R boleh jadi merupakan alat analisis data yang paling powerful saat ini. R memiliki fungsi utama mulai dari membaca dan menulis file, memanipulasi dan meringkas data, menjalankan model statistik, hingga membuat grafik-grafik dari data Anda. Fungsi utama ini kemudian dilengkapi oleh fungsi-fungsi yang dimiliki oleh plugin yang dikembangkan oleh komunitas R. Diantara plugin ini, terdapat plugin yang memiliki fungsi sederhana dan plugin yang hanya digunakan pada analisis rumit pada kasus yang sangat spesifik. Dengan fleksibilitas yang dimiliki, R menjadi alat analisis yang sangat populer untuk analis data di bermacam-macam bidang mulai dari pertanian hingga psikologi.
Dalam artikel yang akan kami tulis pada seri R Spatial ini Anda perlu memahami bahwa ketika Anda merasa ragu, coba saja! Tiru contoh yang kami buat, lalu buatlah modifikasi pada perintahnya. Dengan begitu Anda akan mengerti apa yang sebenarnya terjadi. Anda mempelajari sebuah bahasa. Seperti sebuah bahasa nyata, Anda bisa mahir dalam menggunakannya hanya jika Anda sering menggunakannya. Maka Anda harus mengerti bahwa pada awalnya Anda akan kesulitan. Jangan khawatir, kita semua begitu.
Untuk menggunakan R, Anda pasti perlu mengunduh R disini dan menginstalnya. Sebagai tambahan, saya sarankan Anda untuk mengunduh RStudio yang akan membuat pengoperasian R menjadi lebih mudah.
Menginstal R
