Creating a small example

[smarou]

As suggested I created an input.csv file and I try to run it to receive the prediction.csv results but I receive this

$ sh requirements.sh

In addition: Warning message:

Any idea what I missed?

I'm unsure about the first part of you error as I don't use Windows for work. (That said if java is installed it doesn't matter.)

The second part says the following:
Warning in install.packages(c("caret"), dependencies = c("Imports", "Depends"), :
'lib = "C:/Program Files/R/R-3.5.2/library"' is not writable

Basically R can't install the packages needed for the classification task because your R library is not writable. One solution would be to run the requirement script as admin. If java is installed, you can simply skip the bash script and directly run requirements.R with admin rights.
