The column types from Raven DataFrames are mapped to the corresponding R types. More specifically, all integer types (byte, short, int, long) are mapped to the R 'integer' type. The floating point types (float, double) are mapped to the R 'double' type. Both string and char types are mapped to the R 'character' type. Booleans are mapped to the R 'logical' type. Binary columns are represented as R 'list' types containing raw vectors.
A data.frame object

for deserializing vectors
of raw bytes.
