RevoScaleR-defunct: Defunct functions in RevoScaleR

Description

The functions or variables listed here are no longer part of RevoScaleR as they are no longer needed.

Usage

                  
  rxGetVarInfoXdf(file, getValueLabels = TRUE, varsToKeep = NULL,
                  varsToDrop = NULL, computeInfo = FALSE) 
                  
  rxGetInfoXdf(file, getVarInfo = FALSE, getBlockSizes = FALSE,
               getValueLabels = NULL, varsToKeep = NULL, varsToDrop = NULL,
               startRow = 1, numRows = 0, computeInfo = FALSE, verbose = 0)                 
                  
 

Arguments

file

either an RxXdfData object or a character string specifying the .xdf file. If a local compute context is being used, this argument may also be a list of data sources, in which case the output will be returned in a named list. See the details section for more information.

getValueLabels

logical value. If TRUE, value labels (including factor levels) are included in the output if present.

getVarInfo

logical value. If TRUE, variable information is returned.

getBlockSizes

logical value. If TRUE, block sizes are returned in the output for an .xdf file, and when printed the first 10 block sizes are shown.

varsToKeep

character vector of variable names for which information is returned. If NULL, argument is ignored. Cannot be used with varsToDrop.

varsToDrop

character vector of variable names for which information is not returned. If NULL, argument is ignored. Cannot be used with varsToKeep.

startRow

starting row for retrieval of data if a data frame or .xdf file.

numRows

number of rows of data to retrieve if a data frame or .xdf file.

computeInfo

logical value. If TRUE, variable information (e.g., high/low values) for non-xdf data sources will be computed by reading through the data set.

verbose

integer value. If 0, no additional output is printed. If 1, additional summary information is printed for an .xdf file.

Details

rxGetVarInfo should be used instead of rxgetvarinfo. rxGetInfo should be used instead of rxGetInfoXdf.
