In the future please also report the error message.<br>
<br>
just from looking at you filepaths I bet that your path <br>
"D:/PROJECTS/PhD_Projects/Objective_1/Classification_in_R/1985/raster_data/LT51930551985065XXX01/"
<br>
is incorrect/does not exist or does not contain any files with names
matching "TIF" <br>
<br>
If you look at "allBands" it will probably say<br>
character(0)<br>
<br>
which means it didn't find any files. <br>
