composite.field {clim.pact} | R Documentation |
Produce composites of maps based on station observations,
weights, or years. For a station object, assign +/- 1 weights
according to whether the values stored in val
(monthly station
objects) are greater than mean + sd or less than
mean - sd.

x |
A field object. |
y |
A station object, a vector consisting of [-1,0,+1] or a vector consisting of the years (negative values are used for negative phase, eg. c(1991,1993,1998,-1961,-1963,-1994). |
lsig.mask |
FLAG: mask the regions not statistically significant. |
sig.lev |
Level of significance. |
s |
Threshold for defining whether y is high or low = s *
sd(y). |
mon |
Month to analyse. |
lty |
Contour line type. |
col |
Contour line colour. |
lwd |
Contour line width. |
main |
Main title. |
sub |
subtitle. |
A map object.
