Getting Eclipse/Scala-IDE set up for the Coursera Scala class was a pain. This is because the course materials were created for Scala 2.10, but the editor and IDE are set up with 2.11. Plus lots of other versions, dependencies, etc. have changed.

So here's what I needed to do for the example assignment:

Do this:
- However, I did not comment out the Eclipse plugin line in project/buildSettings.sbt. Instead, I changed it to version 2.2.0, which worked. (I think 2.1.0 is deprecated and no longer hosted.)
After this, sbt built (command sbt eclipse) and the package imported in Eclipse, but I had errors, and my Scala tests wouldn't run.
Finally, I needed to right click the project and do Properties -> Scala Compiler -> Scala Installation and choose 2.10. I got this tip from here

	select count(*), var, unit, sum(start - stop)
	from (
	select movie, montime, mofftime
	from (spikes, showings
	where spikes.time > ontime and spikes.time < offtime)
	join etho on movie )
	group by etho.var, unit

	ddir <- '~/data/bartc' # data directory
	load(file=paste(ddir, 'fitdata', sep='/'))

	extractfun <- function(x) {
	outs <- c(x$baseline, x$effects)
	names(outs)[1] = 'baseline'
	return (outs)
	}

	dat <- as.data.frame(t(sapply(fitobjs, FUN=extractfun, simplify=TRUE)))

	srand(12345)

	function makeLtri(x)
	l = length(x)
	p = round(Int, (sqrt(1 + 8l) - 1) / 2)
	L = zeros(eltype(x), (p, p))
	k = 1
	for j in 1:p
	for i in j:p
	L[i, j] = x[k]

	from psychopy import core, visual
	from psychopy.visual.circle import Circle

	class Flicker(Circle):
	"""
	Creates a flickering circle in the upper right corner of the screen.
	This is to be used as a timing marker by a photodiode.
	The presence or absence of the circle marks out an 8-bit binary pattern,
	flanked at the beginning and end by a 1 (e.g., 5 is 1000001011).
