Supported types are “float32” and “numeric”, for bit floating point and bit floating point values, respectively. RevoScaleR makes it possible to analyze huge data sets easily xxf efficiently, and for most purposes the most efficient computations are done on a single. I didn’t know XDF’s worked like that?

Factors are variables that represent categories. For example, suppose we have some test scores for a set of male and female subjects.

We see that, in fact, fo number of rows per block varies from a low of to a high ofAs noted above, if you omit the outFile argument to rxDataStepthen the results will be returned in a data frame in memory. If explicitly set, the float data will then be converted to integer data when imported.
