show 0 in a log scale y axis of plot in R

Question

Because the y values are too small, I need to use a log scale for y axis to show the differences. In the data, some entries do not have any value (0). Is there any way to show \

Answer 1

Choose some minimum value, and use that to represent 0:

m <- min(y[y!=0])/10
plot(x, pmax(y, m), log="y")
