Step 7: Install and load dplyr to manipulate datasets in R > install.packages("dplyr") > library(dplyr) Attaching package: ‘dplyr’ The following objects are masked from ‘package:stats’: filter, lag The following objects are masked from ‘package:base’: intersect, setdiff, setequal, union...
When you test an algorithm for data processing or machine learning, you often don’t need the entire dataset. It’s convenient to load only a subset of the data to speed up the process. The pandas read_csv() and read_excel() functions have some optional parameters that allow you to sel...
If you've worked with Excel before, you know that you can highlight important values with different colors, font styles, etc. The idea of using these styles and colors is to communicate the information in an effective way. You can do similar work with pandas dataframes too, using conditiona...
A DataFrame is a structure that we use to store data. DataFrames have a row-and-column structure, like this: If you’ve worked with Microsoft Excel, you should be familiar with this structure. A Pandas DataFrame is very similar to an Excel spreadsheet, in that a DataFrame has rows, colu...
