我使用以下函数创建了一个lhs
对象:
am321.lhs <- lxy.lhs(am321.lxy.every4th, k=24, s=0.07, kmin=12, save.hulls=TRUE)
但是,当我尝试通过以下调用创建isopleth时,我收到错误。我已粘贴下面的控制台输出:
am321.lhs <- lhs.iso.add(am321.lhs)
使用最近邻选择模式:固定k 构建船体和船体指标......
am321.pts26934.k24.s0.07.kmin12 Found a suitable set of nearest neighbors Identifying the boundary points for each parent point |++++++++++++++++++++++++++++++++++++++++++++++++++| 100% Converting boundary points into polygons |++++++++++++++++++++++++++++++++++++++++++++++++++| 100% Calculating area and perimeter...Done. Calculating the time span of each hull...Done. Identifying enclosed points...Done. Computing density isopleths Error in get("hulls2iso.rgeos", 1) : object 'hulls2iso.rgeos' not found
如果有任何帮助,我将不胜感激。
谢谢你 Karpa

我最近遇到了同样的错误,得到了Andy Lyons的以下建议:
您在包中遇到了错误。请将软件包更新到版本1.40(或更高版本),它应该可以使用。
packageVersion("tlocoh")
update.packages(oldPkgs="tlocoh", repos="http://R-Forge.R-project.org")
