描述----------Description----------
Add distance information to resampling objects
距离信息,重采样对象
用法----------Usage----------
add.distance(object, ...)
## S3 method for class 'resampling'
add.distance(object, data,
coords = c("x", "y"), ...)
## S3 method for class 'represampling'
add.distance(object, ...)
参数----------Arguments----------
参数:object
resampling or represampling object
resampling或represampling对象
参数:...
Additional arguments to dataset.distance and add.distance.resampling, respectively
额外的参数dataset.distance和add.distance.resampling,分别
参数:data
data.frame containing at least the columns specified by coords
data.frame的至少包含列指定的coords
参数:coords
(ignored by partition.cv)
(忽略的partition.cv)
Details
详细信息----------Details----------
Nearest-neighbour distances are calculated for each sample in the test set. These nrow(???$test) nearest-neighbour distances are then averaged. Aggregation methods other than mean can be chosen using the fun argument, which will be passed on to dataset.distance.
最近邻的距离,计算每个样品中的测试集。这些nrow(???$test)的最近邻距离,然后取平均值。聚合以外的其他方法mean可以选择使用fun的说法,这将被传递给dataset.distance。
值----------Value----------
A resampling or represampling object containing an additional $distance component in each resampling object. The distance component is a single numeric value indicating, for each train / test pair, the (by default, mean) nearest-neighbour distance between the two sets.
Aresampling或represampling对象,它包含一个额外的$distance组成部分,每一个resampling对象。组件是distance一个单一的数值表明,每一个train/test对,(默认情况下,意味着两套)最近的邻居之间的距离。

实例----------Examples----------
data(ecuador) # Muenchow et al. (2012), see ?ecuador[明肖等。 (2012年),厄瓜多尔,看到了吗?]
nsp.parti = partition.cv(ecuador)
sp.parti = partition.kmeans(ecuador)
nsp.parti = add.distance(nsp.parti, ecuador)
sp.parti = add.distance(sp.parti, ecuador)
# non-spatial partioning: very small test-training distance:[非空间分割方式非常小的测试培训的距离:]
nsp.parti[[1]][[1]]$distance
# spatial partitioning: more substantial distance, depending on number of folds etc.[空间分割较大幅度的距离,根据褶皱数目等]
sp.parti[[1]][[1]]$distance
