My apologies, but I need your help an other once. Thanks for your help, and I hope I will understandable (I'm French PhD Student).
I give you my R code and I explain my problem :
plot(s9g$pupil_timestamp_secondes , s9g$diameter_3d_c , type='l' , xlab="Secondes" , ylab="Diamètre pupille (milimètres)" , col="royalblue3" , main="Premier regard sur les données \n pour ajuster datas aberrantes COUCHE DEBOUT - GAUCHE")
This first part is OK for me and it works. However, in my dataframe (y axes), I have missing value (NA).
My problem : When I have a missing value, my curve is cut (I try since yesterday to find differents possibilities to resolve my problem with "na.kalma" or others things but it doesn't works).
My aim : I want to connect/link these parts of my curve. And if it's possible with a specific color or with a dotted line.
Thank you for your help.
