deleted old versions of prep and EOF functions (outside 'functions' folder)
proxyMapping.R combines proxy info with EOFs to obtain weights and plot proxies over EOFs
weight by varexp or %*% EOF? going to try latter now
dot prod works as tested on CCSM historical. now adapt script to run for proxy data
need to know proxy locations first! continue with lon/latmatch scripting
something wrong with lon/latmatch now...
