I wish to use the devtools package. I've run the following commands:
> install.packages("devtools", dependencies = TRUE) .... > library(devtools) Error in library(devtools) : there is no package called ‘devtools’ What am I doing wrong?
Edit: Here are the results of re-running the install.packages command after restarting the session.

However, we recommend you install Rtools, so you can take full advantage of devtools. Soon, you will want to use devtools::install_github() to install R packages from GitHub, instead of CRAN. You will inevitably need to build a package that includes C/C++ code, which will require Rtools.
The aim of devtools is to make package development easier by providing R functions that simplify common tasks. An R package is actually quite simple. A package is a template or set of conventions that structures your code.
The devtools package contains functions that help with R package development. These functions include create , which creates the initial structure for a new package, as well as a number of functions for adding useful infrastructure to the package directory and functions to load and document the package.
As per damienfrancois's suggestion, I installed libcurl4-gnutls-dev and the problem was solved.
EDIT (@dardisco)
In your shell:
apt-get -y build-dep libcurl4-gnutls-dev apt-get -y install libcurl4-gnutls-dev If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
