so errorEst works, but only takes the max coverage now which gives minimum error. need to calculate with each proxy configuration, so a direct link with ENSORecon is probs the easiest.
errorEstimate works; creates .csv file RMSE with annual and 30-yr (set at top of script) RMSEs. now to add this to correlation graphic...
proxyENSOcor now takes in error, plots nicely with ggplot2. finish up obs.per.time bit, probs combine using multiplot?
