Dear R-user,
I have read a dataset from .csv file into R. This dataset includes one
column containing some data in 'date and time' format, e.g. 'dd/mm/yyyy
hh:mm'.
These data were automatically read and saved as 'factor' in R. When I was
trying to produce some plots (such as time series) with the above 'date and
time' on x-axis, it caused some disodering problem, e.g. 1st of March 2012
is in front of 10th of Feb. 2012 (if the data is from 10th Feb. 2012 to 1st
of March 2012). I understand that I might have to convert them from
'factor' to 'date' first, so I tried using 'as.date'. But this method seems
only work for data in format of 'd/m/y' and no further option that allows
me to add hours and minutes.
I checked online for other methods such as 'as.POSIX' and 'strptime' but
none of them seem to offer me a quick solution.
Please note that the data I received is recorded every 10 minutes so they
are saved in the form of 'dd/mm/yyyy hh:mm', e.g. I only have data
measured up to 'minute' NOT to 'second'. Are there any direct solution
that I can solve this issue??
Many thanks in advance!
