Thanks for reporting Micha, and creating a reprex on github Andy; the problem seems to be fixed, now. Best regards, On 10/23/19 2:22 PM, Andy Teucher wrote: > I’m fairly certain this is a bug in stars; I opened an issue here: > https://github.com/r-spatial/stars/issues/223 >

Thanks to both of you for identifying the problem so quickly, and offering a workaround! On 23/10/2019 21:25, Vijay Lulla wrote: Andy, you're spot on!  This is because stars:::`[.stars` is only looking for variables and not expressions (line 44 in the function!).  Your example gets around

Re: [R-sig-Geo] Implementing a rolling window for stars object

Andy, you're spot on! This is because stars:::`[.stars` is only looking for variables and not expressions (line 44 in the function!). Your example gets around it by creating an object in the environment (parent.frame) which is then consulted in the `eval`. Sorry for tmi! HTH, Vijay. On Wed,

I’m fairly certain this is a bug in stars; I opened an issue here: https://github.com/r-spatial/stars/issues/223 Cheers, Andy Teucher > On Oct 23, 2019, at 10:42 AM, Andy Teucher wrote: > > Interesting - there’s some rlang/tidy evaluation

Re: [R-sig-Geo] Implementing a rolling window for stars object

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 <-

Re: [R-sig-Geo] Implementing a rolling window for stars object

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

[R-sig-Geo] Implementing a rolling window for stars object

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:
