Special Daily Time Series

Description

Special daily 'timeSeries' functions.

dummyDailySeries Creates a dummy daily 'timeSeries' object,
alignDailySeries Aligns a daily 'timeSeries' to new positions,
rollDailySeries Rolls daily a 'timeSeries' on a given period,
ohlcDailyPlot Plots open high low close bar chart,
dummySeries Creates a dummy monthly 'timeSeries' object

Usage

dummyDailySeries(x = rnorm(365), units = NULL, zone = "",
    FinCenter = "")
alignDailySeries(x, method = c("before", "after", "interp", "fillNA",
    "fmm", "periodic", "natural", "monoH.FC"),
    include.weekends = FALSE, units = NULL, zone = "",
    FinCenter = "", ...)
rollDailySeries(x, period = "7d", FUN, ...)
ohlcDailyPlot(x, volume = TRUE, colOrder = c(1:5), units = 1e6,
    xlab = c("Date", "Date"), ylab = c("Price", "Volume"),
    main = c("O-H-L-C", "Volume"), grid.nx = 7, grid.lty = "solid", ...)

Arguments

colOrder

[ohlcDailyPlot] -
an integer vector which gives the order of the prices and the volume in the input object. By default the following order of columns from 1 to 5 is assumed: Open, high, low, close, and volume.

FinCenter

a character with the the location of the financial center named as "continent/city".

FUN

the function to be applied.
[applySeries] -
a function to use for aggregation, by default colAvgs.

grid.lty, grid.nx

[ohlcDailyPlot] -
The type of grid line and the number of grid lines used in the plot.

include.weekends

[alignDailySeries] -
a logical value. Should weekend dates be included or removed from the series.

main

[ohlcDailyPlot] -
a character string to title the price and volume plot.

method

[alignDailySeries] -
the method to be used for the alignment. A character string, one of "before", use the data from the row whose position is just before the unmatched position, or "after", use the data from the row whose position is just after the unmatched position, or "linear", interpolate linearly between "before" and "after".

period

[rollDailySeries] -
a character string specifying the rollling period composed by the length of the period and its unit, e.g. "7d" represents one week.

units

[allignDailySeries] -
an optional character string, which allows to overwrite the current column names of a timeSeries object. By default NULL which means that the column names are selected automatically.
[ohlcDailyPlot] -
a numeric value, specifying in which multiples the volume should be referenced on the plot labels. By default 1e6, i.e. in units of 1 Million.

volume

[ohlcDailyPlot] -
a logigical value. Should a volume plot added to the OHLC Plot. By default TRUE.

x

an object of class timeSeries.

xlab, ylab

[ohlcDailyPlot] -
two string vectors to name the x and y axis of the price and volume plot.

zone

the time zone or financial center where the data were recorded.

...

arguments passed to interpolating methods.

Value

dummyDailySeries
creates from a numeric matrix with daily records of unknown dates a timeSeries object with dummy daily dates.

alignDailySeries
returns from a daily time series with missing holidays a weekly aligned daily timeSeries object

rollDailySeries

returns an object of class timeSeries with rolling values, computed from the function FUN.

ohlcDailyPlot displays a Open-High-Low-Close Plot of daily data records.

Examples

## Use Microsofts' OHLCV Price Series -
   head(MSFT)
   end(MSFT)


## Cut out April Data from 2001 -
   Close <- MSFT[, "Close"]
   tsApril01 <- window(Close, start="2001-04-01", end="2001-04-30")
   tsApril01

## Align Daily Series with NA -
   tsRet <- returns(tsApril01, trim = TRUE)
   GoodFriday(2001)
   EasterMonday(2001)
   alignDailySeries(tsRet, method = "fillNA", include.weekends = FALSE)
   alignDailySeries(tsRet, method = "fillNA", include.weekends = TRUE)

## Align Daily Series by Interpolated Values -
   alignDailySeries(tsRet, method = "interp", include.weekend = FALSE)
   alignDailySeries(tsRet, method = "interp", include.weekend = TRUE)
