Character Variable in X axis scatter plot
2 messages · John Jeffery, David L Carlson
Function strptime() will convert the date-time character string to a POSIXct
object that you can use in your plot. In general, when posting a query to
r-help:
1. Do not use html, only plain text (see what happened to
your data below.
2. Use dput() to convert your data to a format that is easy
to import from an email message.
