Feed: Cloudwards. Author: Elsie Otachi; Editing a .pdf can be tricky. Though it’s a great way to quickly compile and publish information, it isn’t a file format you can edit out of the box. Unlike a Microsoft Office document, a .pdf in’t designed for editing, which is why you need the right tools to tweak the content. A quick search on the internet will show you many editing options for .pdf documents. Some are quite expensive, but the cheap or free editors only offer basic features and don’t convert files accurately. Many can’t edit the text or graphics in a ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. The grainchanger package provides functionality for data aggregation to a coarser resolution via moving-window or direct methods. Why do we need new methods for data aggregation? As landscape ecologists and macroecologists, we often need to aggregate data in order to harmonise datasets. In doing so, we often lose a lot of information about the spatial structure and environmental heterogeneity of data measured at finer resolution. The issues around scale disconnects are both conceptual and practical: Conceptual issues Technical issues The scale we measure this stuff at varies too Ecological response ... Read More

Feed: R-bloggers. Author: Keith Goldfeld. In the last two posts, I introduced the notion of time-varying intra-cluster correlations in the context of stepped-wedge study designs. (See here and here). Though I generated lots of data for those posts, I didn’t fit any models to see if I could recover the estimates and any underlying assumptions. That’s what I am doing now. My focus here is on the simplest case, where the ICC’s are constant over time and between time. Typically, I would just use a mixed-effects model to estimate the treatment effect and account for variability across clusters, which is ... Read More

Feed: R-bloggers. Author: hrbrmstr. Despite being a full-on denizen of all things digital I receive a fair number of dead-tree print magazines as there’s nothing quite like seeing an amazing, large, full-color print data-driven visualization up close and personal. I also like supporting data journalism through the subscriptions since without cash we will only have insane, extreme left/right-wing perspectives out there. One of these publications is The Economist (I’d subscribe to the Financial Times as well for the non-liberal perspective but I don’t need another mortgage payment right now). The graphics folks at The Economist are Top Notch and a ... Read More

Maintaining stable finances is a core concern of almost every business, regardless of the size or type, because — unless you happen to be independently wealthy and willing to throw good money after bad — you can’t keep operating once your funds run dry. But it’s often a complicated matter. Payments big and small stack up, economic circumstances shift, and revenue varies. Even if you’re smart and careful, you can still have great difficulty.In recent years, though, the field of big data has moved from an interesting consideration to an influential practical ...
