My “twitter bubble” R analysis – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/04/20/my-twitter-bubble-r-analysis
Mainly things about R, Linux and vegetation modeling. My “twitter bubble” R analysis. April 20, 2016. April 20, 2016. I started using twitter on the INTECOL. After my last post on twitter friends and followers. I got curious, if I could find a way how to visualize the people/organizations I follow on twitter. I call this my “twitter bubble” according to the term “ filter bubble. For analyzing my twitter bubble, I use the R packages twitteR. Next, I set my twitter name and a rate limit of friend’s f...

https://joergsteinkamp.wordpress.com/author/joergsteinkamp
Mainly things about R, Linux and vegetation modeling. I am a Post-Doc at the Biodiversity and Climate Research Centre (BiK-F) in Frankfurt am Main/Germany. Currently I apply the dynamic global vegetation model LPJ-GUESS to model impacts of climate change, potential distribution of specific plant species, water usage, biome shift, and so on. My focus is on recent drought-induced mortality and carbon storage in forests and savannas. February 3, 2017. February 3, 2017. I’ve build an R package. July 14, 2016.

Twitter friends and (un-)followers with R – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/04/15/twitter-friends-and-un-followers-with-r
Mainly things about R, Linux and vegetation modeling. Twitter friends and (un-)followers with R. April 15, 2016. A few weeks ago the number of my twitter followers exceeded 100 and was going slightly down again and I was interested in who unfollowed me. Twitter does not offer that and I would have had to register at a third party page, which even wanted write access to my twitter account. I did not think about it for a while and then I found the R package twitteR. To make use of the twitteR. Library(twit...

Flying bumblebees – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/04/18/flying-bumblebees
Mainly things about R, Linux and vegetation modeling. April 18, 2016. April 18, 2016. Spring arrived and pollinators started their work. In 2013 I took a picture of a bumblebee, just leaving a flower and flying towards me by chance. If it was a sharp picture it would have been really great picture. Since then the same happened several times and in the following I show those photos, which are at least so (un-)sharp, that the insect can be recognized. Bees in the dirt. Leave a Reply Cancel reply.

Accelerate NetCDF-4 read access – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/07/14/accelerate-netcdf-4-read-access
Mainly things about R, Linux and vegetation modeling. Accelerate NetCDF-4 read access. July 14, 2016. July 15, 2016. For simulating the (global) terrestrial biosphere I need time series of climate data, which is mostly provided in a 3-dimesional NetCDF. The vegetation model I work with ( LPJ-GUESS. Commands to reorganize NetCDF-3 files. It first removes the unlimited time dimension and then permutes the dimensions, so that the data is ordered along the time axis. Next one needs at least 2*filesize RAM!

Mapping traceroutes with Perl – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/01/02/mapping-traceroutes-with-perl
Mainly things about R, Linux and vegetation modeling. Mapping traceroutes with Perl. January 2, 2016. January 11, 2016. I was playing around on my smartphone, looking for interesting apps and found one that displays the trace of a request to a server (e.g. www.google.com. Nevertheless, since I didn’t really need it, it was to expensive and I thought: “ok, let’s do it myself! 8221; and I wrote a little perl script and uploaded it to GitHub. As png or writes a GPX file. Which can be used in GIS-software.

Wasp variety in our community garden – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/01/22/wasp-variety-in-our-community-garden
Mainly things about R, Linux and vegetation modeling. Wasp variety in our community garden. January 22, 2016. May 20, 2016. Last summer I realized that there is quiet a variety of wasps is our community garden. And I know that not only bees are pollenizer, but I was not aware of wasps doing the same job. I took several pictures of them, of which I now publish the nicest here. UPDATED SPECIES NAMES (20.5.2016) Thanks to Alexandra Stevens (BUND Mainz). Who contacted an expert.

Broken axis with ggplot2 – Jörg Steinkamps Blog
https://joergsteinkamp.wordpress.com/2016/01/22/broken-axis-with-ggplot2
Mainly things about R, Linux and vegetation modeling. Broken axis with ggplot2. January 22, 2016. January 22, 2016. For visualizing my data I use R. And the library ggplot2. And just lately I made some sensitivity simulations with out dynamic global vegetation model (DGVM) LPJ-GUESS. The data used in this example can be downloaded from my Dropbox. Baseplot - function(data) {. P - ggplot(data, aes(x=value, y=name, col=sens). P - p theme bw(). P - p theme(legend.position="bottom"). P - p xlab(" ) ylab(" ).
