last-day, last-week or last-month (see details). If this is given, then from and to are ignored.

from

Start date, in yyyy-mm-dd format, or last-day. It is ignored if when is given.

End date, in yyyy-mm-dd format, or last-day. It is ignored if when is given.

Value

For packages a data frame with columns:

package

The package. This column is missing if all packages were queried.

date

Day of the downloads, it is a Date object.

count

For downloads of R, there are also columns for the operating system (os) and the R version (version).

Details

last-day is the last day for which data is available, last-week is from 6 days prior to that last day with data, last-month is from 29 days prior to that last day with data.

0 counts can be due to the non-availability of data on the RStudio server for that day.
