I'm having trouble getting the axis labels to fit properly on my facetted radial plots. I can't really

I use the coord_radar function to create straight lines around the radial plot:

  function(theta='x', start=0, direction=1){
    # input parameter sanity check
    match.arg(theta, c('x','y'))

    ggproto(
      NULL, CoordPolar, 
      theta=theta, r=ifelse(theta=='x','y','x'),
      start=start, direction=sign(direction),
      is_linear=function() TRUE)
  }

Then here's my graph:

ggplot(VGR.mpre, aes(y=value, x=variable.2, group=factor(X), colour=Impaired.Task.Score))+
  geom_polygon(fill = NA)+
  geom_path(aes(group=factor(X)))+
  geom_point()+
  coord_radar()+
  labs(x="Parameters", y="Z-score", title="Pre-op parameters for Visually Guided Reaching Task")+
  scale_colour_manual(name="Impaired (Task Score > 1.96)", labels=c("No", "Yes"), values=c("#619CFF", "#F8766D"))+
  theme(axis.text.x = element_text(face = VGR.mpre$face))+
  facet_wrap(.~factor(X), nrow=2)+
  theme_bw(base_size=25)+
  theme(legend.position="bottom", legend.box="horizontal")

When I export the image, some of the axis labels are always cut off. This is a screenshot of the graph. "No Movement end" for example is cut off. I've tried using white space \n for the labels which worked for some of them, but I'm really wondering if there's a function that adjusts the amount of space between the panel borders and the graph itself. I can't seem to find the answer anywhere else on stack overflow, but if someone could link me to a similar question and/or help me out that would be super appreciated!!

    check out https://stackoverflow.com/questions/22945651/how-to-remove-space-between-axis-area-plot-in-ggplot2 and "Related" tab on the side. – Dylan_Gomes Nov 11 '20 at 19:34
  • @Dylan_Gomes Thanks! I noticed a few of those related posts. I'm wondering which one you are referring to? And is there anything of note for radial plots? – Jssemrau Nov 12 '20 at 17:18
  • Because the vjust and hjust don't seem to work for radial plots. I've tried the margins, but I don't see them making any difference in radial plots either :/ – Jssemrau Nov 12 '20 at 17:51
