Description

Compute and Plot a correlation diagram between selected sotcks, or between stocks and a (single) market index. After computing the correlations a statistical test shows only the significant correlations. The non-significant ones are crossed

Usage

stock.correlation(ticker, from, to, market_index = NULL)

Arguments

from	A single character variable storing the starting date from which we want to download the data. The format should be "yyyy-mm-dd"
to	A single character variable storing the ending date from which we want to download the data. The format should be "yyyy-mm-dd"
