ii. Fix Data Quality Issues
- Change File ID from numeric to character
- Change coordinates to numeric
- Change Date from Character to Date
- Omit the two NA values for the Y coordinate.
- Clean the Dates (All standardise to m/d/y. For missing month/year, I will replace with NA. For missing day, I will impute as 1st day of the month.)
- Clean the Timing (Standardise all to 24 hour formatting. Use “.” instead of ":")
- Clean the Vocalisation Type (Standardise all to lower case. For values consisting of both ‘song and call’, change to ‘call’, assumed as a sign of distress while ‘song’ is assumed as the default)
- Clean the Quality (Recode ‘no score’ as ‘NA’)
iii. Data Manipulation
- Extract out the “Year” and “Month” from the date, as new columns
- Create a new column for Quarter (Q1,Q2,Q3,Q4) & Season (Spring, Summer, Fall, Winter)
