I want to make a legend title reading
CO₂-text1
text2
Since paste()
/paste0()
doesn't seem to work on expression I also tried using bquote()
instead, but can't figure a way to add the new line. My most succesfull attempt so far:
expression("CO"[2]*"-text1 \n"*" text2")
, which results in
-text1
CO₂ text2
