In both cases, row and column names are quoted if they are written. Date in a transforms argument. Supported types are “float32” and “numeric”, for bit floating point and bit floating point values, respectively.


The advantage of this, over the other answer, is that it reads only those convwrt columns into memory.

Note for “factor” and “ordered” type, the levels will be coded in the order encountered. Four additional variables providing information on the RevoScaleR processing are available for use in your comvert functions:. We specify the variables needed to process the transformation in the transformVars argument. By default, rxImport loads data into an in-memory data frame, but by specifying the outFile parameter, rxImport creates an XDF file. If TRUEthe factor levels will be coded in the order encountered.

If you have variables that are already factors, you may want change the order of the levels, the names xcf the levels, or how they are grouped. The integers 1 through 9 specify increasing levels of compression, where higher numbers perform more compression, but take more time. For instructions, see Import text data.
