Note If you already have R installed in the machine you may see Microsoft R link is not created and previous R is still available at /usr/bin/R. If that is the case you may need to create the symbolic link as below.
Creating symbolic link:
$ sudo ln -s /usr/lib64/microsoft-r/3.3/lib64/R/bin/R /usr/bin/MSR
Launching R:
You just need to do the following:
$ R
If you have created the symbolic link then use the following
$ MSR
Installing RCurl which is must to have for H2O:
> install.packages(“RCurl”)
Now installing H2O latest from the H2O Download link (https://www.h2o.ai/download/)
> install.packages(“h2o”, type = “source”, repos = (c(“http://h2o-release.s3.amazonaws.com/h2o/rel-ueno/5/R”))) :
Once H2O is installed you can use it. Here is the full execution log:
