gains_graph: Create Scatterplot of Investment Gains

In stocks: Stock Market Analysis

Description

Creates scatterplot of gains (daily or otherwise) for one or more investments vs. another.

Usage

gains.graph(tickers = NULL, ...,
            gains = NULL,
            prices = NULL,
            orders = 1,
            add.plot = FALSE,
            colors = NULL,
            plot.list = NULL,
            points.list = NULL,
            legend.list = NULL,
            pdf.list = NULL,
            bmp.list = NULL,
            jpeg.list = NULL,
            png.list = NULL,
            tiff.list = NULL)

Arguments

tickers	Character vector of ticker symbols. Gains for the first ticker are plotted on the x-axis, and gains for all other tickers are plotted on the y-axis.
...	Arguments to pass along with tickers to load.gains function, if you wish to load data on the fly rather than specify gains or prices.
gains	Numeric matrix of gains (daily or otherwise), where each column has gains for a particular investment. Gains from the first column are plotted on the x-axis, and gains for all other columns are plotted on the y-axis.
prices	Numeric matrix of prices (daily or otherwise), where each column has prices for a particular investment. Gains derived from the first column are plotted on the x-axis, and gains derived from all other columns are plotted on the y-axis.
orders	Numeric value or vector of values specifying the order of linear regression models for each y-axis fund. Set to 1 for simple linear regression, 2 for linear regression with first-order and second-order terms, and so on.
add.plot	If TRUE, data is plotted on current plot frame rather than a new one.
colors	Character string of colors for each y-axis investment.
plot.list	Optional list of inputs to pass to plot function.
points.list	Optional list of inputs to pass to points function.
legend.list	Optional list of inputs to pass to legend function.
pdf.list	Optional list of inputs to pass to pdf function. If not NULL, .pdf file is created.
bmp.list	Optional list of inputs to pass to bmp function. If not NULL, .bmp file is created.
jpeg.list	Optional list of inputs to pass to jpeg function. If not NULL, .jpg file is created.
png.list	Optional list of inputs to pass to png function. If not NULL, .png file is created.
tiff.list	Optional list of inputs to pass to tiff function. If not NULL, .tif file is created.

Details

If tickers input is specified, it gets passed to load.gains to load historical prices from Yahoo! Finance using the quantmod package [1]. If gains or prices is specified, the graph is based directly on that information. Either way, the first fund's gains are plotted on the x-axis, and all the others are plotted on the y-axis.

Value

In addition to the graph, a list containing fitted linear regression models returned by the lm function for each y-axis fund vs. the x-axis fund.
