Plot one numeric variable against n numeric variables in n plots

Question

I have a huge data frame and I would like to make some plots to get an idea of the associations among different variables. I cannot use

pairs(data)
<         


        

Answer 1

The package tidyr helps doing this efficiently. please refer here for more options

data %>%
  gather(-y_value, key = "some_var_name", value = "some_value_name") %>%
  ggplot(aes(x = some_value_name, y = y_value)) +
    geom_point() +
    facet_wrap(~ some_var_name, scales = "free")

you would get something like this
