Arguments

x

an MDB object

path

the path where the MDB should be written

readParameters

The following parameters are currently supported:

• delim: a single character used to separate fields within a record (default: '\t')

• quoted_na: a single logical indicating if missing values inside quotes should be treated as missing values or strings. WARNING: THIS PARAMETER IS NOT TAKEN INTO ACCOUNT WITH readr>=2.0.0.

• na: String used for missing values. The default value for reading a fileMDB is "NA". But the default value for writing a fileMDB is ""<NA>"". This value is written in the DESCRIPTION.json file to avoid ambiguity when reading the fileMDB.

htmlModel

a logical. If TRUE (default) the model is also plotted in an html file.

compress

a logical specifying whether saving data is to use "gzip" compression (default: TRUE)

by

the size of the batch: number of records to write together (default: 10^5)

...

method specific parameters

Value

A fileMDB object.
