I don't see any problem with the code in your image. If you meant to post a video, it didn't work. Please describe your problem.

I typed in these codes yesterday and it replied like this（> a <- c(1900:2019)

b <-seq(from=1,to=50,by=2)
plot(a,b)
错误于xy.coords(x, y, xlabel, ylabel, log): 'x'和'y'的长度不一样）
But today I tried it again and it worked, I don't know what the problem is
