Unfinished graph/plot in R Studio

Hi. I am trying to reproduce an article's simulations (this is the article: https://psyarxiv.com/km37w/), however some errors have been occouring, which I think I've been able to solve. Nevertheless, one of the final graphs is incomplete. It has the x and the y-axis, it has the legends and so on, but the lines do not appear. The printscreen of the R code and the graph is attached. Can someone please help? I've trying to solve this for a week.
Thank you in advance.

does it have the x axis ? it seems wrong; 1 , 3, 5 ... nothing else ...

You're right. In the meanwhile I figured out what else was wrong. Thank you for your help.
