A helpful note
Saving text elements via the default svg-drivers of R (e.g., grDevices::svg, Cairo::CairoSVG) often results in the text being saved as paths instead of genuine text elements. Downstream svg-editors (such as Inkscape) may thus only allow you to move single letters but not edit them as text elements (which slashes the point of being a text element).
Fortunately, the R package svglite contains an svg-driver that saves text elements as such.
