As companies’ global partner ecosystems expand, remote suppliers, contractors and other external parties are just as likely to require access to some key enterprise applications as are full-time staffers working from branch locations, home offices or the field.

I mentioned at the outset that R syntax is a bit quirky, especially if your frame of reference is, well, pretty much any other programming language. Here are some unusual traits of the language you may find useful to understand as you embark on your journey to learn R.

One of the most appealing things about R is its ability to create data visualizations with just a couple of lines of code.

I’ve put together a few collections of tips to help readers get more from their Apple Watch. This short collection should help any busy enterprise professional get more done, faster.

So you've read your data into an R object. Now what?

Examine your data object

Before you start analyzing, you might want to take a look at your data object's structure and a few row entries. If it's a 2-dimensional table of data stored in an R data frame object with rows and columns -- one of the more common structures you're likely to encounter -- here are some ideas. Many of these also work on 1-dimensional vectors as well.

Many of the commands below assume that your data... Читать дальше...

R is hot. Whether measured by more than 10,000 add-on packages, the 95,000+ members of LinkedIn's R group or the  more than 400 R Meetup groups currently in existence, there can be little doubt that interest in the R statistics language, especially for data analysis, is soaring.

Once you've installed and configured R to your liking, it's time to start using it to work with data. Yes, you can type your data directly into R's interactive console. But for any kind of serious work, you're a lot more likely to already have data in a file somewhere, either locally or on the Web. Here are several ways to get data into R for further work.

If you buy a top-of-the-line, 1TB computer, you might expect to get 1TB of storage. Yes? But if you shell out $2,700 for a 1TB Microsoft Surface Pro 2017 (or a princely $2,960 if you want a keyboard and pen), you actually get two 512GB SSD drives. And therein lies a problem. Two of them, actually.

Given that so many of the details of our digital lives are either with us (on our smartphones) or easily accessible (via the web), you should be doing everything you can to protect that information and data. On iPhones and iPads, data is largely kept in a vault, sealed behind strong encryption and (hopefully) a strong password. Even if the device is lost or stolen, chances are good that encryption will keep data safe. (That vault is secure enough to frustrate even the FBI.)
