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

?DateTimeClasses

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.
