help on barplot
Hello, I am trying to compare two histograms using barplot. the idea is to plot the histograms as pairs of columns side by side for each x value. I was able to do it using barplot before but I can't remember now for the life of me now how I did it in the past:
d
[,1] [,2] -37.5 0.0000000000 2.789396e-05 -32.5 0.0001394700 5.578801e-05 -27.5 0.0019804742 1.732218e-02 -22.5 0.0217294282 1.380474e-01 -17.5 0.0938912134 4.005579e-02 -12.5 0.0630683403 4.351464e-03 -7.5 0.0163179916 8.368201e-05 -2.5 0.0025941423 5.578801e-05 2.5 0.0002789400 0.000000e+00 7.5 0.0000000000 0.000000e+00
barplot(d,beside=TRUE)
barplot here plots two separate 'sets' of columns, on the left side a bar plot of d[,1] is plotted while on the right side a separate bar plot of d[,2] is plotted. how can I combine the two? actually, while on the subject of histograms. is it possible to plot a 3D-histogram in R (a true 3D bar plot, without using image). many thanks Murad
