Subsetting data by date
...eel it will stand me in
better stead in the long run.
Currently the dates are in the form
1-Apr-1997,
3-Sept-2001,
etc.
I will create a data.frame with date as one of the variables, the
others being (initially) temperature, humidity, and Admissions (the
number of hospital admissions for COPD exaserbations).
Please could somebody tell me if there is a simple way to extract the
data I want, and if so perhaps a sample command to get me going? Do I
first need to format the dates to some numeric-only format? As I say, I
could use Excel to create the files in the right format, but I will be
dealing wit...
