Using multiple dat files

100 weather tables using read.tables., right? Using file.choose() doesn't
change the work."
Yes. With that many files, file.choose() does not make sense. However, I
still do not understand what is the problem with using lapply() on the
character vector of file names with read.table() as you did in your

Using multiple dat files
Dear community
To import multiple .dat weather files I am using list.files().
I intend to use the R package ?ClimInd? to calculate different agroclimatic indicators.
Question: Is there another solution to import multiple .dat files so that I can select elements from the list, e.g. one specific weather file (example AAR_DailyWeather)?

Import multiple tif raster
Dear community
Dear Ivan
Thanks a lot. The code works now. Solution: direct and full path to the .tif files.
I confused back and forward slash
#first import all files in a single folder as a list

Thanks a lot.
I tried now to provide the full path. However probably the "?" in the path produces the error, would that be possible?

Many thanks Ivan
Use is.na() on getValues() outputs, combine the two masks using the | operator to get a mask of values that are missing in either raster, then negate the mask to choose the non-missing values:
all.equal(getValues(r1)[!mask], getValues(r2)[!mask])
--> what do you mean by use is.na() in getValues(). So I need to call getValues a second time? I suppose you mean to first

Thanks a lot.
I used:

No warning now with Helvetica
Additionally I used "sans", similarly no warning in the first part.

Dear Ivan
Many thanks.
Using my own dataset, my "s" is a layer shape file.
Somewhere I need to define : snew<-s$Unterregio
I tried it to do it before stack(), but it seems to be the wrong way. Do you have any suggestion?

That's not really a reprex Sibylle.? I did try to use it to see if I
could work out what you were trying to do and help but there is so much
in there that I suspect is distraction from the notch issue and its
error message.
Please can you give us something stripped of all unecessary things and
tell us what you want?

"Is it true that all.equal just compares y values?"
The following may be a bit more than you may have wanted, but I hope
it is nevertheless useful.
The first place you should go to for questions like this is the Help
system, not here, i.e.
?all.equal
When you do this, you will find that all.equal() is a so-called S3
generic function, which, among other things, means that it works

?? The OP's original problem is that the all.equal method for raster
objects (raster:::all.equal.raster), which is a wrapper around the
compareRaster() function, compares a bunch of different properties of
rasters (extent, resolution, values, etc.) and only returns a single
overall logical (TRUE/FALSE) value. OP wanted to see the magnitude of
the difference (as you could get for more

Dear Ivan
Thanks a lot for this very nice example.
Is it true that all.equal just compares y values?
Based on this help here I think so and the value I got is the difference for the y-values.
https://www.statology.org/all-equal-function-r/
However, here I see x and y testing?
https://www.rdocumentation.org/packages/base/versions/3.6.2/topics/all.equal
I am actually interested in the x values

Ah...I see.
Perhaps, then, the maintainer should be contacted, as the desired
functionality seems similar to that provided in other all.equal
methods. I realize that this may often not elicit a (prompt) response.

Quite nice book recommendation.
Yes indeed my raster "s" (the shape file for the boxplot classes) has several layers. That's way I tried to select a layer by " s<-sf$Unterregio".
