Description

Methods for TSdbi PostgreSQL time series dtabase connection.

Usage

PostgreSQL(...) "TSconnect"(q, dbname, host =  if(!is.null(Sys.getenv("PGHOST"))) Sys.getenv("PGHOST") else "localhost", ...) "TSget"(serIDs, con=getOption("TSconnection"), TSrepresentation=getOption("TSrepresentation"), tf=NULL, start=tfstart(tf), end=tfend(tf), names=NULL, TSdescription=FALSE, TSdoc=FALSE, TSlabel=FALSE, TSsource=TRUE, vintage=getOption("TSvintage"), panel=getOption("TSpanel"), ...) "TSput"(x, serIDs, con, Table=NULL, TSdescription.=TSdescription(x), TSdoc.=TSdoc(x), TSlabel.=TSlabel(x), TSsource.=TSsource(x), vintage=getOption("TSvintage"), panel=getOption("TSpanel"), ...) "TSdates"(serIDs, con, vintage=getOption("TSvintage"), panel=getOption("TSpanel"), ...) "TSdelete"(serIDs, con, vintage=getOption("TSvintage"), panel=getOption("TSpanel"), ...) "TSdescription"(x, con, ...) "TSdoc"(x, con, ...) "TSlabel"(x, con, ...) "TSsource"(x, con, ...) "TSvintages"(con)

Arguments

q
A character string indicating the query interface to use, or a database connection object.
dbname
The name of the database to which the connection should be established, omitted if q is a database connection object.
con
A database connection object.
serIDs
Character string identifiers for series to extract.
host
A character string indicating the server.
x
data series to put on the database, or a series identifier for TSdescription and TSdoc or, for print, a database connection as returned by TSconnect.
TSrepresentation
time series representation to use for the result.
names
Optional character vector to use for series names.
tf
Optional tframe to use for truncating data. (See tfwindow.)
start
Optional start date to use for truncating data. (See tfwindow.)
end
Optional end date to use for truncating data. (See tfwindow.)
TSdescription
TRUE or FALSE indicating whether description should be extracted
TSdescription.
Description to put on the database.
TSdoc
TRUE or FALSE indicating whether documentation should be extracted.
TSdoc.
Documentation to put on the database.
TSlabel
TRUE or FALSE indicating whether series label should be extracted.
TSlabel.
Short series label to put on the database.
TSsource
TRUE or FALSE indicating whether source indicator should be extracted.
TSsource.
Source indicator to put on the database.
Table
Character string indicating database table. (In TSput this is necessary if it cannot be determined automatically).
vintage
Vintage to be supplied (if supported by db).
panel
Panel to be supplied (if supported by db).

Value

Details

These are PostgreSQL methods for TSdbi. The ... argument to TSconnect can be used to pass the user name and password information to dbConnect. See the TSdbi for details and see the vignette distributed with packageTSdata for more complete examples. Package TSsql is required for functions createTSdbTables() and removeTSdbTables(). Typically createTSdbTables() will only be done once, and the tables will not be removed. These steps are done in the example below.

Run this code
    require("tfplot")
    ## Not run: 
#       conInit <- RPostgreSQL::dbConnect("PostgreSQL", dbname="test")

#       con <- TSconnect("PostgreSQL", dbname="test")
#       z <- ts(rnorm(100), start=c(1975,1), frequency=12)
#       seriesNames(z) <- "random1"
#       if(TSexists("random1", con)) TSreplace(z, con) else
