Global Warming in My Lifetime – July’s Story

NASA GISS has a great web application that let’s users generate  maps of global monthly temperature anomalies in 2 degree grids.  I’ve made a 27 second video of 7 decade maps for July to see how global temperature anomalies have progressed through my life so far.

Here’s the link to NASA GISS’s map application page. It’s very easy to use.

My video shows 7 maps, each showing the July average for each of the 16,200 grid cells (2×2 lat/lon).

rpanel Package – Adds Interactive Capabilites to R

This post presents a short video that shows an interactive regression application using the rpanel package.

rpanel

Hadley Wickham’s Crantastic site currently lists 1,531 R packages.  This post shows how I have used one of these  packages, rpanel, to build an interactive regression tool,  similar to the interactive regression tool I built in Excel.

Excel users often add check boxes, sliders, drop down lists to add some interactive capabilities to worksheets. rpanel provides the same type of capability in the R environment. Since a video is worth a lot of text, here’s a short video that shows my interactive R regression application:

rpanel has been developed by Adrian Bowman, et al at the University of Glasgow, Department of Statistics. They have several excellent support documents and scripts at this link.

The script and source data file are available at this link.

Only 1,530 R packages to go!

Interesting Data Tools: Tinkerplots

There are many data analysis and charting tools that Excel users should check out to see what is available in the world outside Excel. I’ll be posting about interesting tools that I find and/or readers tell me about.  Here’s my first – Tinkerplots Continue reading

SAS – JMP 8’s Interactive Panel Chart Video

One of my ProcessTrends.Com readers, Andrew, sent me a link to a SAS – JMP 8 video on panel charts. I checked it out and was impressed.

Here’s the link.  The 1 min 41 sec  video gives you a good idea of what JMP can do to interactively make panel charts.  If you are an Excel user, be sure to check it out to see what capabilities you are missing.

What do you think?  Any chance that Microsoft will see the light and make Excel a real analysis tool?
