我在制作光栅堆栈时遇到麻烦
当我读取光栅文件时(下面是代码)
clim_fut_26_2050 <- stack(list.files(path= paste('D:/hd26bi50/', sep=''), pattern='tif', full.names=TRUE ))
列表文件结果
list.files(path= paste('D:/hd26bi50/', sep='')) = [1] "D:/hd26bi50/bio1.tif" "D:/hd26bi50/bio10.tif" "D:/hd26bi50/bio11.tif" "D:/hd26bi50/bio12.tif" "D:/hd26bi50/bio13.tif"
[6] "D:/hd26bi50/bio14.tif" "D:/hd26bi50/bio15.tif" "D:/hd26bi50/bio16.tif" "D:/hd26bi50/bio17.tif" "D:/hd26bi50/bio18.tif"
[11] "D:/hd26bi50/bio19.tif" "D:/hd26bi50/bio2.tif" "D:/hd26bi50/bio3.tif" "D:/hd26bi50/bio4.tif" "D:/hd26bi50/bio5.tif"
[16] "D:/hd26bi50/bio6.tif" "D:/hd26bi50/bio7.tif" "D:/hd26bi50/bio8.tif" "D:/hd26bi50/bio9.tif"
文件顺序乱(没有顺序)
names(clim_fut_26_2050)
[1] "bio1" "bio10" "bio11" "bio12" "bio13" "bio14" "bio15" "bio16" "bio17"
"bio18" "bio19" "bio2" "bio3" "bio4" "bio5" "bio6" "bio7"
[18] "bio8" "bio9"
如何重新排序这些图层？
帮帮我吧T.T
最佳答案
mixedsort函数位于 gtools库可以对列表中的对象重新排序:
library(gtools)
setwd('D:/hd26bi50')
s <- stack(mixedsort(list.files(pattern='tif', full.names=TRUE )))
