join.asc finds the value of a mapped variable at some specified locations.
join.kasc is the same function as join.asc, with several maps.

1 2	join.asc(pts, x) join.kasc(pts, w)

`x`	an object of class `asc`
`w`	an object of class `kasc`
`pts`	a data frame with two columns containing the x and y coordinates of the points to be placed on the map

join.asc returns a vector with length equals to the number of points in pts.
join.kasc returns a data frame with a number of columns equals to the number of variables in the object of class kasc, and with each row corresponding to the rows of pts.

kasc and asc

data(puechabon)
x <- puechabon$kasc

## for each relocation, finds the values of the variables in x
toto <- join.kasc(pts = cbind(puechabon$locs$X, puechabon$locs$Y), x)
toto[1:4,]
