led_bulb.RdA function to standardize the random selection of bulbs for the LED project in BYUI's MATH 119.
led_bulb( number_bulbs = 1, seed = 9012017, dat = data4led::led_study, columns_keep = c("id", "hours", "intensity", "percent_intensity") )
| number_bulbs | The number of bulbs to sample. Defaults to 1. The most changed argument to the function. |
|---|---|
| seed | is used to make the random sample reproducible. May change at teacher request. |
| dat | is the data object from which the sample is taken. Defaults to led_study. |
| columns_keep | are the columns that should be returned from dat. Defaults to keep all the columns. |
