How to permanently set R working directory

Image
       Using R Studio If you are using RStudio for R Programming just go to Tools -> Global Options... -> General one can set the default working directory. Also under Session one can Set Working Directory To Source File Location and To Files Pane Location with single click and with a graphical tool to any directory. Setting a convenient default is of course useful, but at least I have at most one project (in general meaning of the word and not just in R meaning of the word) in one folder so I have to switch the working directory anyway between projects.

Babies using mobile media, new study reveals Tech babies A new study has revealed the extent to which babies are using digital devices. Source: News Limited A new study has revealed the extent to which babies are using digital devices.

And by their first birthday, one in seven infants is using devices for at least an hour a day. The results of the First Exposure and Use of Mobile Media in Young Children survey was presented to the Pediatric Academic Societies annual meeting in San Diego on the weekend.

Earthquake kills 3,218 people in Nepal, over 60 dead in India If earthquake predictions, meaning alerts days or weeks ahead, are still a distant goal, progress has been made on early warnings of earthquakes, giving precious seconds that can save lives, according to Reuters . Earthquake early-warning systems have been deployed in only a handful of the world's seismic hot zones. They can warn of quakes as much as a few minutes before they strike. Countries with such systems include Mexico, Japan, and the United States, where the most advanced system is California's state-run ShakeAlert. "If Nepal had a seismic network that operated as the seismic stations in Northern California did in the Napa quake, people in Kathmandu would probably have had 15 to 20 seconds warning," said seismologist Peggy Hellweg. That could have been enough to take cover under tables or even escape some collapsing buildings. Yesterday in meeting with PM,we took lot of decisio
