Classify wind direction and speed records
Classifies wind direction and speed records into a matrix of percentages of observations in speed and direction bins.
bin.wind.records(winddir,windspeed,ndir=8,radians=FALSE, speed.breaks=c(0,10,20,30))
winddir |
A vector of wind directions. |
windspeed |
A vector of wind speeds corresponding to the above directions. |
ndir |
Number of direction bins in a compass circle. |
radians |
Whether wind directions are in radians. |
speed.breaks |
Minimum wind speed for each speed bin. |
bin.wind.records bins a number of wind direction and speed records into a matrix of percentages of observations that can be used to display a cumulative wind rose with oz.windrose The defaults are those used by the Australian Bureau of Meteorology.
A matrix of percentages in which the rows represent wind speed categories and the columns represent wind direction categories.
