I don't do "why" answers. Only how. Occasionally.

?plot.default ##with the axes=FALSE argument. Then

?axis ## note the labels and at arguments.

Subject: [R] Why does plot() ignore the data type for axis labels?

Hello,

I was wondering why the plot() command ignores the datatype when displaying axis labels. More specifically, if the data points are integers then the axis labels should intuitively also be integers, right?

> x <- as.integer(c(1,2,3))
> y <-x
> typeof(x)
[1] "integer"
> plot(x,y)
>

The axis labels are 1.0, 1.5, 2.0, 2.5, 3.0 but if the integer type were taken into account they would be 1, 2, 3.

PS what's the right way to get integer labels? Z.
