r - Parse JSON to a dataframe -


not sure how this:

i have stored (in a):

[   "multipolygon (((-95.0000000372529 40.999989970587194, -94.5000000372529 40.999989970587194, -94.5000000372529 40.499989970587194, -95.0000000372529 40.499989970587194)))" ]  typeof(a) # prints "character" class(a)  # prints "json"

and convert data.frame looks (no need round numbers, easier type that)

  x1  x2 1 -95 40 2 -94 40 3 -94 40 4 -95 40

i tried

a.df<-as.data.frame(as.matrix(a))

but prints

 v1 1 [\n  "multipolygon (((-95.0000000372529 40.999989970587194, -94.5000000372529 40.999989970587194, -94.5000000372529 40.499989970587194, -95.0000000372529 40.499989970587194)))"\n]\n 

library(sf) library(jsonlite) library(tidyverse)  x <- fromjson('[   "multipolygon (((-95.0000000372529 40.999989970587194, -94.5000000372529 40.999989970587194, -94.5000000372529 40.499989970587194, -95.0000000372529 40.499989970587194)))" ]')  map(x, st_as_sfc) %>%   map(~as.data.frame(.[[1]][[1]])) ## [[1]] ##      x1       x2 ## 1 -95.0 40.99999 ## 2 -94.5 40.99999 ## 3 -94.5 40.49999 ## 4 -95.0 40.49999

now:

wkt2geojson('[   "multipolygon (((-95.0000000372529 40.999989970587194, -94.5000000372529 40.999989970587194, -94.5000000372529 40.499989970587194, -95.0000000372529 40.499989970587194)))" ]')

also kinda works tosses warnings.

knowing actual source created wkt in such configuration wld helpful

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
