我正在尝试运行该功能

gw.dist(dp.locat, rp.locat, focus=0, p=2, theta=0, longlat=F)

在 R 包 GWmodel 中。

随文档提供的示例显示以下内容：

首先创建一些模拟数据

dp<-cbind(sample(100),sample(100))

dp

       [,1] [,2]
  [1,]   45   97
  [2,]   37   55
  [3,]   83   69
  [4,]   14   11
  [5,]   49   31
  [6,]   91   35
  [7,]   54   27
  [8,]   23   16
  [9,]   28   10
 [10,]   99   77
 [11,]    2  100
 [12,]   38   89
 [13,]   20   45
...
[100,]   74   66

然后应用函数

dist.v1<-gw.dist(dp.locat=dp, focus=5, p=2, theta=0, longlat=FALSE)

这给出了这个结果：

我正在尝试对自己的数据做同样的事情

locations <- cbind(Eng$Latitude,Eng$Longitude)

locations

             [,1]      [,2]
    [1,] 51.49752 -0.149860
    [2,] 53.80765 -3.045101
    [3,] 51.55375 -0.259466
    [4,] 50.80333 -1.088333
    [5,] 50.90520 -1.393890
    [6,] 55.54942 -1.728630
    [7,] 51.54975 -0.117760
    [8,] 52.05692  1.160946
    [9,] 51.50116 -0.226078
   [10,] 51.46406 -0.117073   
   ...
  [351,] 52.18220 -0.804491

将函数设置为：

dist.v1<-gw.dist(locations.locat=locations, focus=5, p=2, theta=0, longlat=FALSE)

但是，我收到错误：

ERROR: unused argument (locations.locat = locations)

我怎么了？谢谢。

你有一个错字：论点是dp.locat，不是locations.locat。
