[R] help on ploting various lines

[Neuro LeSuperHéros]

Hi.  set a ylim equal to the max of your data:

#create test data
x1 <- x2 <-x3 <-(1:10)
y1 <-runif(10)/2 #to get a low maximum y1
y2 <-runif(10)
y3 <-runif(10)

#plot as you did
plot(x=x1,y=y1,type="l") #y-axis is not big enough
lines(x=x2,y=y2)
lines(x=x3,y=y3)

#plot with minimum/maximum y limit
plot(x=x1,y=y1,type="l",ylim=c(min(y1,y2,y2),max(y1,y2,y2))) #fixed
lines(x=x2,y=y2)
lines(x=x3,y=y3)
