How to use periodogram inside a foreach/dopar construct? #45

Hi!

Using rethomics for some time now. Great work! I have written a wrapper around the periodogram function which cleans/arranges data and then loops through subsequent time-segments, calculating a periodogram for each segment.

This can take some time, and therefore I am trying to parallelize the calculations. It works ...kind of. The problem is that var within the periodogram function can't be found once periodogram is inside a foreach/dopar loop. Passing FUN and getting it via get(fun) works strangely enough. I think (!) the problem is the way periodogram evaluates var?

Please see this stackoverflow post from me: https://stackoverflow.com/questions/79561941/pass-column-name-as-argument-to-periodogram-function-inside-foreach-loop
