In Paradigm4/SciDBR: An R Interface to SciDB

Upload R data to SciDB

Description

Upload R data to SciDB

Usage

as.scidb(db, x, name, start = NULL, gc = NULL, ...)

Arguments

db	a scidb database connection returned from scidbconnect
x	an R data frame, raw value, Matrix, matrix, or vector object
name	a SciDB array name to use
start	starting SciDB integer coordinate index (does not apply to data frames)
gc	set to FALSE to disconnect the SciDB array from R's garbage collector
...	other options, see .df2scidb.shim: for uploading R data frame .matrix2scidb.shim: for uploading sparse matrices .matvec2scidb.shim: for uploading dense R vectors, arrays or matrices .raw2scidb.shim: for uploading raw values

Value

A scidb object

Note

Supported R objects include data frames, scalars, vectors, dense matrices, and double-precision sparse matrices of class CsparseMatrix. Supported R scalar types and their resulting SciDB types are:

• integer -> int32

• logical -> int32

• character -> string

• double -> double

• integer64 -> int64

• raw -> binary

• Date -> datetime

R factor values are converted to their corresponding character levels.
