Understanding the plot() Error: seq.int(0, to0 - from, by) : ’to’ must be a finite number The error message “seq.int(0, to0 - from, by) : ’to’ must be a finite number” is a common issue encountered when using the base R plot() function. In this article, we will delve into the details of this error and explore possible solutions. What does seq.int() do? The seq.int() function generates an integer sequence over a specified range.

Here is the code to solve the problem: import pandas as pd import numpy as np def f(df, b): d = df.set_axis(df.columns.str.split('_', expand=True), axis=1, inplace=False) parts = np.exp(d.stack().mul(b).sum(1).unstack()) preds = pd.concat({'P': parts.div(parts.sum(1), axis=0)}, axis=1).round(3) d = d.join(preds) d.columns = list(map('_'.join, d.columns)) return d df = pd.DataFrame({ 'X1_123': [6.75, 7.46, 2.05], 'X1_456': [4.69, 4.94, 7.30], 'X1_789': [9.59, 3.01, 4.08], 'X2_123': [5.52, 1.78, 7.02], 'X2_456': [9.69, 1.38, 8.24], 'X2_789': [7.40, 4.68, 8.49], }) b = pd.
