Whether you&#8217;re a budding data scientist, analyst, or researcher, R provides a versatile environment for crunching numbers, creating visualizations, and conducting sophisticated analyses.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><a class=\"maxbutton-1 maxbutton maxbutton-subscribe-to-api external-css btn\" href=\"https:\/\/eodhd.com\/register\"><span class='mb-text'>Register &amp; Get Data<\/span><\/a><\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-setting-up-your-environment\">Setting Up Your Environment<\/h2>\n\n\n\n<p>Before we embark on this R journey, ensure you have R and RStudio installed on your machine. RStudio is an integrated development environment (IDE) that makes working with R more user-friendly. You can download R from <a href=\"https:\/\/cran.r-project.org\/mirrors.html\" target=\"_blank\" rel=\"noreferrer noopener\">CRAN<\/a>&nbsp;and RStudio from <a href=\"https:\/\/www.rstudio.com\/products\/rstudio\/download\/\" target=\"_blank\" rel=\"noreferrer noopener\">RStudio&#8217;s official website<\/a>.<\/p>\n\n\n\n<p>The only one available way to use R is RStudio. So, all next moves will be based on RStudio.<\/p>\n\n\n\n<p>Before we proceed with fetching the data, we need to install the EODHD APIs&nbsp;R&nbsp;Financial Library by running appropriate&nbsp;command in&nbsp;the left bottom&nbsp;command line and run it by pressing Enter.<\/p>\n\n\n\n            <div class=\"code__wrapper\">\n                <div class=\"code__content\">\n                    \n<pre class=\"wp-block-code has-white-color has-black-background-color has-text-color has-background\"><code lang=\"python\" class=\"language-python\">install.packages(\"eodhd\")<\/code><\/pre>\n\n                <\/div>\n                <div class=\"code__btns\">\n                    <button class=\"code__copy\" class=\"copy\" title=\"Copy url\">\n                        <svg class=\"code__copy__icon\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                            <use xlink:href=\"\/img\/icons\/copy.svg#copy\"><\/use>\n                        <\/svg>\n                        <img decoding=\"async\" class=\"code__copy__approve\" alt=\"\" src=\"\/img\/approve_ico.svg\" loading=\"eager\">\n                    <\/button>\n                <\/div>\n            <\/div>\n        \n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1919\" height=\"909\" src=\"https:\/\/eodhd.com\/financial-academy\/wp-content\/uploads\/2023\/12\/Screenshot_1-2.png\" alt=\"\" class=\"wp-image-4146\" style=\"width:836px;height:auto\"\/><\/figure>\n\n\n\n<p>Wait until&nbsp;all packages are be installed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-importing-the-required-library\">Importing the Required Library<\/h2>\n\n\n\n            <div class=\"code__wrapper\">\n                <div class=\"code__content\">\n                    \n<pre class=\"wp-block-code has-white-color has-black-background-color has-text-color has-background\"><code lang=\"python\" class=\"language-python\">library(\"eodhd\")<\/code><\/pre>\n\n                <\/div>\n                <div class=\"code__btns\">\n                    <button class=\"code__copy\" class=\"copy\" title=\"Copy url\">\n                        <svg class=\"code__copy__icon\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                            <use xlink:href=\"\/img\/icons\/copy.svg#copy\"><\/use>\n                        <\/svg>\n                        <img decoding=\"async\" class=\"code__copy__approve\" alt=\"\" src=\"\/img\/approve_ico.svg\" loading=\"eager\">\n                    <\/button>\n                <\/div>\n            <\/div>\n        \n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1042\" height=\"402\" src=\"https:\/\/eodhd.com\/financial-academy\/wp-content\/uploads\/2023\/12\/Screenshot_3.png\" alt=\"\" class=\"wp-image-4149\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-accessing-the-eodhd-api\">Accessing the EODHD API<\/h2>\n\n\n\n<p>First, we need to check all available functions. Let&#8217;s move to <a href=\"https:\/\/github.com\/EodHistoricalData\/EODHD-APIs-R-Financial-Library\"><u>GitHub EODHD APIs R Financial Library<\/u><\/a> where we need to click the <a href=\"https:\/\/github.com\/EodHistoricalData\/EODHD-APIs-R-Financial-Library\/blob\/main\/README.md\"><u>README<\/u><\/a>&nbsp;file and check all available functions.<\/p>\n\n\n\n<p>Finally, after we choose the preferred&nbsp;function, we can try to retrieve&nbsp;the data. As an example let&#8217;s take \u201cEnd of day historical stock market data\u201d, the \u201capi_token\u201d and \u201csymbol\u201d parameters will be required. In this example, we will use the demo API key provided by EODHD, but in your real application, you should use your registered API key.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1895\" height=\"909\" src=\"https:\/\/eodhd.com\/financial-academy\/wp-content\/uploads\/2023\/12\/Screenshot_2.png\" alt=\"\" class=\"wp-image-4150\"\/><\/figure>\n\n\n\n<p class=\"bordered_paragraph\">1.
