First of all, we will learn about R list, then we will discuss how to create, access and modify lists in R with the help of examples.<\/p>\n<h2>What is R List?<\/h2>\n<p>R list is the object which contains elements of different types \u2013 like <em>strings, numbers, vectors and another list<\/em> inside it. R list can also contain a matrix or a function as its elements. The list is created using the\u00a0<em>list() <\/em>function in R. In other words, a list is a generic vector containing other objects.<\/p>\n<p><strong>For example<\/strong>:<\/p>\n<p>The variable x is containing copies of three vectors n, s, b and a numeric value 3.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">#Author DataFlair\r\nvec &lt;- c(1,2,3)\r\nchar_vec &lt;- c(\"Hadoop\", \"Spark\", \"Flink\", \"Mahout\")\r\nlogic_vec &lt;- c(TRUE, FALSE, TRUE, FALSE)\r\nout_list &lt;- list(vec, char_vec, logic_vec)\r\nout_list<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<h2><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-66729 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123.jpg\" alt=\"vec c 123 - R List\" width=\"1299\" height=\"741\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123.jpg 1299w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123-150x86.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123-300x171.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123-768x438.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123-1024x584.jpg 1024w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/vec-c-123-520x297.jpg 520w\" sizes=\"auto, (max-width: 1299px) 100vw, 1299px\" \/><\/a><\/h2>\n<p><em><strong>Wait!

With R lists, programmers can effortlessly organize and manipulate data, whether it comprises vectors, matrices, or even other lists. This flexibility extends to encapsulating complex data structures, making lists invaluable for representing hierarchical relationships and composite objects.<\/p>\n<p>Furthermore, the ability to access, modify, and iterate through list elements facilitates seamless data processing and analysis workflows. Whether employed for data manipulation, statistical modeling, or algorithm development, R lists empower programmers with a powerful tool for managing diverse data sets and facilitating efficient data-driven decision-making processes.<\/p>\n<h3>How to Create Lists in R Programming<\/h3>\n<p>In this section of the R list tutorial, we will create R list with the help of an example.<\/p>\n<p>Let&#8217;s create a list containing <em>string, numbers, vectors and logical values.<\/em><\/p>\n<p><strong>For example<\/strong>:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">#Author DataFlair\r\nlist_data &lt;- list(\"Red\", \"White\", c(1,2,3), TRUE, 22.4)\r\nprint(list_data)<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<h2><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-66730 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data.jpg\" alt=\"list-data\" width=\"1299\" height=\"741\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data.jpg 1299w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data-150x86.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data-300x171.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data-768x438.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data-1024x584.jpg 1024w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/list-data-520x297.jpg 520w\" sizes=\"auto, (max-width: 1299px) 100vw, 1299px\" \/><\/a><\/h2>\n<h3>How to Name List Elements in R Language<\/h3>\n<p>In this section, we will learn to name the R list elements with the help of an example.<\/p>\n<p>Let&#8217;s create a list containing <em>a vector, matrix, and list.<\/em><\/p>\n<p><strong>For example<\/strong>:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">#Author DataFlair\r\ndata_list &lt;- list(c(\"Jan\",\"Feb\",\"Mar\"), matrix(c(1,2,3,4,-1,9), nrow = 2),list(\"Red\",12.3))\r\nnames(data_list) &lt;- c(\"Monat\", \"Matrix\", \"Misc\")\r\nprint(data_list)<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-66731 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list.jpg\" alt=\"data-list\" width=\"1299\" height=\"741\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list.jpg 1299w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list-150x86.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list-300x171.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list-768x438.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list-1024x584.jpg 1024w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/data-list-520x297.jpg 520w\" sizes=\"auto, (max-width: 1299px) 100vw, 1299px\" \/><\/a><\/p>\n<p><em><strong>You must definitely learn to <a href=\"https:\/\/data-flair.training\/blogs\/r-matrix-operations-applications\/\">Create and Access R Matrix<\/a><\/strong><\/em><\/p>\n<h3>How to Access R List Elements<\/h3>\n<p>Let&#8217;s now understand how to access lists elements in R programming.<\/p>\n<p>Create an R list containing a vector, list and matrix.

to Vector<\/h3>\n<p>A list can be converted to a vector so that the elements of the vector can be used for further manipulation. All the arithmetic operations on vectors can be applied after the list\u00a0is converted\u00a0into\u00a0vector. To do this conversion, we can use the\u00a0<em>unlist()<\/em>\u00a0function. It takes the list as input and produces a vector.<\/p>\n<p><strong>For example:<\/strong><\/p>\n<p><strong>Create lists.<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">int_list &lt;- list(1:5)     #Author DataFlair\r\nprint(int_list)\r\nint_list2 &lt;- list(10:14)\r\nprint(int_list2)<\/pre>\n<p><strong>Convert the lists to vectors.<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">vec1 &lt;- unlist(int_list)\r\nvec2 &lt;- unlist(int_list2)\r\nprint(vec1)\r\nprint(vec2)<\/pre>\n<p><strong>Now add the vectors.<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">sum &lt;- vec1 + vec2 \r\nprint(sum)<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-66737 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list.jpg\" alt=\"int_list\" width=\"1299\" height=\"741\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list.jpg 1299w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list-150x86.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list-300x171.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list-768x438.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list-1024x584.jpg 1024w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2017\/09\/int_list-520x297.jpg 520w\" sizes=\"auto, (max-width: 1299px) 100vw, 1299px\" \/><\/a><\/p>\n<p><em><strong>Must Learn &#8211;
