Remove holes in polygon
问题 I am trying to solve the following problem in R : I have a polygon object defined by a list l with two components x and y. The order defines the edges of the polygon. For instance : l=list( x=c(-1.93400738955091,0.511747161547164,1.85047596846401,-1.4963460488281,-1.31613255558929,-0.0803828876660542,1.721752044722,-0.724002506376074,-2.08847609804132,2.13366860069641), y=c(-1.02967154136169,1.53216851658359,-1.39564869249673,-1.21266011692921,1.6419616619241,-1.87141898897228,0
