Data visualization is a powerful tool for gaining insights from your data. In R, you have a plethora of libraries and functions at your disposal to create stunning and informative plots. One common task is to plot a subset of your data, which allows you to focus on specific aspects or trends within your dataset. In this blog post, we’ll explore various techniques to plot subsets of data in R, and I’ll explain each step in simple terms. Don’t worry if you’re new to R – by the end of this post, you’ll be equipped to create customized plots with ease!
Before we start, make sure you have R and RStudio installed on your computer. If not, you can download them from R’s official website and RStudio’s website.

If and when you set out to traverse through a Unix directory hierarchy, whether to inventory it or to find something, you have a decision to make. I can put this decision in technical terms, about whether you use stat() or lstat() when identifying subdirectories in your current directory, or put it non-technically, about whether or not you follow symbolic links that happen to point to directories. As you might guess, there are two possible answers here and neither is unambiguously wrong (or right). Which answer programs choose depends on their objectives and their assumptions about their environment.

The Linux Foundation launched the LFCS (Linux Foundation Certified Sysadmin) certification, a shiny chance for system administrators everywhere to demonstrate, through a performance-based exam, that they are capable of performing overall operational support on Linux systems: system support, first-level diagnosing and monitoring, plus issue escalation, when required, to other support teams.
The series will be titled Preparation for the LFCS (Linux Foundation Certified Sysadmin) Parts 1 through 33 and cover the following topics:
