I conducted a frequency averaging procedure which left me with the data frame below (Bin is an artifact of a cut() procedure and can be either as.character or as.factor):
Bin Freq 1 (-180,-160] 7.904032 2 (-160,-140] 5.547901 3 (-140,-120] 4.522542 4 (-120,-100] 4.784184 5 (-100,-80] 4.490083 6 (-80,-60] 4.754268 7 (-60,-40] 5.597407 8 (-40,-20] 5.964031 9 (-20,0] 7.266519 10 (0,20] 6.947202 11 (20,40] 6.168730 12 (40,60] 4.918232 13 (60,80] 4.638589 14 (80,100] 4.288087 15 (100,120] 4.091052 16 (120,140] 4.451199 17 (140,160] 5.869740 18 (160,180] 7.796204 I am able to present the data as a histogram using barplot(), but on the x-axis I would like to see the values that separate (i.e. that are located between) my various bins (i.e. seq(-180,180,20)). Thus 0 would appear directly under the centre line that separates (-20,0] and (0,20], etc. barplot(angledist$Freq, xlab="Turning Angle", ylab="Average frequency (%)", ylim=c(0,10)) ?names.arg, ?xlim don't seem to do it but I could be wrong....
