Arithmetic Operators

Following table shows the arithmetic operators supported by R language. The operators act on each element of the vector.

Relational Operators

Following table shows the relational operators supported by R language. Each element of the first vector is compared with the corresponding element of the second vector. The result of comparison is a Boolean value.

Logical Operators

Following table shows the logical operators supported by R language. It is applicable only to vectors of type logical, numeric or complex. All numbers greater than 1 are considered as logical value TRUE.

Miscellaneous Operators

These operators are used to for specific purpose and not general mathematical or logical computation.

What is a demos package?

Packages may also include extended code demonstrations (“demos”). The command demo () lists all demos for all packages in your library, while demo (package="package-name") (e.g., demo (package="stats")) lists demos in a particular package.

How to run a demo in Java?

To run a demo, call the demo () function with the quoted name of the demo (e.g., demo ("nlm") ), specifying the name of the package if the name of the demo isn’t unique (e.g., demo ("nlm", package="stats"), where , in this case, the package name need not be given explicitly).

Is it good to ask for help in R?

Before asking others for help, it’s generally a good idea for you to try to help yourself. R includes extensive facilities for accessing documentation and searching for help . There are also specialized search engines for accessing information about R on the internet, and general internet search engines can also prove useful ( see below ).

What is apropos in R?

The apropos () function searches for objects, including functions, directly accessible in the current R session that have names that include a specified character string. This may be a literal string or a regular expression to be used for pattern-matching (see ?"regular expression" ). By default, string matching by apropos () is case-insensitive. For example, apropos ("^glm") returns the names of all accessible objects that start with the (case-insensitive) characters "glm".

What is rsitesearch?

RSiteSearch () uses an internet search engine (also see below) to search for information in function help pages and vignettes for all CRAN packages, and in CRAN task views (described below ). Unlike the apropos () and help.search () functions, RSiteSearch () requires an active internet connection and doesn’t employ regular expressions. Braces may be used to specify multi-word terms; otherwise matches for individual words are included. For example, RSiteSearch (" {generalized linear model}") returns information about R functions, vignettes, and CRAN task views related to the term "generalized linear model" without matching the individual words "generalized", "linear", or "model".

What is help.start in R?

help.start () starts and displays a hypertext based version of R’s online documentation in your default browser that provides links to locally installed versions of the R manuals, a listing of your currently installed packages and other documentation resources.

Why use pipes in R?

In short, here are four reasons why you should be using pipes in R: 1 You'll structure the sequence of your data operations from left to right, as apposed to from inside and out; 2 You'll avoid nested function calls; 3 You'll minimize the need for local variables and function definitions; And 4 You'll make it easy to add steps anywhere in the sequence of operations.

What does R mean in programming?

R is a functional language, which means that your code often contains a lot of parenthesis, ( and ). When you have complex code, this often will mean that you will have to nest those parentheses together. This makes your R code hard to read and understand. Here's where %>% comes in to the rescue!

When are arguments computed in R?

Arguments within functions are only computed when the function uses them in R. This means that no arguments are computed before you call your function! That means also that the pipe computes each element of the function in turn.

Can you use placeholders in a right hand expression?

It is straight-forward to use the placeholder several times in a right-hand side expression. However, when the placeholder only appears in a nested expressions magrittr will still apply the first-argument rule. The reason is that in most cases this results more clean code.

What is unary function?

Unary functions are functions that take one argument. Any pipeline that you might make that consists of a dot ., followed by functions and that is chained together with %>% can be used later if you want to apply it to values. Take a look at the following example of such a pipeline:
