Installation of rdyncall package for R

Question

Hi I have a problem with installation rdyncall. rdyncall is in archive and I tried this:

url = "http://cran.r-project.org/src/contrib/Archive/rdyncall/rdyncall_0.7.5.tar.gz"

pkgFile = "rdyncall_0.7.5.tar.gz"

download.file(url = url, destfile = pkgFile)

install.packages(pkgs=pkgFile, type="source",repos=NULL)

unlink(pkgFile)

after install.packages("...") I got this error:

ERROR: failed to lock directory 'C:/Users/user/Documents/R/win-library/3.1' for modifying
Try removing 'C:/Users/user/Documents/R/win-library/3.1/00LOCK-rdyncall'
Warning in install.packages :
  running command '"C:/PROGRA~1/R/R-3.1.2/bin/x64/R" CMD INSTALL -l "C:\Users\user\Documents\R\win-library\3.1" "rdyncall_0.7.5.tar.gz"' had status 3
Warning in install.packages :
  installation of package ‘rdyncall_0.7.5.tar.gz’ had non-zero exit status

I have removed permission in windows "only to read" but nothing. I tried it at 3.1.2, 3.0, and 2.15 version of R.

I try it at Win8 and it is working. At win 8.1 and win7 it is not working. I dont known why, but if I after that copy "R Folder" from program files (from Win8) to Win 8.1. It is working.

The rdyncall package has recently been updated on github. To install it just do

library(remotes)
remotes::install_github("hongyuanjia/rdyncall")
library(rdyncall)

The SDL, SDL_image and SDL_mixer DLLs (version 1.2) (on Windows) have to be installed first from https://libsdl.org/release/, https://www.libsdl.org/projects/SDL_image/release/ and https://www.libsdl.org/projects/SDL_mixer/release/) (the 64 bit DLLs are to be put underR-4.2.1/bin/x64`) or using

source("https://raw.githubusercontent.com/Jean-Romain/lidRviewer/master/sdl.R")

On Ubuntu they can be installed using

sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2

An example to use rdyncall for the fast display of raster images using SDL & OpenGL is given here.
