sPlot: Scatter Plot Time Series

In cmann3/econ311: Functions for Intermediate Macroeconomics at UNL

Description

splot plots two economic time series against each other, taking into consideration object attributes such as 'units' and 'title'. splot works best with data collecting functions, such as fred in the the recon package.

Usage

sPlot(x, y, by = NULL, data = NULL, title = NULL, xlab = NULL,
  ylab = NULL, time = NULL, ylim = NULL, xlim = NULL, type = "p",
  col = NULL, lwd = 1, lty = NULL, colAxes = NULL, pch = NULL,
  cex = 1, colBG = NULL, bg = colBG, colPlot = NULL, colGrid = NULL,
  theme = "std", reg = NULL, rlwd = lwd + 1, mar = c(4, 4, 2, 1),
  cex.lab = 1, cex.axis = 0.75, las = 0, leg = NULL)

Arguments

x	'xts' object to be plotted on the x-axis
y	'xts' object to be plotted on the y-axis
by	object of factors to be plotted. Only 'cycle' supported for now, which plots by the business cycle
data	data object containing x and x
title	character title of plot
xlab	character label of x-axis
ylab	character label of y-axis
time	time period to restrict plot. Uses 'xts' convention, e.g., '1970-01/1972-06-03'.
ylim	numeric vector of limits on the y-axis
xlim	Date vector of limits on the x-axis
type	'p' for points, 'l' for lines, 'b' for both
col	character vector of color names to use for lines and points
lwd	line width
lty	line type. examples: 'solid', 'dotted', 'dashed'
colAxes	color of plot axes
pch	type of point to use
cex	size of objects in plot
colBG	background color
bg	background color of points
colPlot	color of plot background
colGrid	color of grids
theme	graphical theme of the plot. Only 'std' is supported.
reg	logical or character. Should a regression line by printed? If 'by', then a regression for each category.
rlwd	regression line width
mar	inner margins outside of plot. c(bottom,left,top,right)
cex.lab	size of labels
cex.axis	size of axis
las	tick label orientation on axis
leg	vector of character names to use in the legend. 'auto' uses object attributes

Value

plot of time-series

Graphical Parameters

If NULL, then value is chosen either by theme or with object attributes.

Examples

GDP <- fred('GDPC1', as_xts=TRUE)
GDPpot <- fred('GDPPOT', as_xts=TRUE)
GDPgap <- (GDP-GDPpot)/GDPpot*100

urate <- fred('UNRATE', as_xts=TRUE)
un <- fred('NROU', as_xts=TRUE)
cycU <- urate-un

splot(GDPgap, cycU, reg=T)
splot(GDPgap, cycU, by='cycle')
