| plot.wt {sowas} | R Documentation |
This function plots objects of type "wt" (wavelet transform objects) from the functions wsp,wcs,wco. Modulus and (if possible) phase are plotted.
plot.wt(wt, markt = -999, marks = -999, t1 = NULL, t2 = NULL, logscale = FALSE, phase = FALSE, units = "", plottitle = "", device = "screen", file = "wt", split = FALSE, color = TRUE, pwidth = 10, pheight = 5, labsc = 1.5, labtext = "", sigplot = 3, xax = NULL, xlab = NULL, yax = NULL, ylab = NULL)
wt |
Wavelet transformation object |
markt |
Vector of times to be marked by vertical dotted lines. When set to -999 (default), no lines are plotted. |
marks |
Vector of scales to be marked by horizontal dotted lines. When set to -999 (default), no lines are plotted. |
t1 |
Starting time of the plot. If NULL (default), then the plot covers the entire range available |
t2 |
Ending time of the plot. If NULL (default), then the plot covers the entire range available |
logscale |
When TRUE, the contours are plotted in logarithmic scale |
phase |
TRUE if phase is to be plotted |
units |
character string giving units of the data sets. Default: "" |
plottitle |
character string giving plot title |
device |
"screen" or "ps" |
file |
character string giving filename of graphical output without extension |
split |
when TRUE, modulus and phase are splitted into two files. Default: FALSE |
color |
TRUE (default): color plot, FALSE: gray scale |
pwidth |
width of plot in cm |
pheight |
height of plot in cm |
labsc |
scale of labels, default: 1, for two-column manuscripts: 1.5, for presentations: >2 |
labtext |
puts a label in upper left corner of the plot |
sigplot |
0: no significance test plotted, 1: results from pointwise test, 2: results from areawise test, 3: results from both tests |
xax |
user defind x-axis |
xlab |
user defind x-labels |
yax |
user defind y-axis |
ylab |
user defind y-labels |
This function has to be called with an object of type "wt" (wavelet transformation object, output from wsp,wcs,wco). It calls plotwt(). When cv=0 or -1 is chosen, no critical values are plotted. The cone of influence is marked by black lines. If cv is a vector, the routine assumes that every value represents a critical value, which is constant in scale. If cv is a matrix, it assumes every row to contain scale dependent critical values, each row stands for one significance level. Values outside the cone of influence should be interpreted very carefully, as they result from a significant contribution of zero padding at the beginning and the end of the time series. For a better visualization, additional dotted lines marking distinct times or scales might be plotted by providing the vectors markt and marks.
