Ignore SSL when installing packages in R - r

When I try to install a package like this: install.packages("RGtk2")
I get the following error:
Warning in install.packages :
package ‘RGtk2’ is not available (for R version 3.3.2)
Warning in install.packages :
URL 'https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.3/PACKAGES.gz': status was 'SSL connect error'
Warning in install.packages :
URL 'https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.3/PACKAGES': status was 'SSL connect error'
Warning in install.packages :
unable to access index for repository https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.3:
cannot download all files
How can I disable SSL so that my install goes through? I know that normally this would be bad from a security standpoint, but in this case I'm pretty sure that SSL error happens because there is some corporate proxy server that alters a certificate in some way.

Package install problems

Attempting to install packages from the office today, I'm getting:

I have UNTICKED "Use secure download" (as you can see), and there is NO .Renviron or .Rprofiles that change the repos.
From the browser I am able to open http://cran.rstudio.com/bin/windows/contrib/4.2/PACKAGES without any problem.
I've seen many posts like this, but none where the site is working ok in the browser. Is this likely to be a corporate firewall issue or something set incorrectly in my rstudio settings?

I have a problem to install package 'swirl' on my Rstudio. I tried several cran in China and it cannot connect to server every time. Does anyone know any possible reason? *ps:since the stackoverflow does not allow me to post more than one URL link so I cut off a 'h' of from 'http'

R - cannot access urls for package installation

I recently installed R Studio (Version 0.99.892) on a personal computer (windows 8) and am trying to install, among others, the following packages:
ggplot2;
dplyr;
rmarkdown;
tidyr.
Neither R nor R Studio is able to install any of these packages. Each time I attempt to install a package, I get the set of warnings I include at the bottom of this post.
I have used the install.packages command as well as the built-in package installation tool. I have tried several different mirrors.
I have tried a public university internet source, my own private internet source, and a phone tether. I have tried to connect through a VPN. I have added R Studio to my Windows Firewall exception list and have also completely disabled the Windows Firewall. I am running no other firewalls.
I have toggled the various connection options in the "Packages" tab in Global Options.
I can access the URLs in a browser.
Here are the warnings from R Studio:

There are several stackexchange posts on package installation in R and R Studio, but I was not able to find any that answered my particular situation. Thanks in advance to anyone that knows what's going on

Run this command:
options(repos="https://CRAN.R-project.org")
after that try install.packages;it should work.Tested on my system.

This has happened to me before. Try explicitly specifying the location:
install.packages("devtools", repos="https://cran.rstudio.com/")

You can indeed specify the location when using the install.packages() function with the argument repos=, but you can also choose your favorite repository which will be used each time you download a package.
options(repos="my_favorite_CRAN_mirror")
You can see a list of all availables mirrors on the CRAN website. Juste copy/paste the adress of the closest CRAN repository to you.
You should be able after this step to retry install.packages('ggplot2')

You should try following code:
install.packages("ggbiplot",dependencies = TRUE, repos = 'http://cran.rstudio.com/')
It will help you to install the packages for the error:
package is not available for this version

Run the following command in R terminal-
options(repos="https://CRAN.R-project.org")
then-
use-install.packages('library')

I want to add that I had this issue, but the fix was not in R, but in our system. Our IT guy said: For some unknown reason, the DNS resolver service was unable to resolve hostnames. I’ve restarted the resolvd service. The server can now resolve hostnames.
The error on his end was: Temporary failure in name resolution

I was having a similar error while trying to install the packages dplyr, tidyr packages.
I solved the issue by checking my R.version and downloading a new version of base R. (3.3.3)

Try this...
Tools-->Global Option--> Package
Change "Primary CRAN Repository" to htpps Location
This method fixed my issue

Dependency error in installing packages in R

Hi I am relatively new user of R. Installed R on win8. Now I am trying to install packages but i getting following error:
install.packages("C:/Users/Owner/Downloads/pROC_1.5.4.tar.gz", repos = NULL, type = "source")
Warning in install.packages :

Warning in install.packages :

Installing the plyr package won't make a lot of difference since pROC is not supported for your R distribution.
Also since you use Rstudio you might find it easier to install packages via
Tools>Install Packages
and then set
Install from:
to
Repository(CRAN).
That way you don't have to manually download them.
As an alternative to pROC you can maybe use ROCR.
Also this might be of interest if you were planning to use pROC to calculate the area under the curve, anyway I'm digressing.

it would appear that the immediate problem is the fact that you are using forward slashes instead of backslashes, were you to change that it would look like this:
install.packages("C:\\Users\\Owner\\Downloads\\pROC_1.5.4.tar.gz", repos = NULL, type = "source")
Good luck!
