Processing sub-bottom profiling data in Python

by on November 17, 2016

In addition to processing bathymetric data, my research on lakes requires sub-bottom profiling, or the collection of low-energy seismic data collected similarly to bathymetric data. The system we use is the SyQwest HydroBox, which, due to many hardware and software limitations, has been particularly frustrating. Still, when it does work properly, the HydroBox data has […]

apply() yourself in R

by on November 14, 2016

A few months ago I wrote what I thought was a quite useful post on list comprehensions in R, which, after working with numerous datasets since, I have realized is almost useless. In the post, I suggested a few ways to go about generating vectors of data using non-vectorized functions. Packages such as foreach, plyr, […]

Canada Weather 2.0

by on November 13, 2016

I’m happy to announce that after a week-long struggle with the intricacies of the Android AppWidget framework, I’ve just released a new version of Canada Weather. Over the past year requests have piled up involving more flexibility for the widget, better use of space on the widget, antiquated user interface, no option for sound on […]

New article!

by on November 3, 2016

It’s been a nearly 9-month saga, but I’m pleased to announce that my first ever peer-reviewed paper has been published in the Journal of Paleolimnology as of October 2016. The paper (“A geochemical perspective on the impact of development at Alta Lake, British Columbia, Canada“) is a result of my M.Sc. work on Alta Lake […]

Holes in ggplot polygons

by on July 13, 2016

As part of my efforts to construct an R package connecting ggplot and Spatial objects, I came across an issue with ggplot involving holes in polygons. According to the collective knowledge of StackOverflow, it’s possible to make this happen by putting the coordinates in the correct clockwise/counterclockwise order, extending geom_polygon() somehow, or other really complicated […]

Spatial data in ggplot2

by on July 12, 2016

I recently figured out how to use the ggplot2 framework to plot raster data, which led me to write a package extending ggplot2 for more convenient spatial data geometries. Ever wanted a geom_spatial() for those SpatialPolygonsDataFrames and RasterBricks you’ve got kicking around? Well…maybe you did or didn’t, but the ggspatial package is now here for […]

Mapping R Package Updates

by on April 12, 2016

The past few months haven’t been particularly productive on the R package front (I’ve mostly been using R for plotting lakes data), but small updates here and there have led to a bunch of exciting new features in the prettymapr, rosm, and rcanvec packages. Things like geocoding, finding a bounding box containing multiple queries, exporting […]
