Find the direction away from the closest point
thigmophobe(x,y)
x,y |
Numeric data vectors. Typically the x/y coordinates of plotted points. If arrays are passed, they will be silently coerced to numeric vectors. |
thigmophobe returns the direction (as 1|2|3|4 - see pos= in text) away from the nearest point to each of the points described by x and y.
A vector of directions away from the point nearest to each point.
Typically used to get the offset to automatically place labels on a scatterplot or similar using thigmophobe.labels to avoid overlapping labels. The name means "one who fears being touched".
Jim Lemon - thanks to Gustaf Rydevik for the "names" bug fix and to Steve Ellison for the suggestion about arrays.
