I am hoping for some advice regarding ordering a dataframe, by date.
The dataframe is in the format below.
$story $datepub
story10 1 April 1999
story 90 1 March 2002
story 37 10 July 1985
I want to reorder the entire dataframe so the earliest story is first, and
save the reordered dataframe. The command, 'class' (datepub) reveals
$datepub is a factor variable.
I tried the following:
d2 <- as.character(datepub)
rank(d2)
Any assistance is appreciated,
regards
Bob Green
