Question

I have successfully put together 3three Histograms into 1one Plot with the Lattice package.
My data and code is as follows:

Puma_301 
   [1] 15  15  15  15  15  15  15  15  15  15  15  15  15  15  15  15  15  15

histogram(~Puma_303 + Puma_302 + Puma_301, type='count', layout=c(1,3), 
    main='Histograms of GPS points by Vegetation Types')

When I plot the 3three histograms at the very bottom of the plot appears the label

Puma_303 + Puma_302 + Puma_301

I have not been successful in finding a method to get rid of the bottom label.

Does anybody know how ‘histogram()’ can change the label into something else or not even show the label?

Thanks

p.s. I tried uploading the image of the plot but since I am a new user I am not allowed. sorry!!

Answer 1

This is an easy one, you just need ‘xlab’

histogram(~Puma_303 + Puma_302 + Puma_301, type=’count’, layout=c(1,3),main=’Histograms of GPS points by Vegetation Types’, xlab=”My xlab”)

Also, ‘ xlab= “” ‘ will remove the axis label altogether (have spaced that out for clarity).

Worked for me. Good luck.
