Dockerfile not working

[tensulin]

Great work on the package
The dockerfile failed to build for me, probably outdated

FROM jd21/olinkwrapper:v1.3.0 seems to be the correct base image now, while it is FROM jd21/shinyolink:latest there. Also it seems to be COPY inst/shiny/ /srv/shiny-server/ instead of COPY app/ /srv/shiny-server/ At least these changes worked for me for building.

Also an option for svg would be nice for plots, that is more like an improvement idea

Also the default selection SUBJID for "Match NPX & Var by:" crashes the app with the example data provided. Maybe change the default there or error handling for missing value
