Description |
Reads the contents of a file or URL and creates an Table object with its values. If a file is specified, it must be located in the sketch's "data" folder. The filename parameter can also be a URL to a file found online. By default, the file is assumed to be comma-separated (in CSV format). To use tab-separated data, include "tsv" in the options parameter. If the file contains a header row, include "header" in the options parameter. If the file does not have a header row, then simply omit the "header" option. When specifying both a header and the file type, separate the options with commas, as in: loadTable("data.csv", "header, tsv") All files loaded and saved by the Processing API use UTF-8 encoding. |
