[R] spatstat error

[Blaser Nello]

Why do you first say min(Datos$x) and then give the numeric value of this minimum? Just delete all numerical values:
	danta=ppp(Datos$x, Datos$y, c(min(Datos$x), max(Datos$x)), c(min(Datos$y), max(Datos$y)))
or if you really want to type the numeric constants (probably a bad idea)
	danta=ppp(Datos$x,Datos$y,c(1177842,1180213),c(1013581,1015575))

Thank you so much
