Warning: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0.
ℹ Please use `linewidth` instead.
ℹ The deprecated feature was likely used in the cylcop package.
  Please report the issue at <https://github.com/r-lib/devtools/issues>.
Error in `geom_label()`:
! Problem while setting up geom aesthetics.
ℹ Error occurred in the 4th layer.
Caused by error in `list_sizes()`:
! `x$label` must be a vector, not an expression vector.
