In armgong/rjulia2: Integrating R and Julia -- Calling Julia from R

Description

julia_LoadDataArrayFrame() loads the DataArray and DataFrames julia packages, and julia_DataArrayFrameInited() checks if they have been loaded and work.

jloaddf is identical to julia_LoadDataArrayFrame, and jdfinited is identical to julia_DataArrayFrameInited, just short forms for convenience.

Usage

julia_LoadDataArrayFrame()
jloaddf()

julia_DataArrayFrameInited()
jdfinited()

Value

julia_DataArrayFrameInited() (and hence jdfinited()) return a logical, TRUE if the julia packages are there.

Examples

julia_DataArrayFrameInited() # TRUE or FALSE in any case

if(julia_DataArrayFrameInited())
   julia_LoadDataArrayFrame()
## ^^^^^^^^^^^^^^^^^^^^^^^^^^  fails if  not installed in Julia
