Attach a 'timeSeries' to the search path

Attaches a "timeSeries" object to the search path.

Usage

# S4 method for timeSeries
attach(what, pos = 2, name = deparse(substitute(what)), 
    warn.conflicts = TRUE)

Note

The function detach from the base package can be used to detach the attached objects.

Arguments

name

alternative way to specify the database to be attached. See for details help(attach, package = base).

pos

an integer specifying position in search() where to attach the database. See for details help(attach, package = base).

warn.conflicts

a logical value. If TRUE, warnings are printed about conflicts from attaching the database, unless that database contains an object .conflicts.OK. A conflict is a function masking a function, or a non-function masking a non-function. See for details help(attach, package = base).

what

database to be attached. This may currently be a "timeSeries" object, a data.frame, a list, an R data file created with save, NULL, or an environment. See for details help(attach, package = base).

Value

the environment, invisibly, with a name attribute

Examples

## Load Microsoft Data Set - 
   x <- MSFT[1:10, ]
   colnames(x)
#> [1] "Open"   "High"   "Low"    "Close"  "Volume"
   
## Attach the Series and Compute the Range - 
   attach(x)
   range <- High - Low
   range
#>  [1] 3.7500 1.2500 2.6875 2.5625 3.3125 2.0625 2.0000 2.0000 2.7500 1.7500
   
## Convert Vector to a \code{"timeSeries"} Object -
   timeSeries(data=range, charvec=time(x), units="Range")
#> GMT 
#>             Range
#> 2000-09-27 3.7500
#> 2000-09-28 1.2500
#> 2000-09-29 2.6875
#> 2000-10-02 2.5625
#> 2000-10-03 3.3125
#> 2000-10-04 2.0625
#> 2000-10-05 2.0000
#> 2000-10-06 2.0000
#> 2000-10-09 2.7500
#> 2000-10-10 1.7500
   
## Detach the series from the search path -
   detach("x")
   ans <- try(High, silent=TRUE)
   cat(ans[1])
#> Error in eval(expr, envir, enclos) : object 'High' not found
