head(select(df, !column("x") > 0))

## End(Not run)
## Not run: 
df <- createDataFrame(data.frame(
  is_true = c(TRUE, FALSE, NA),
  flag = c(1, 0,  1)
))

head(select(df, not(df$is_true)))

# Explicit cast is required when working with numeric column
head(select(df, not(cast(df$flag, "boolean"))))
