You can install the in-development version of the package fromGitHub too:

if (!require(remotes)) {install.packages("remotes")}remotes::install_github("r-hyperspec/hyperSpec")

NOTE 1:Usually, "Windows" users need to download, install, and properly configureRtools (seethese instructions) to make the code above work.

NOTE 2:This method willnot install package's documentation (help pages and vignettes) into your computer.So you can either use theonline documentation or build the package from source (see the next section).

1. From thehyperSpec's GitHubrepository:

   • If you use Git,git clone the branch of interest.You may need to fork it before cloning.
   • Or just choose the branch of interest (1 in Figure below), download a ZIP archive with the code (2, 3), and unzip it on your computer.
     

2. Open the downloaded directory in RStudio (preferably, as an RStudio project).

   • The code below works correctly only if your current working directory coincides with the root of the repository, i.e., if it is in the directory that contains fileREADME.md.
   • If you open RStudio project correctly (e.g., by clickingproject.Rproj icon in the directory), then the working directory is set correctly by default.

3. In the RStudio 'Console' window, run the code (provided below) to:a. Install packagesremotes anddevtools.b. InstallhyperSpec's dependencies.c. CreatehyperSpec's documentation.d. Install packagehyperSpec.

# Do not abort installation even if some packages are not availableSys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS="true")# Install packages remotes and devtoolsinstall.packages(c("remotes","devtools"))# Install hyperSpec's dependenciesremotes::install_deps(dependencies=TRUE)# Create hyperSpec's documentationdevtools::document()# Install package hyperSpecdevtools::install(build_vignettes=TRUE)
