Create integers by default if all values are integer-valued

I am wondering what the reason is why R creates doubles by default even if all values are integer-valued.

``` r
typeof(1)
#> [1] "double"
```

One reason I can think of is that doubles are 64 bit, while integers are 32 bit by default, so creating doubles allows for a greater range of values.
