[R] Question about setting tick mark limits in Plot

I am having trouble getting the Plot function to set the tick marks the
way I want, and I am not sure what I am doing wrong.
Below is the code that I wrote, and I am not sure why it doesn't work.
p is a vector of length 2198, containing numbers between 0 and 240. q
is a vector of ones, the same length as p. I want the x-axis to have
tick marks every 30 min and I want the last tick mark to be at 240 min.
When I run the program it only plots 5 tick marks starting at 0 and
ending at 200, though the data extend to 240 min. I am very confused.
Thanks for any help. I really appreciate it. I have wasted too much
time trying to figure this out on my own.
plot(p,q, pch="|", yaxt="n", main=subject,xlab="Minutes", ylab="")
