Description Usage Arguments Details See Also Examples
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.
1 2 |
x |
estimation of solar quite variations from |
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 |
This function is used to visualize estimated Sq variation. Specifying the names of each stations would add station names at y-axis.

index.sample<- SAIndex(record, coord, wf="la8")
