to consider it as an irregular time series, depending on what

Hi Markus,
My Java is a bit rusty, but I think when reading from an input stream
like the one you've set up, Java blocks if there's no input, waiting
until there is some to return. I don't think the stream ends until the
R process closes. You should test ready() to see if there is more

Maybe you should take this up with package maintainers (who may or may

Yes, but currently only alpha=0 and alpha=255 are supported by the
available devices that I know of (and I introduced this).
Adding alpha-level support is complicated for the devices people normally
