This was a change in tidyr 0.7.0 that is causing a lot of confusion,
so we are preparing tidyr 0.7.1 which will back this change out.
If you want a work around in the meantime, you can express your
operation a bit more elegantly as:
library(tidyr)
df <- data.frame(v1 = 1:5, somestring = 6:10, v3 = 11:15, v4 = 16:20)
df %>%
gather(key = var, value = val, somestring:ncol(df)) %>%
head(2)
