Hi Tom,

a quick way to get R reports into DHIS will be to use Jason's approach to
get the R reports online (available at a URL) - then create a "Resource" in
DHIS 2 which points to the URL for each report.

To create a resource go to "Reports" - "Resource" and select "External URL"
under type. Give a descriptive name and set the URL to the R report.

You can now add those reports to the dashboard - in dashboard module set
"Resources" in one of the link areas to the left.
