Consider refactoring with ifelse logic and filtered vectors using a user defined method since logic is very similar but across different columns:

You can replace your 0 values with NAs, for example with, dplyr::na_if(0) on your dataframe:

The poster wants two things

1. lines with colors depending on z-values
2. animation of the lines over time

In order to achieve(1) one needs to cut up each line in separate segments and assign a color to each segment; in order to obtain a colorbar, we need to create a scalarmappable object that knows about the outer limits of the colors.

For achieving 2, one needs to either (a) save each frame of the animation and combine it after storing all the frames, or (b) leverage the animation module in matplotlib. I have used the latter in the example below and achieved the following:

The problem you have in your code is with the empty strings in your items.txt file. When there's an empty string, fire would resolve to [''], which is a list of only 1 item, so you get an error when the code tries to run c = fire[1]. You can add a check to see if it's an empty line or not:

The trick is to pick one of the arrays and loop through that with a for loop so you get a counter. You can then pick the item from each of the arrays matching the current counter and display it - this gets you the results which belong together.

(For it to work, all the arrays must have the same number of items in them, but from what you've shown that shouldn't be a problem.

Try something like this:

An array is a list of data, it has no built-in visual representation (largely because it has no guaranteed structure within it). You need to decide how you want to display that data and write some code to loop through the array and output the data in the format you want.

At the absolute simplest you can just output each item on a separate line, or separated by commas. For that you need to build up the mail body string gradually so you can concatenate the values together. To make for less repetition, a function would be useful here, so you can use it to display the contents of all the arrays in a consistent way.

Something like this should work:

Starting simply with NLP makes it easier to understand and also to appreciate the more advanced systems.

This gives what you're looking for:

The function getSug gets called on the 3rd line.

Instead of onclick function you just invoke it at the definition line.

I have the impression you need to sort out your problem - there is too many things envolved and they do not fit to the error message.
Did you really post the actual versions of your files (urls.y ...)?
