Read an Excel file directly from a R script
...ng XLConnect are, in my opinion:
Cross platform. XLConnect is written in Java and, thus, will run on Win, Linux, Mac with no change of your R code (except possibly path strings)
Nothing else to load. Just install XLConnect and get on with life.
You only mentioned reading Excel files, but XLConnec...

...cies).
Once you learn to read smali, it is almost as reading the original java code (but with way more LOCs). So, any code you add to check for keys can be found and deleted or replaced. You don't even need to recompile each time to eliminate more than one (some searches do miracles to find similar...

What is an “unwrapped value” in Swift?
...you write much safer code. E.g. imagine all the null pointer exceptions in Java crashing a program because somebody forgot to check for null. Or weird behaviour on Objective-C because you forgot to check for nil. With Optional type you can't forget to deal with nil. The compiler forces you to deal w...
What is the Scala identifier “implicitly”?
...1) //
res23: AnyRef{def min(i: Int): Int} = 1
scala> .getClass
res24: java.lang.Class[_] = class scala.runtime.RichInt
Implicit Views can also be triggered when an expression does not conform to the Expected Type, as below:
scala> 1: scala.runtime.RichInt
res25: scala.runtime.RichInt = 1

How does C compute sin() and other math functions?
...will generate code that calls these assembly instructions. (By contrast, a Java compiler will not. Java evaluates trig functions in software rather than hardware, and so it runs much slower.)
Chips do not use Taylor series to compute trig functions, at least not entirely. First of all they use CO...
Performance difference for control structures 'for' and 'foreach' in C#
...
Note: this answer applies more to Java than it does to C#, since C# doesn't have an indexer on LinkedLists, but I think the general point still holds.
If the list you're working with happens to be a LinkedList, the performance of the indexer-code (array-styl...
