Since state is a reserved keyword in Truffle's guard mechanism, it should not be possible to use it in a guard definition as this can cause serious problems. The annotation processor should either reject the state keyword in guard definitions or the state temporary variable produced by the processor should be renamed to avoid this conflict.

Here's an example:

Summary

In R, the return statement is not strictly required in functions.

# this returns NULL
gives_nothing <- function(x, y){
    print(x)
    print(y)
}

# this returns the value of n
gives_sum <- function(x, y){
    n <- x + y
    n
}

This means that it can sometimes be difficult to understand, from looking at the code, what a function will return.

How

I have been recreating the plot_component daily and weekly graphs using the forecast dataframe.

forecast = m.predict(future)
fig = m.plot_components(forecast)

Recreating the daily component is straight forward, as it is repeated for every day in the dataset. So can be plotted as:

forecast['daily][:n].plot() 
# Where n = number of readings in 24hr period

However, t

Problem:
catboost version: 0.23.2

Impossible to use custom metric (С++).

I'm happy to announce that I'll be writing the second edition of Data Science at the Command Line (O'Reilly, 2014). This issue explains why I think a second edition is needed, lists what changes I plan to make, and presents a tentative outline. Finally, I have a few words about the process and giving feedback.

Why a second edition?

While the command line as a technology and as a way of w

I'm sorry if I missed this functionality, but CLI version hasn't it for sure (I saw the related code only in generate_code_examples.py). I guess it will be very useful to eliminate copy-paste phase, especially for large models.

Of course, piping is a solution, but not for development in Jupyter Notebook, for example.
