标签:r package alphahull position points
I have define an area with alphahull
but I can‘t get the right point in the area.
for example:
> z.def$x [,1] [,2] [1,] 13.61808 26.67013 [2,] 12.82682 23.04007 [3,] 12.96585 19.08577 [4,] 14.64468 18.93133 [5,] 18.81814 22.18428 [6,] 18.66133 28.07588 > for (x in seq(97700, 97801, 20)) { for (y in seq(1000000,1000501, 50)) { if (inahull(z.def, c(x,y))) { print (c(x,y)) } } } This will print many numbers.
