Can you create a raster stack with multiple extents?
Raster stacks not working with different extents is not entirely true, it depends on what you want to do. You can create a stack with mismatched extents by using the “quick=TRUE” argument. – Jeffrey Evans Nov 8 ’16 at 21:32
How to deal with multi-extent problem in R?
You can manage multi-extent-problem resampling your data before mask () function. This work for aligned and non-aligned pixels (for non-aligned, choose wisely method argument). Also, you can use extend to align boundaries of your data.
Is there a way to handle multiple-extent-problem?
They do have the same resolution and CRS. When I comment the mask part, the loop works, but the extents are still different. I am also not sure if I choose the right extent, since I don’t know the minimum extent. I spent a lot of time searching a way to handle this multiple-extent-problem within my data and found the crop () and mask () functions.
Can a regex match all lines of a string?
In the context of use within languages, regular expressions act on strings, not lines. So you should be able to use the regex normally, assuming that the input string has multiple lines. In this case, the given regex will match the entire string, since ” ” is present.

Why is alignextent useless in R-Stack Overflow?
Then, there are several issues with your code. In your case, alignExtent is useless since the two rasters have the same resolution and their extents correspond with regards to this resolution.
How are the layers of a polygon the same?
Both layers have the same exact Projection and Geographic coordinate systems, but do have different extents. They also have the same false easting, false northing, central meridian and datum. Is there a method of getting the points to line up on the polygon by changing extents, or is there another method that I can use?
How to add a polygon layer to a map?
Start a new, blank map document. Add your polygon layer to it. Double-click the layer in the ToC and go to the Source tab. That will tell you what coordinate system your polygon layer is in (just as an FYI). Add your table to the map. Drill down in the catalog window toolboxes to find, or type into the search window Make XY Event Layer and run it.
