title: How to change the scales on the x axis in the Histogram made using Lattice package in R?
body: <p>I have been successful in making the Histogram for the variable wind speed for all years and months in my data set. But I want the the x-axis labeled at 1 mile/hr intervals.Each bin is also of 1 mile/hr interval. Currently by default the x axis is labeled at 20 miles/hour intervals. </p>
  
  <p>Here is my R code.</p>
  
  <pre><code>histogram(~ as.numeric(spd) | factor(month) + factor(year), data = spd_sub, 
    xlab = "spd in miles/hour", 
    nint= max(as.numeric(spd))-min(as.numeric(spd)), layout = c(1, 1))
  </code></pre>
  
  <p>Any idea how to do this? </p>
