Y axis not long enough (Log scale)

Hi, I'm trying to get a visually pleasing Y axis

counts=c(Low = 3553, Mid = 203, High = 3158, Low = 13, Mid = NA, High = NA,Low = 16, Mid = 14, High = NA,Low = 1, Mid = 7, High = 21)
barplot(counts,log="y",ylab="Total counts from quadrats (Log scale)",axes=F)
axis(2, 0:4000)

enter image description here As you can tell from the results, things get a bit messy. And if I do axes=T, the axis just stops at 1000.

Solution

  • You can specify where you want the tick marks in axis. Also, change the ylim in barplot appropriately.

       counts=c(Low = 3553, Mid = 203, High = 3158, Low = 13, Mid = NA, 
        High = NA,Low = 16, Mid = 14, High = NA,Low = 1, Mid = 7, High = 21)

    barplot(counts,log="y",
            ylab="Total counts from quadrats (Log scale)",
            axes=F,
            ylim = c(1, 4096))

    axis(2, c(1, 8, 124, 4096))
