r - 在 R 中执行 gstat 的克里格函数时出错

Question

我想使用 gstat 包执行普通克里金法。
我只有 17 个位置，这对于 OK 来说是不够的，所以我还使用了每个节点的时间数据作为辅助数据来构建变异函数。但是，我想出了这个错误，请指导我解决这个问题。此外，gstat 无法处理近距离坐标，如果您知道 r 中的另一个强大的包，请告诉我好吗。

我正在使用的代码:

mat <- transform(mat, E = as.numeric(mat$E), N = as.numeric(mat$N))
 coordinates(mat) <- ~E+N
E.range <- as.integer(range(mat@coords[,1]))
N.range <- as.integer(range(mat@coords[,2]))
mat.new <- expand.grid(x=seq(from=E.range[1], to=E.range[2], by=35), y=seq(from=N.range[1], to=N.range[2], by=35) )
mat.new <- SpatialPoints(mat.new)
gridded(mat.new) <- FALSE

mat.mv=vgm(psill=1, model="Exp", nugget=.2, range=550)
mat.ok <- krige(X0~1, locations=mat.new  ,model=mat.mv , newdata=mat.new , data=mat)

错误:

Error in gstat(formula = formula, data = locations, model = model, beta = beta,  : 
  formal argument "data" matched by multiple actual arguments

并将代码修改为:

mat.mv=vgm(psill=1, model="Exp", nugget=.2, range=550)
mat.ok <- krige(X0~1, mat, mat.new, mat.mv)

我想出了这个错误:

[使用普通克里金法]

"chfactor.c", line 131: singular matrix in function LDLfactor()

Answer 1

您必须使用函数 zerodist() 检查您的数据是否不包含任何重复项。 .如果有重复，使用函数remove.duplicate()删除重复的行。
