    I bit the bullet last night and did a do-release-upgrade to 20.04. Rebooted when all updates were finished and everything seems to be working and stable again. So I'm not sure what the configuration...

    I honestly don't know whether it happened after an upgrade. I've been keeping the system up to date this year by sshing into it from home. So there have been regular updates and use, but without...

    Re: Help with R, boxplot

    If you want multiple features in the legend, you need to specify them all in the call to legend. For example, in your legend you have two types of points, so you would specify them with

    Re: Help with R, boxplot

    R isn't finding your data file. Where is the "dores_05.txt" located? I can make this work using the following:

    read.table("dores_05.txt")->dores
    boxplot(h~srtm,data=dores)
