Upload R data to SciDB
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
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.
