如何在R中对栅格堆栈进行预白化？

Question

我一直在使用spatialEco包来确定趋势，p值和tau值（raster.kendal）。它的p值最高为0.2，所以想做预告。
虽然我使用kendall函数进行预发通知，但ASCII和GTIFF格式均出现错误。 （错误1）。当我选择文件而不是堆栈时，它给出了另一个错误（error2）

1. ascidata <- list.files(path = "F:/ShareBoth/../ascii/", full.names = TRUE) length(ascidata) asciistack <- stack(ascidata) prewit <- kendall(asciistack, p.value = TRUE, prewhiten = TRUE)

2. tifdata <- list.files(path = "F:/ShareBoth/../tif/", full.names = TRUE) length(tifdata) tifstack <- stack(tifdata) prewit <- kendall(tifstack, p.value = TRUE, prewhiten = TRUE)

给出 错误1：Error in y[!is.na(y)] : object of type 'S4' is not subsettable

1. tifdata <- list.files(path = "F:/ShareBoth/../tif/", full.names = TRUE) length(tifdata) tifstack <- stack(tifdata) prewit <- kendall(tifstack$layer1, p.value = TRUE, prewhiten = TRUE)

它给出了第二个错误 错误2：Error in model.frame.default(formula = y ~ 1, na.action = function (object, :object is not a matrix
