I'm a fool; why did I write data=qnrc in qdata()?
write a helper function rescale() and apply it to qscatter() and qparallel()
change the scale name 'var' to 'sd'
roxygenize; it seems qtime() examples can pass R CMD check now
let's consider CranvasPlot() later
restore qsave()
cosmetic changes for record_selector()
roxygenize
dependency on R version so that R CMD check does not complain about data/
