r - trouble in installing rgdal on ubuntu 16.04

Question

I have been trying to install rgdal on R 3.4.2 (RStudio 1.1.383) and ubuntu 16.04 but it always end with a problem.

I have followed many recommendations like manually installing the dependencies like libproj-dev or my last try by using homebrew.

I was able to install gdal 1.11.3 but it's not sufficient.

Here is the output when I write

    install.packages('rgdal', type = "source", configure.args=c('--with-proj-include=/usr/local/include','--with-proj-lib=/usr/local/lib'))

Installing package into ‘/home/tupac/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)

The error "proj_api.h not found" has also been found in the same post but the solution given does not work in my case while it seems to work for many other users.

thank you for helping me in fixing this problem.
