Like this?
plot(Y~X, log="y")
Hope this helps,

Thank you,
but why it does not work in linear? With the log scale, I know it
works but I am not looking for it; is there a way to force a linear
scale?
Regards
Luigi

Hello,
I have these vectors:
```
X <- 1:7
Y <- c(1438443863, 3910100650, 10628760108, 28891979048, 78536576706,
213484643920, 580311678200)
plot(Y~X)
```
The y-axis starts at 0e0, but the first value is 1.4 billion. Why the
axis does not start at 1e9?
Because you're plotting on a linear, not log, scale, and 0*10^11 = 0.
round(Y/1e11)
[1] 0 0 0 0 1 2 6
Then try plot(log(Y) ~ X).
I hope this helps,
John
