[R] x[0]: Can '0' be made an allowed index in R?

[Ebert,Timothy Aaron]

You could have negative indices. There are two ways to do this.
1) provide a large offset.
Offset <- 30
for (i in -29 to 120) { print(df[i+Offset])}


2) use absolute values if all indices are negative.
for (i in -200 to -1) {print(df[abs(i)])}

Heh. Did anyone bring up negative indices yet?
