cas.readRDS: Read an RDS File and Upload to a CAS Table

In sassoftware/R-swat: SAS Scripting Wrapper for Analytics Transfer (SWAT)

Read an RDS File and Upload to a CAS Table

Description

This function is a convenience wrapper for the R readRDS and as.casTable functions. After reading the file that is accessible to the R client, it is uploaded to an in-memory table in CAS (the server).

Usage

cas.readRDS(
  conn,
  file,
  refhook = NULL,
  casOut = list(name = "", replace = FALSE)
)

Arguments

conn	An instance of a CAS object that represents a connection and CAS session.
file	An character string that specifies the filename for the RDS file. This value is passed to readRDS.
refhook	An optional value that is passed to readRDS.
casOut	An optional character or list. If you specify a string, then the string is used as the in-memory table name. A list can be used to specify properties for the in-memory table as follows: name An optional character that specifies the name for the in-memory table. By default, the name of the data frame is used. caslib An optional character that specifies the caslib. Specify this parameter to override the active caslib. label An optional character that specifies a descriptive label for the data. replace An optional logical. When set to TRUE, you can replace an existing in-memory table with the same name in the same caslib. The default value is FALSE. promote An optional logical. When set to TRUE, the in-memory table has global scope and can be available to other CAS sessions (subject to access controls). The default value is FALSE and the in-memory table has session scope so that it is accessible with the session that uploaded the table only. Session-scope tables are ideal for data analysis. Global-scope tables are better suited for reporting. replication An optional numeric that specifies the number of redundant copies of in-memory blocks. This parameter applies to distributed servers only. The default value is 1.

Value

CASTable
