Accessing Raw Data from a Server for Analysis in R

Analysis and Data
1

Hello,

My name is Josh and I’m a graduate student working with Dr. Lawrence Niles regarding Red Knots in the Delaware Bay. I have obtained MOTUS scripts to work with data, but I do not have any raw data from the tags to plug into R? From reading the MOTUS script it seems I can retrieve this data from a server…?

“Next, we load the Motus telemetry data from the server using the ‘tags’ function from the sensorgnome package. At present you must have access to the server on Discovery (discovery.acadiau.ca) to use this function. In the future, these queries will be contained within the Motus database.”

When I click on the link “discovery.acadiau.ca” I do not see anywhere where I can access a server to obtain the raw data to plug into R. Any help would be appreciated. This question may not be in-line with other posted sensorgnome questions, but I figured I would start here to find an answer.

Thank you,

Joshua Barth (M.S.c)

Ever have any luck with this?

I too am interested in obtaining a ‘raw’ dataset, before the filtering for run lengths occurs.

Hi Dylan, if you’re downloading your data with the R Package, you’ll always have access to all of the data regardless of run length. Short runs which have been flagged and filtered out on the website are still present, but will be indicated that they had been flagged.

The documentation for the R Package is here, and it contains some specific chapters related to filtering and cleaning data. This is a pretty important step since both the automated run length filtering, as well as some of the manual filtering, will occasionally remove valid detections. There is a bit more about the filtering here and here.
