How can I plot with 2 different y-axes?
...orm(10)
## second data set on a very different scale
z <- runif(10, min=1000, max=10000)
par(mar = c(5, 4, 4, 4) + 0.3) # Leave space for z axis
plot(x, y) # first plot
par(new = TRUE)
plot(x, z, type = "l", axes = FALSE, bty = "n", xlab = "", ylab = "")
axis(side=4, at = pretty(range(z)))

In JavaScript, is returning out of a switch statement considered a better practice than using break?
...g:
var foo = "bar";
if(foo == "bar") {
return 0;
}
else {
return 100;
}
Based on this, the argument could be made that option one is better practice.
In short, there's no clear answer, so as long as your code adheres to a consistent, readable, maintainable standard - that is to say don'...
How do you get the magnitude of a vector in Numpy?
...imeit.timeit('np.linalg.norm(x)', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0450878
>>> timeit.timeit('np.sqrt(x.dot(x))', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0181372
EDIT: The real speed improvement comes when you have to take the norm of m...
Why not infer template parameter from constructor?
...t the compiler supports what you asked. Then this code is valid:
Variable v1( 10); // Variable<int>
// Some code here
Variable v2( 20.4); // Variable<double>
Now, I have the same type name (Variable) in the code for two different types (Variable and Variable). From my subjective poi...
How to force R to use a specified factor level as reference in a regression?
...e the relevel() function. Here is an example:
set.seed(123)
x <- rnorm(100)
DF <- data.frame(x = x,
y = 4 + (1.5*x) + rnorm(100, sd = 2),
b = gl(5, 20))

Now alter the factor b in DF by use of t...
What does “1 line adds whitespace errors” mean when applying a patch?

So we can just move it to the "basic" config, which fixes add--interactive, along with any other script in the same boat, with a very low risk of hurting any plumbing users.
