In this example we will ask the bitcoin network for the merkle block number 442603. In order to do this we need to send a filterload message and then we have to send a getdata message using the inventory type MSG_MERKLEBLOCK.

Passing in an as= attribute to template will allow you to switch out the default {{item}} syntax for something that is more customized to the module you are working with. In this case, we want to grab the ...

Consider a basic class containing an object with getters and setters in Java: public class CountHolder { private int count = 0; public int getCount() { return count; } public void setCount(int c) { count = c; } } We can't access the count variable because it's private. But we can ac...

One needs the predicted probabilities in order to calculate the ROC-AUC (area under the curve) score. The cross_val_predict uses the predict methods of classifiers. In order to be able to get the ROC-AUC score, one can simply subclass the classifier, overriding the predict method, so that it would a...

First lets create a vector called Vector1: set.seed(123) Vector1 <- rnorm(20) And add missing data to it: set.seed(123) Vector1[sample(1:length(Vector1), 5)] <- NA Now we can use the is.na function to subset the Vector Vector1 <- Vector1[!is.na(Vector1)] Now the resulting vect...
