sqplot: Plot of Non-constant Solar Quiet Daily Variation

In iWISA: Wavelet-Based Index of Storm Activity

Description

This function visualizes the estimated non-constant solar quiet daily variation of each station. Users would define how many graphs to be put into one page, The default set is 2 graphs per page.

Usage

sqplot(x, start = NULL, end = NULL, n.station = NULL,
  graphs.per.page = 2, station.names = NULL, Title = NULL, ...)

Arguments

x	estimation of solar quite variations from SQ
start	start date of records for magnetic activities. See examples
end	end date of records for magnetic activities. See examples
n.station	number of studied stations
graphs.per.page	how many graphs combined in one plot page. Default number is 2
station.names	NULL (indicating no station names) or a vector strings for station names.
Title	title of sqplot
...	additional arguments

Details

This function is used to visualize estimated Sq variation. Specifying the names of each stations would add station names at y-axis.

## data sets.

## Colatitude and longitude of geomagnetic observatories.
## Not run: 
coord=matrix(c(124.43, 19.23, 53.77,140.18,68.68,202.00,71.89,293.85),nrow=2,ncol=4)


## Estimation of SI index
index.sample<- SAIndex(record, coord, wf="la8")
si.v<-index.sample$SI


## generate datetime for one week period
start.date="2001-3-1"
end.date="2001-4-30"

## estimation of sq
Sq<- SQ (datasq, si.v=si.v, wf = "la8")

sqplot(Sq, Title="Sq variation", start = start.date, end=end.date, n.station=4,
      graphs.per.page=2, station.names=c("ABG","PHU","TUC","FRD"))
