• 9:00 PM - So long & thanks for all the fish.
Have RStudio downloaded and installed with the following packages:
• dplyr (might need to update the rcpp pacakge)
• ggvis (hosted on github)
# PACKAGE OF THE MONTH (PotM)
data.table - Fast aggregation of large data (e.g. 100GB in RAM), fast ordered joins, fast add/modify/delete of columns by group using no copies at all, list columns and a fast file reader (fread). Offers a natural and flexible syntax, for faster development.
# LIGHTNING TALKERS (5 - 10 mins)
Title: Statistical models of forest recovery indicate dynamic land use trade-off's ... we think.
Abstract: As background, Ill present my 3 minute thesis (Masters) then jump into the progress and hindrance of my attempt to model non-linear forest recovery. Were talking tweedie distributions (?), heteroscedasticity, known biologically-based hypotheses and other fun challenges.
Bio: Ira is from Vancouver, BC in his first year of his masters in Elena Bennetts's lab at McGill. His background is in forest ecology and conservation; not so much a statistician but he is stoked on R and here to learn.
Title: Reproducible analysis by writing package versions in R code.
Abstract: Since packages change so frequently, it is often difficult to reproduce old results. In this talk I introduce the works_with_R("3.0.2", changepoint="0.8") declaration which can be used to (1) record package versions, (2) install packages, and (3) warn if installed does not match recorded package versions.
Bio: Toby Dylan Hocking is a post-doc in the McGill Human genetics department who has been writing R code since 2003.
Title: Modeling woodland caribou space use in northern Quebec using R!
Abstract: An overview of some of the products I have developed to inform conservation planning for the woodland caribou, a threatened species in the boreal forest, including: a) deriving biological seasons from individual movement behaviour (rpart, REEMtree, zoo), b) estimating a weighted kernel density probability function for a population (KernSmooth, raster, maptools, rgdal), c) habitat selection modeling (spatstat, raster, survival), and d) spatial model prediction under different forest management planning scenarios.
Bio: I am a wildlife biologist/consultant conducting applied research and conservation planning for species-at-risk in the boreal forest. The favourite part of my job is writing R code to explore and analyze ecological data, and I am always seeking better and more efficient ways to do this. Some of my current goals include writing better functions, interfacing seamlessly with GRASS and multi-core processing. I am always stoked to interact with and learn from other R enthusiasts.
# MONTHLY SPEAKER (20 - 30 mins)
R at Strata, ggvis & dplyr
In this talk Ary will present an overview on R at the O'Reilly Strata Conference (California) and a quick hands-on workshop covering two new packages developed by Hadley Wickham (the man behind ggplot, plyr, lubridate & R Studio):
• ggvis for visualisation
• dplyr for data manipulation
Ary is Data Scientist at Radialpoint SafeCare Inc., co-organizer of the MTL R User Group and an R enthusiast.
