r - How to sort a data frame by date

Question

I need to sort a data frame by date in R. The dates are all in the form of "dd/mm/yyyy". The dates are in the 3rd column. The column header is V3. I have seen how to sort a data frame by column and I have seen how to convert the string into a date value. I can't combine the two in order to sort the data frame by date.

Answer 1

Assuming your data frame is named d,

d[order(as.Date(d$V3, format="%d/%m/%Y")),]

Read my blog post, Sorting a data frame by the contents of a column, if that doesn't make sense.
