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.
