Working under WIN10-64, I have updated R from 3.5.1 to 3.6.2, RStudio from 1.2.1335 to 1.2.5033 and ggplot2 from 3.0.0 to 3.2.1. Since then, a graphics function which worked flawlessly so far, shows all expected geom_lines, geom_labels and axis labs, but completely lacks all geom_text annotations. These annotations invariably have a structure as shown:
...ggplot()+ geom_line() ...+ # several elements - working correctly´ ´... geom_label()...+ # several elements - working correctly´ ´...geom_text(aes(x=min(xB), y=ymax+0.1*ysp, ´ ´label=("short text elements")),´ ´size=3.0, color=1, hjust="left") +... ´# several annotations - not showing up´
The "short text elements" are string variables or strings concatenated with numeric variables using paste0().
I am unable to find any reason for this change. An attempt to downgrade ggplot2 back to version 3.0.0 was unsuccessful: again, the text annotations did not show up. There is no error message whatsoever. The R-program itself, which produces the necessary data and within which the graphics function is called, is working correctly as usual.
I would be very grateful to receive any possibly helpful hint to solve this problem.
Thanks in advance,
Leo
