how can - create 2 input data set referenced in @script example exec sp_execute_external_script @language = n'r' , @script = n' outputdataset <- inputdataset' , @input_data_1 = n'' , @input_data_2 = n'' -- line. , @input_data_1_name = n'inputdataset' , @output_data_1_name = n'outputdataset' result sets ((plot nvarchar(max))); you have use @params if want more 1 input/output. assign data parameter of exact same name right after it. exec sp_execute_external_script @language = n'r' , @script = n' notusedagain <- seconddataset; outputdataset <- inputdataset ' , @input_data_1 = n'' , @params = n'@seconddataset int' , @seconddataset = 1 result sets ((plot nvarchar(max)));

i have queryset in view.py: somevalue = list(a.objects.filter(x=x_number, timestamp__gte=a_time, timestamp__lte=b_time) \ .order_by('timestamp').values_list('timestamp', 'some_index').annotate( some1=dosomething('some_index'), some2=dosomething('some_index_2'), combined_some=(f('some1') + f('some2')) )) so somevalue looks this: somevalue = [(datetime.datetime(2017, 7, 20, 23, 53, 51, tzinfo=<utc>), 2l, 10.1, 2.4, 12.5), (datetime.datetime(2017, 7, 20, 23, 54, 51, tzinfo=<utc>), 8l, 5.5, 6.4, 11.9), (datetime.datetime(2017, 7, 20, 23, 55, 51, tzinfo=<utc>), 4l, 7.2, 2.0, 9.2),...] my goal access somevalue , combined_some this: combined_some = [(datetime.datetime(2017, 7, 20, 23, 53, 51, tzinfo=<utc>), 12.5), (datetime.datetime(2017, 7, 20, 23, 54, 51, tzinfo=<utc>), 11.9), (datetime.datetime(2017, 7, 20, 23, 55, 51, tzinfo=<utc...

this question has answer here: store mouse click event coordinates matplotlib 2 answers detecting mouse event in image matplotlib 2 answers determine button clicked subplot in matplotlib 2 answers i have 2 images want following using python 3.6 1- plot both images side side 2- click on 1 image , output corresponding pixel coordinates 3- click on second image , corresponding pixel coordinates note: question different because has work on 2 images finding axis click event happening. i think best way have function identifies axis clicking on , gets clicked coordinates. couldn't find of resources 2 images, found on 1 image.

i'd implement following behavior: let x = try do_some_computation () | some_error -> exit_my_program () in ... of course, raise exception such as: let exit_my_program () = failwith "...." but, i'd like: let exit_my_program () = print.printf "some error message\n"; exit 1 the issue i'm having exit 1 has type 'a deferred.t , it's not going typecheck. i'm wondering if there's exit function type 'a use in context, or maybe more generally, function force deferred. the function pervasives.exit of type int -> 'a . don't know async, don't know if it's plan use function. it's easy believe might not such plan if want things wind down carefully.
