Issue

I have a batch of 70+ raster files with the object name 'ncin_SST' that I created using the function stack::raster() in the raster package. I want to change the coordinate reference system (CRS) WG84/34N.

My ultimate aim is to interpolate the point data (dolphin IDs) in a shapefile to obtain the sea surface temperature (SST) values from each individual raster file within the stack of 70+ rasters.

The source of the raster files are multiple Aqua Modis netCDF files contained in one folder in my documents and I downloaded the data from the 'Ocean Color Project' from NASA. My goal is to extract the average SST per ID over the time period across all 70+ raster files from 2016-to 2021.

Firstly, I need to ensure that the shapefile and raster files have the same CRS and I have tried various different methods to achieve this output; however, unsuccessfully.

Unfortunately, I cannot share my data online due to ownership of the data.

Many thanks in advance if anyone can help with this error message.

R-code:

I'm trying to cluster time series. I also want to use Sklearn OPTICS. In the documentation it says that the input vector X should have dimensions (n_samples,n_features). My array is on the form (n_samples, n_time_stamps, n_features). Example in code further down.

My question is how I can use the Fit-function from OPTICS with a time series. I know that people have used OPTICS and DBSCAN with time series. I just can't figure out how they have implemented it. Any help will be much appreciated.

I have a function called:

I'm unable to automatically derive instances using DerivingVia on any type that uses types from optics-core like Prism'; the error I get from compiler is:

A type Prism' s a = Prism s s a a (hackage) can be thought of as a relation between some structure s and its member a, such that you can always produce the structure from the member (a -> s), but can only optionally retrieve the member from the structure (s -> Maybe a).

This model is helpful in relating a sum type to one of its constructors ... as well as (more relevant here) in route encoding and decoding. If s is the encoded route URL, and a is the route type, then we have a -> s representing the encoding function (always succeeds), and s -> Maybe a representing the decoding function (can fail).

Now, on to these pairs of functions, I want to add a "context" argument that is to be used in the encoding and decoding process (imagine that the decoding process needs to "look up" some database before successfully producing a relevant route). Basically:

I have 2 svg animations on the same page. They are each supposed to play on hover, and when the mouse leaves, they are to finish their infinite loop and stop. This works fine, unless I move from one directly to the other. The one I moved from continues to play until I move away from the second one. How can I make the first one stop when my mouse is on the second one? Below was my attempt.

I want to know which way is better to model TDE with MarkLogic.

We have XML documents with many different DateTime fields. Most of the time (99.99%), the timestamp part is of no biz use. I guess the remaining 0.01% use case is for data problem investigation like when this happened.

TDE is neat and easy to expose document data to external BI tools via ODBC. All the columnar-type of modem BI tools (Power BI) prefer separating the Date and Timestamp fields from one single Datetime field. That will improve the BI tool performance significantly.

There are two options to do that.

1. Create two different fields in TDE from the same field. See the below screenshot. Most of the time, use Date type TDE field only.

2. Create only one DateTime field in TDE and use type casting in OPTICS API or SQL (ML version of favour)

Which way is better?

here is a puzzle that I keep on bumping into and that, I believe, no previous SO question has been addressing: How can I best use the lens library to set or get values within a State monad managing a nested data structure that involves Maps when I know for a fact that certain keys are present in the maps involved?
