# What can we do with a single survey?

August 04, 2015

We presented a poster at the ICCB/ECCB 2015 congress in Montpellier, France, that summarized our research on single visit methodology.

We showed that if information on habitat covariates that affect occupancy/abundance and detection are collected, then one can estimate detection probability as well as occupancy/abundance parameters.

Check out the reprints and the poster made with Scribus:

Organizers wanted the poster sessions to be interactive. But posters are hung up much longer than the actual poster session. What can be done to make posters interactive in the absence of a presenter? This gave the idea to mimic a blog post, both in style and in structure. I added space for comments and created a mini poll, left out a marker on a string, and waited for the results.

Survey responses were mostly positive, which is good. But the best of all was a cute little girl who was thrilled at the notion of drawing onto the poster. Thanks for the feedback!

#### What is new in the intrval R package?

An update (v 0.1-1) of the intrval package was recently published on CRAN. The package simplifies interval related logical operations (read more about the motivation in this post). So what is new in this version? Some of the inconsistencies in the 1st CRAN release have been cleaned up, and I have been pushed hard (see GitHub issue to implement all the 16 interval-to-interval operators. These operators define the open/closed nature of the lower/upper limits of the intervals on the left and right hand side of the o in the middle as in c(a1, b1) %[]o[]% c(a2, b2).
