Formatting POSIXct: Removing Seconds from Timestamps ================================================================= In this article, we will delve into the world of time formats and explore how to remove seconds from POSIXct timestamps using R’s formatting capabilities. Understanding POSIXct Timestamps POSIXct (Portable Operating System Interface for Unix) is a type of date-time object that allows us to store dates and times in a standardized way. This format is commonly used in R programming, particularly with the POSIXct class in the base R package.

Based on the provided code and explanation, it appears that the task is to read an Excel file (.xls) and convert its contents into a list of lists in R. The code uses the tibble package for data manipulation and the readxl package for reading the Excel file. Here’s a summary of the steps: Read the Excel file using readxl. Create a new tibble with column names “file” and “date_admin”. Use map() to create a list of lists, where each inner list corresponds to the contents of the Excel file.

Understanding Python Pandas Method Chaining with Assign and Strsplit Python pandas is a powerful library used for data manipulation and analysis. One of its most useful features is method chaining, which allows you to perform multiple operations on a DataFrame in a single line of code. In this article, we will explore how to use the assign function along with strsplit to create a new column from a split of another column.
