbname="pres-docs.rqda")

I have a data frame that is 889 rows by 7 columns.  The column number
and types agree with the database table columns and column type.

dbWriteTable(con, "fileAttr", DF.4, row.names=FALSE, overwrite=TRUE)

Then I get the following error:

[1] FALSE
Warning message:
In value[[3L]](cond) :
  RAW() can only be applied to a 'raw', not a 'character'

Where could I start looking?

Thanks,
Henri-Paul
