It seems that read.table() in R 3.0.1 (Linux 64-bit) does not consider
quoted integers as an acceptable value for columns for which
colClasses=integer. But when colClasses is omitted, these columns are
read as integer anyway.
For example, let's consider a file
I agree that quoted integer columns are not the most efficient way of
delivering csv-files. However, the sad reality is that one receives such
formats and still needs to read the data. Therefore it is not helpful to
state that one should 'consider character to be the correct colClass

I think this is not the right approach -- quoting is a transport-layer
feature of the CSV format, not part of the application layer. Quotes
should always be interpreted away from column data before any data is
handed to the application layer. (CSV does not _have_ any application
layer; type
