This is my test run using GoogleVis, a R! package

My test-run using GoogleVis, a R! package

This week, I attended a R! training class instructed by Dr. Aedin Culhane, a wonderful teacher. I was taught that I can use the GoogleVis, a R! package, to draw a moving bubble plot. It's amazing. Here is the output we used in the class.
    R! Codes: library(googleVis)
             M <- gvisMotionChart(Fruits, "Fruit", "Year")
             plot(M)
             cat(M$html$chart, file="tmp.html")
Here is the more information about: Using the Google Visualisation API with R

FW: A Firm Diagnosis of Frailty - NYTimes.com

A Firm Diagnosis of Frailty
Source: NYTimes.com


... After years of observing and working with older patients, Dr. Fried recognized objective hallmarks of frailty, and in the 1990s developed a definition of frailty in people 65 and older that called for the diagnosis when three or more of the following five criteria were present: unintentional weight loss of 10 pounds or more in the past year, self-reported exhaustion, weakness as measured by grip strength, slow walking speed and low physical activity. The presence of one or two of those criteria would identify a person as "pre-frail."

Update on the alternative to HOMA-IR and HOMA-b


Update on the HOMA-IR and HOMA-b
Source:  iHOMA2
iHOMA2 is an interactive, 24-variable, HOmeostatic Model of Assessment with the baseline default characteristics of the HOMA2 computer model of fasting insulin:glucose interaction. iHOMA2 enables the mathematical functions describing the organs and tissues involved in the glucose and hormonal compartments to be modified using simple visual analogue controls. The model can be used to evaluate therapeutic agents and predict effects on fasting glucose and insulin and on beta cell function and insulin sensitivity.
Here is the main URL for the iHOMA2 website.

I am not a fan of iHOMA2; I post it here as a future reference.
