I am currently trying to install the gganimate package but seem unable to.
I am running Win 10, Rx64 3.3.0 and Rstudio 0.99.896;
the following command:

```
devtools::install_github("dgrtwo/gganimate")

```

will throw this error:

```
Downloading GitHub repo dgrtwo/gganimate@master
from URL https://api.github.com/repos/dgrtwo/gganimate/zipball/master
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Problem with the SSL CA cert (path? access rights?)

```

So after a few hours of despair, I decided to try and install the package manually. I followed this link:
[here](https://stackoverflow.com/questions/14806705/manually-downloading-and-installing-packages-in-r?lq=1)

the following command:

```
install.packages(pkgs = "C:/Users/Superzucca/Desktop/gganimate-master.zip", repos = NULL)

```

results in:

```
    Installing package into ‘C:/Users/Superzucca/Documents/R/win-library/3.3’ 
(as ‘lib’ is unspecified)

```

but then when I call:

```
library("gganimate-master") ####  -> as suggsted by R itself!! 

```

this error is thrown:

```
Error in library("gganimate-master") : there is no package called ‘gganimate-master’

```

please, help. I don't have any problems installing other pkgs and honestly don't know what else to try.
Thank you in advance,
Superzucca
