使用R列出LANDSAT文件的一些波段

Question

我有一个文件夹与一个陆地卫星图像与8个tif文件。

list.files("C:/Users/Documents/04.HUMEDALES/L5__002072-09MAY-2006",  pattern = glob2rx("*.TIF"),full.names = TRUE) 

如图所示：

[1] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B1.TIF" 
[2] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B2.TIF" 
[3] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B3.TIF" 
[4] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B4.TIF" 
[5] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B5.TIF" 
[6] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B6.TIF" 
[7] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_B7.TIF" 
[8] "C:/Users/Documents/L5__002072-09MAY-2006/LT05_L1TP_002072_20060509_20161121_01_T1_BQA.TIF"

我怎么能只列出乐队1到5和7的tif文件？我找不到合适的图案。这是我得到的最接近的文件(只删除最后一个文件: BQA.tif)

list.files("C:/Users/Documents/04.HUMEDALES/L5__002072-09MAY-2006", pattern = glob2rx("*B?.TIF"), full.names = TRUE)

Answer 1

从这组文件中：

> list.files(".")
 [1] "bar-foo_B1.tif"  "bar-foo_B2.tif"  "bar-foo_B3.tif"  "bar-foo_B4.tif" 
 [5] "bar-foo_B5.tif"  "bar-foo_B6.tif"  "bar-foo_B7.tif"  "bar-foo_BQA.tif"
 [9] "foo_B1.tif"      "foo_B2.tif"      "foo_B3.tif"      "foo_B4.tif"     
[13] "foo_B5.tif"      "foo_B6.tif"      "foo_B7.tif"      "foo_BQA.tif"    

我可以使用此正则表达式进行选择，该正则表达式匹配任何内容(.*)、B、1至5和7，然后是".tif“，然后是文件名的末尾：

> list.files(".",pattern=".*B[123457]\\.tif$", ignore.case=TRUE)
 [1] "bar-foo_B1.tif" "bar-foo_B2.tif" "bar-foo_B3.tif" "bar-foo_B4.tif"
 [5] "bar-foo_B5.tif" "bar-foo_B7.tif" "foo_B1.tif"     "foo_B2.tif"    
 [9] "foo_B3.tif"     "foo_B4.tif"     "foo_B5.tif"     "foo_B7.tif"
