R language

Course Overview

R is an open source programming language and software environment for statistical computing and graphics. The R language is widely used among statisticians and data miners for developing statistical software and data analysis. Polls, surveys of data miners, and studies of scholarly literature databases show that R’s popularity has increased substantially in recent years.

Section 1: Introduction to Handstands
Welcome to your firs’t video tutorial. This video will start with a simple introduction. Then, You will open up google cause I’ll show you where you can download the blender software and which version of it will we be using in the entire course period
Note: The download link is available with the lecture, plus the .pdf file is also included for you to download if you still need help downloading the software.
An InDesign template is a beautiful thing. If you find yourself creating the same kind of document over and over again, a template can save you a tremendous amount of time. Working with other designers? A template can help make sure you’re all on the same page. And if you need to get clients up and running on their own, a template can provide the guidance they need to execute a design successfully.

Saving time with a great template provides you with in-depth training on Design. Taught by Anne-Marie Concepción as part of the Designing Templates with InDesign
By building in the power tools you need for production—flexible master pages, logical layers, object styles, libraries and snippets, and styles—you’ll have a template that prepares you for success
Templates are a way your small business can save time. When you have documents that you use frequently, such as presentations, minutes, forms and expense reports, you can create them with a template that is already pre-formatted to your specifications. A template also gives your documents a uniform look that can be modified to accommodate your specific needs. Sometimes you may have a PDF document that features a format you wish to use more than once. You can convert it to a Word template so you can use this design as often as necessary.
Setting up layers to streamline production provides you with in-depth training on Design. Photoshop CC now includes Generator, a feature that could mean “no more slices”. Ever. Generator scans your layer names looking for file extensions. Once it finds one it understands, it takes all the pixels it can find on that layer (or, as you will see later, layer group) and saves them to a file of the specified kind
Section 2: Creating a simple master page strategy

While your wrists will certain get stronger from practice and grow accustomed to the stress of the skill, a basic amount of wrist strengthening exercises for several weeks can only help things. I’d recommend working wrist curls and reverse wrist curls for around 6-10 reps for 3 sets. I also strongly recommend trying some sledgehammer levering. Work in 2-3 sets of 3-5 reps. In particular, exercises 1 and 3 are fantastic for building wrist strength and they are much harder than they look! Start with them to get the hang of sledgehammer work before you progress to the other two exercises. I don’t want somebody putting a hole through their floor or their face because they rushed things!
