ggplot2 - Wrap column name text in ggpairs in R -


i using ggpairs , while plotting matrix, receive matrix follows

enter image description here

as can see, of text length large , hence text not seen completely. there anyway can wrap text visible completely.

code

ggpairs(df)

i want text wrap can seen this

enter image description here

you can use labeller argument of ggpairs pass function applied facet strip text.

ggplot have nice ready function label_wrap_gen() wrap long labels.

by default ggpairs use column names labels, , can't contain spaces. label_wrap_gen() need spaces split labels on multiple rows.

this solution:

library(ggplot2) library(ggally) df <- iris  colnames(df) <- make.names(c('long colname',                    'quite long colname',                    'longer tha usual colname',                   'i\'m not sure should colname',                   'the ever longest colname 1 should allowed use'))  ggpairs(df,          columnlabels = gsub('.', ' ', colnames(df), fixed = t),          labeller = label_wrap_gen(10))

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...
