It’s a sequence of characters, which can be letters, numbers, symbols, and other types of characters. ![]() Understanding Reactive Programming in Shiny R FrameworkĪ string is a data type in R, similar to a text document or a word processor document.Tips and Tricks for Optimizing Shiny R Applications.Shiny R Framework for Teaching and Learning Data Science.Shiny R Framework for Machine Learning and Predictive Analytics.Shiny R Framework for Data Science and Statistical Analysis.Real-time Data Visualization with Shiny R Framework.Performance Tuning and Scaling of Shiny R Applications.Integrating Shiny R with Other Technologies and Tools.How to Install and Set Up Shiny R Framework.Handling Large Datasets in Shiny R Applications.Enhancing Shiny R Applications with Advanced Features.Deploying Shiny R Applications to the Cloud.Debugging and Troubleshooting Shiny R Applications.Customizing the Look and Feel of Shiny R Applications.Creating User-friendly Dashboards with Shiny R Framework.Building Interactive Web Applications with Shiny R Framework.Building Collaborative Applications with Shiny R Framework.Best Practices for Developing Robust Shiny R Applications.Authentication and Authorization in Shiny R Framework.How do I match zero or more occurrences of a pattern using regular expressions.How do I match the beginning or end of a line using regular expressions.How do I match any character using regular expressions.How do I match a word boundary using regular expressions.How do I match a specific text pattern using regular expressions.How do I match a specific number of occurrences of a pattern using regular expressions.How do I match a specific character using regular expressions.How do I match a range of characters using regular expressions.Using magrittr in data manipulation workflows.How to use the %>% operator in magrittr.Comparing magrittr to other R frameworks.Common mistakes and pitfalls to avoid with magrittr.Combining magrittr with other R packages.Working with time periods and durations in lubridate.Visualizing date and time data with ggplot2 and lubridate.Using lubridate with tidyverse packages.Using lubridate with data from different time zones.Tips and tricks for efficient date and time manipulation with lubridate.Parsing and formatting dates and times in lubridate.Handling leap years and other calendar quirks with lubridate.Handling daylight saving time transitions in lubridate.Extracting specific elements from date and time objects in lubridate.Dealing with missing or incomplete date and time data in lubridate.Date and time manipulation using lubridate. ![]() Customizing date and time formats in lubridate.Creating new date and time objects with lubridate.Converting date and time formats using lubridate.Common mistakes and pitfalls to avoid with lubridate.Calculating time differences and intervals with lubridate.Advanced date and time manipulation techniques with lubridate.How to insert an item in an array at a specific index.How to format numbers as currency strings.How to find the intersection or difference of two arrays.How to find the absolute value of a number.How to find all unique items in an Array.How to convert a byte array to a hexadecimal string.How to check if a String is a Palindrome.How to Find the Last Occurrence of a Substring in a String.How to Find the First Occurrence of a Substring in a String.How to Find Index of a Character in a String.How to Convert Binary Tree to Doubly Linked Lists.Integer() will raise an ArgumentError, so specify that. A bare rescue (such as "rescue nil") will rescue from any error which inherits from StandardError and may interfere with the execution of your program in ways you don't expect. You should be careful to rescue from a particular exception. You'd still need your number_or_nil method if you want the behavior to be that nil is returned when a string cannot be converted. Integer('5abc') #=> ArgumentError: invalid value for Integer(): "5abc" It will raise an ArgumentError error if the string cannot convert to an integer. ![]()
