For the (Advanced) R Crash Course of the Data Science for Actuaries program, we will use the Ubuntu virtual machine. There might be some issues when installing some packages... One trick can be to open a terminaland then to use the sudo command, to install some packages,(after entering the password). Just type (or copy/paste)sudo apt-get install libcurl4-openssl-devsudo apt-get install libxml2-devsudo apt-get install openjdk-8-*update-alternatives --config javasudo apt-get install aptitudesudo aptitude install libgdal-devsudo aptitude install libproj-devsudo apt-get install build-essential libcurl4-gnutls-dev libxml2-dev libssl-devsudo apt-get install curlsudo apt-get build-dep r-cran-rglsudo apt-get install r-cran-plyr r-cran-xml r-cran-reshape r-cran-reshape2 r-cran-rmysqlsudo apt-get install r-cran-rjavasudo apt-get install r-cran-glmnetsudo apt-get build-dep r-cran-bootsudo apt-get build-dep r-cran-classsudo apt-get build-dep r-cran-clustersudo apt-get build-dep r-cran-codetoolssudo apt-get build-dep r-cran-foreignsudo apt-get build-dep r-cran-kernsmoothsudo apt-get build-dep r-cran-latticesudo apt-get build-dep r-cran-masssudo apt-get build-dep r-cran-matrixsudo apt-get build-dep r-cran-mgcvsudo apt-get build-dep r-cran-nlmesudo apt-get build-dep r-cran-nnetsudo apt-get build-dep r-cran-rpartsudo apt-get build-dep r-cran-spatialsudo apt-get build-dep r-cran-survivalsudo apt-get build-dep r-cran-rodbcsudo apt-get build-dep Then, in RStudio, enterinstall.packages("RCurl")install.packages("xml")install.packages("rJava")install.packages("rgdal")install.packages("xlsx")install.packages("devtools")It should be fine...
