Installing AWS S3 R package - r

Question

I am trying to install the S3 package on R inorder to save csv output on regressions I am running. I tried to install the S3 package to link the Rstudio server to S3 but with no luck. This is the error I recieved when trying to install the aws.s3 package:
> install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))

I then tried installing the httr depence package but with no success as well.

Using PKG_CFLAGS=
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because openssl was not found. Try installing:
* deb: libssl-dev (Debian, Ubuntu, etc)
* rpm: openssl-devel (Fedora, CentOS, RHEL)
* csw: libssl_dev (Solaris)
* brew: openssl#1.1 (Mac OSX)
If openssl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a openssl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Likewise when installing the openssl package. My EC2 instance type is a t2.medium.

Answer 1

Here, both some OS and some R dependencies are needed before installing the aws.s3 package of cloudyr.
aws.s3 depends on three R packages: curl, httr and xml. These depend, in turn, on the libssl, libxml2 and libcurl4-openssl OS libraries.
On a fresh new EC2 instance, assuming a Ubuntu box (but of course there are the equivalent yum packages for Fedora/CentOS/RedHat distros), OS dependences have to be installed for first:
sudo apt-get install -y build-essential libssl-dev libxml2-dev libcurl4-openssl-dev
Then you can install the following R packages, in the specified order:
install.packages('curl')
install.packages('httr')
install.packages('xml2')
install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))
Hope this helps
