Loading a DataFrame from a file

Create and return a DataFrame from the content of the named file in the project. The file must be a CSV file, and the first data row will always be read as the header row.

Scala syntax

loadDataFrameOptionFromFile(pc: ProjectContext, filename: String): Option[DataFrame]
        // Get the resulting Option[DataFrame]
        val odf1 = ProjectUtil.loadDataFrameOptionFromFile
        if (odf.isDefined) {
             val df1 = odf1.get
             // do something with the DataFrame
        }

Python syntax

load_dataframe_from_file(pc, filenameOrFileData)
	# Call can return None

R syntax

loadDataFrameFromFile(pc, fileName)
	# Call can return NULL
