The names of the variables within the dataset as supplied to us may
not be in any particular form and may use different conventions. For
example, they may use a mix of upper and lower case letters
TempToday9AM) or be very long
Temperature_Recorded_Today_9am) or use sequential numbers
to identify each variable (
or use codes (
XVn34_rain) or any number of other
conventions. Often we prefer to simplify the variable names to ease
our processing and thinking and to enforce a standard and consistent
naming convention for ourselves.
We use base::names() to list the names of the variables within a dataset.
# Review the variables to consider normalising their names. names(ds)
##  "date" "location" "min_temp" "max_temp" ##  "rainfall" "evaporation" "sunshine" "wind_gust_dir" ##  "wind_gust_speed" "wind_dir_9am" "wind_dir_3pm" "wind_speed_9am" ##  "wind_speed_3pm" "humidity_9am" "humidity_3pm" "pressure_9am" ##  "pressure_3pm" "cloud_9am" "cloud_3pm" "temp_9am" ##  "temp_3pm" "rain_today" "risk_mm" "rain_tomorrow"
Notice that the names here use a scheme whereby the initial letter is capitalised and each word within the variable name is also capitalised. That’s a reasonable naming scheme and is preferred by some.
