Thanks for reporting Micha, and creating a reprex on github Andy; the
problem seems to be fixed, now.
Great, thanks for the quick response.
I guess reinstalling stars from CRAN should get the fix?
Best regards,

Interesting - there’s some rlang/tidy evaluation trickery going on there that I
couldn’t quite figure out (I think it might be searching for yr in the wrong
environment), but defining your range as a single variable, and putting that in
the square brackets seems to work for me:
rng <- yr:last_yr
stars_window = ci_stars[,,,rng]

Hi Micha,
I can see two problems immediately with your code:
1. you are using a double-colon (yr::last_yr) - the double colon is used for
looking for an object in a package, so it is looking for object ‘yrs’ in
package ‘yr’, which obviously doesn’t make sense. Use a single colon to create
a range (like you did with 2:6)
2. the object ‘last_yr’ is never defined, so even if you used a single colon
to define the range yr:last_yr, it would fail as it would not be able to find
object ‘last_yr’
Thanks,
I fixed those typos (corrected script attached) and I still get this error:
micha@tp480:R$ Rscript stars_window.R

I am trying to run a function (mk.test to find MannKendall trends) using st_apply over a
"rolling" window for a time series of rasters in a stars object.
When I use subscript notation to slice out the window dimension with a looping
variable I get an error:
Error in loadNamespace(name) : there is no package called ‘yr’
Calls: [ ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted
However If I replace the subscript with integers it works fine. (see attached)
What is the correct way to work this out?
Attached is a reprex with a small subset of my data. (The script starts with a
long structure, code is at the end)
Thanks
