Question

I have a data.frame (df) with a date column Date (dd-mm-yyyy).
How do I convert it to just (mm-yyyy)?

I have tried:

dates <- as.Date(df$Date, "%m/%Y")

but this did not work. I would be greatful for your help.

Answer 1

Technically, "mm-yyyy" is not a date. If you just want a value for printing/plotting, just format the Date column via format(df$Date, "%m-%Y"). If you want to use the result as a measure of time, use zoo::as.yearmon.
