Binomial into binary

[Santiak]

As always, this is likely just one possible solution:

df$v <- as.numeric(as.character(factor(df$v, c("name1", "name2"), labels = c(1, 0))))

"df" is the name of your dataframe
"v" is the name of the variable containing the values you want to turn into binary.

---

Alternatively, you can use:

df$v <- as.numeric(df$v)-1

Just be aware that it doesn't discriminate correct from incorrect, but assigns the value based on when the value appeared, so if you used a randomized paradigm, you might end up with some vectors having their "correct" listed as 1, but "incorrect" as 1 in others.

---

If all else fails, you can manually correct your dataframe by doing:

fix(df)

Which will bring up a small window where you can replace the values directly.
