thigmophobe(x,y)
x,y |
Numeric data vectors. Typically the x/y coordinates of plotted points. |
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".
