Installation requirements and instructions

Requirements

Most recent versions of the following software are always preferred, however the minimal requirements are also specified. The common software required by three main-stream operative systems are provided below, and any specific requirement is treated separately:

• R software: the minimal requirement is R version 3.5.1.

• R packages (it is recommended if the most recent versions of the following packages are installed):

  • Rcpp, for interfacing C++ code with R;
  • RcppArmadillo, for interfacing C++ algorithms for linear algebra with R;
  • devtools, for developing utilities and interfaces with on-line repositories;

To install the required packages, the following R code should be exectued before the installation:

pkgnames <- c("Rcpp", "RcppArmadillo", "devtools")
pkgnames <- pkgnames[!pkgnames %in% .packages(TRUE)]
if (length(pkgnames)) install.packages(pkgnames)

To update all the installed packages to the last version available, the following command line should be typed into an R console:

update.packages(ask = FALSE)

The additional software must be installed before to update the required packages.

Additional software on Linux

• GNU compilers: the minimal requirement is gcc version 4.9.3.

Additional software on Windows

• Rtools is a library which provides the GNU compilers. The minimal requirement is Rtools33.exe, or other versions according to the R version already installed. Successively, the environmental variable PATH must be edited, because it must include the folders containing the GNU compilers provided.

Additional software on (Mac) OS X

• X-code is required to install the GNU compilers. The minimal requirement is gcc version 4.9.3, which allows for C++11 syntax.

Package management

Installing the stable release of the inca package

The use of the following R command is highly suggested to install the inca package:

install.packages("inca")

The other alternative to install an R package is from its source-code compressed as a tarball archive. This can be done by entering the following command into a terminal session on Linux and (Mac) OS X :

R CMD INSTALL inca_0.0.4.tar.gz

On Windows, by opening the command prompt (cmd.exe), it is possible to point to the proper directory with cd, and then install the package via Rcmd.exe with the following command:

Rcmd.exe INSTALL inca_0.0.4.tar.gz

More details can be found on the "Installing packages" section of the R-admin manual.

Installing the current development version of the package

devtools::install_github("drwolf85/inca")

Updating the inca package

To update the inca package, it is necessary to type the following code from the R console:

update.packages("inca")

Removing the inca package

To remove inca from the list of R packages, it is necessary to type the following code from the R console:

remove.packages("inca")
