  2. Deprecared

    Hi there!

    I am learning Data Science form your wonderful academy, your magnificent videos and you amazing technology. Sincerely I do not have enough words to say thank you, because of this, I am trying to reach a new job on this great new world of Data Science.

    Well, the thing is that I am very happy that for once in life, all software and everything needed I do not have to install it and this is great.

    Because of this I need to ask you guys for a couple of little errors when I try to replicate the exercises…

  6. rJava package issue

    Recently i am unable to use the RWeka package in RStudio. It is because its related package rJava is not installing properly. This has happened quite recently. I investigated a bit and doubt if it has to do with mismatch of java versions in R and the JDK. Is it possible to update the Java with latest JDK 9? If you have any other solution in place, please let me know. At the moment, i am unable to use any package that has rJava package dependency. Appreciate your help in this

  13. Error installing Rstan

    I am trying to install "rstan" package from within rstudio. I got the error message saying "/usr/bin/ld: cannot find -lgfortran
    collect2: error: ld returned 1 exit status ..."

    This is probably because I do not have gfortran and its libraries installed. I know how to do this on my local Linux machine but don't know how to do it with the DSW cloud environment.

    Thanks.

    Best,
    Shige
