Intelligent point label placement in R
...phisticated algorithms that have been presented is to make in-place simple transformations to the dataframe.
I illustrate this with ggplot2 because I'm more familiar with that syntax than base R plots.
df <- data.frame(x = x, y = y, z = ShortSci)
library("ggplot2")
ggplot(data = df, aes(x = x, ...

That's great if you're sick of repeatedly writing code to process the results of $http yourself. To anyone else, $resource adds a cryptic layer of syntax and parameter passing that is con...

...l', 'rb') as fin:
vectorizer, clf = pickle.load(fin)
X_new = vectorizer.transform(new_samples)
X_new_preds = clf.predict(X_new)
Before dumping the vectorizer, one can delete the stop_words_ property of vectorizer by:
vectorizer.stop_words_ = None
to make dumping more efficient.
Also if your ...
