Pre-process your data into per-day or per-month records, then plot it. There are many ways to do this... for example, base R has the aggregate function, and the dplyr package has the group_by/summarise functions, and the data.table package can do this as well (read the vignettes).
All of these techniques require that you learn how to deal with timestamps using one or more of the time classes. The most common of these can be introduced by reading
and/or reading some of the fine blogs online regarding this topic. Note that the trunc.POSIXt function offers one way to identify which time interval each record of your data belongs to.
If you need more assistance, read the Posting Guide and create a reproducible example similar to the data you are working with, and be sure to post it using plain text so it does not get corrupted in the mailing list.
