r - Error while loading packages from non-default library paths -


how load packages not present in .libpaths()??

checking libraries

.libpaths() # [1] "/m/home/userxyz/unix/r/x86_64-pc-linux-gnu-library/3.4" # [2] "/usr/local/lib/r/site-library"                                    # [3] "/usr/lib/r/site-library"                                          # [4] "/usr/lib/r/library"

adding new path

newpath = "/m/home/userxyz/unix/r/x86_64-pc-linux-gnu-library/devpacks/"  .libpaths( c( .libpaths(), newpath) )  libpaths() # [1] "/m/home/userxyz/unix/r/x86_64-pc-linux-gnu-library/3.4"      # [2] "/usr/local/lib/r/site-library"                                         # [3] "/usr/lib/r/site-library"                                               # [4] "/usr/lib/r/library"                                                    # [5] "/m/home/userxyz/unix/r/x86_64-pc-linux-gnu-library/devpacks"

installing development version of package

withr::with_libpaths(new = newpath, devtools::install_github('tidyverse/ggplot2'))

loading installed package

library(ggplot2, lib.loc = "/m/home/userxyz/unix/r/x86_64-pc-linux-gnu-library/devpacks")

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
