ADDING A CHUNK OF RCODE HOW TO

The purpose of this article is to show you how to write the information necessary to a PNG file to give a background color to a PNG file, so that in these situations, the visitor gets something that at least tries to match the site. The good news is that the background color does not have to be cream-cyan, it can be anything you like. There will be situations when you just can't have alpha-transparent PNGs (like in high-security mode), and your images are drawn with the cream-cyan background color. The problem is that they all 'sort of' work.

Together with Command+A (select all) it is a very powerful tool, which saves time.There are lots of articles around the Internet that show you how to get alpha-transparency to work in Internet Explorer 6 and lower.

Magic shortcut: Command+I ( Ctrl+I for Windows/Linux) will indent a selected chunk of code.

Check the following boxes: “Insert spaces for tab” (with “Tab width” equal to chosen number), “Auto-indent code after paste”, and “Vertically align arguments in auto-indent”. Put spaces around all infix binary operators ( =, +, *, =, &, Global options… -> Code -> Editing. # GoodĭO NOT use names of existing function and variables (especially, built-in ones). (reserved for an S3 dispatch) or use CamelCase (reserved for S4 classes definitions). Variable names should be typically lowercase. Generally, names should be as short as possible, still meaningful nouns. Use methods- prefix for S4 class methods. If the file contains only one function, name it by the function name. AllGenerics.R (or AllGeneric.R), a file that stores all S4 generic functions.AllClasses.R (or AllClass.R), a file that stores all S4 classes definitions.If the file is used in a package, then slightly different rules should be folowed: If files should be run in a particular order, then use ascending names. There is nothing bad in having capital case names, just bear in mind UNIX systems are case insensitive, meaning that test.R and Test.R do not differ. If the file is a part of data analysis, then it makes sense to follow the following recommendations:įile names should be lowercase. Instead, a dash ( -) or underscore ( _) should be used. # Goodįile names should not contain / and spaces. There are, however, common rules:įile names should use. The convention actually depends on whether you develop a file for a package, or as a part of data analysis process. In this post, you will learn these “unofficial” rules, their deviations, and most common styles. The story is a bit different if you are working in a team: it is crucial to agree on a convention beforehand and make sure that everyone follows it.Įven though there is no official style guide, R is mature and steady enough to have an “unofficial” convention. If you are coding alone, sticking to your coding style and being consistent is more than enough. At the end of the day, coding style is a set of developers’ preferences. There is no such thing as a “correct” coding style, as there is no such thing as the best color. It, but it sure makes things easier to read. Good coding style is like using correct punctuation. In this context, taking care of your audience means to make your code as readable as possible. And if you did not follow consistently your coding style, reviewing your code can take much longer, than expected. However, even if you don’t, keep in mind that at some point in time, you might come back to your code, for example, to fix an error. It is especially important, if you have collaborators, which depend on your code. The same applies to programming languages: concise, clear and consistent codes are easier to read and edit. The clearer we express ourselves, the better the idea is transferred from our mind to the other. Language is a tool that allows human beings to interact and communicate with each other.
