Fixing the Mismatch in Input Sequences for the `adist` Function in R
The bug in the code is due to a mismatch between the lengths of the input sequences and the output sequence. The adist function expects the input sequences to have the same length, but in the given example, the sequences ‘x’, ‘hi’, ‘y’ have different lengths. To fix this bug, we need to ensure that the input sequences have the same length before calling the adist function. Here’s an updated version of the code:

Summarizing Tibbles with Custom Functions: A Comprehensive Approach for Data Analysis
Based on the provided code and data, it appears that you want to create a function ttsummary that takes in a tibble data and a list of functions funcs. The function will apply each function in funcs to every column of data, summarize the results, and return a new tibble with the summarized values. Here’s an updated version of your code with some additional explanations and comments: # Define a function that takes in data and a list of functions ttsummary <- function(data, funcs) { # Create a temporary tibble to store the column names st <- as_tibble(names(data)) # Loop through each function in funcs for (i in 1:length(funcs)) { # Apply the function to every column of data and summarize the results tmp <- t(summarise_all(data, funcs[[i]]))[,1] # Add the summarized values to the temporary tibble st <- add_column(st, tmp, .
