Tanya 82 : R-CRAN, alternatif pengolah statistik pengganti SPSS

Tanya
Assalamu alaikum Pak, saya mahasiswi semester akhir, sedang butuh perangkat lunak pengolah statistik yang non bajakan. SPSS asli mahal sekali ternyata. Ada solusi Open Source-nya tidak ?
Terima kasih Pak, say a doakan blognya tetap ramai 😀
Wassalam,
Jawab :
Anda bisa gunakan R-Project.
Ada Tampilan GUI-nya yakni RKward, tampak seperti screenshot dibawah ini : (Klik Gambar untuk melihat dalam kualitas yang lebih baik)

Di Ubuntu bisa diinstall dari Ubuntu Software Centre atau via terminal dengan perintah :

sudo apt-get install rkward

Setelah itu bisa anda akses lewat menu Application –> Science –> RKward

Atau jika anda ingin menggunakan versi console-nya cukup install dengan

sudo apt-get install r-base

Untuk menjalankannya dari terminal, cukup ketikkan :

R

Catatan : R (huruf besar)
Anda akan disodori sebuah lingkungan kerja seperti berikut :

 Type 'q()' to quit R.

Untuk keluar cukup ketikkan :

q()

R-Project ini sangat powerfull, karena paket pengolah statistiknya sangat banyak, baik yang tersedia secara default atau dalam bentuk paket yang dapat diinstall dari mirror R-Cran.
Beberapa screenshot dibawah ini menunjukkan default fungsi yang bisa digunakan di RKward :

Anda juga dapat menambahkan ratusan paket statistik lainnya dari R-CRAN Mirror. Berikut daftar CRAN Mirror yang ada di dunia :

Anda dapat menambahkan repository dari RKward di menu Workspace –> Load/Unload Packages. Jendela dialognya seperti ini :

Anda bisa langsung menambahkan paket baru di kotak dialog yang tersedia, atau jika anda sudah mengunduh paket R-CRAN, bisa juga langsung diupload lewat jendela tersebut.
Jika anda menggunakan versi console anda bisa mengetikkan di terminal anda :

> chooseCRANmirror()

Akan muncul jendela pemilihan paket seperti tampak pada screenshot berikut :

Untuk menambahkan sebuah paket di terminal bisa gunakan perintah :

> install.packages(c("pkg1", "pkg2"))

OK, itu sedikit pengantar R-Project sebagai alternatif pengganti SPSS.
R-Project ini layak menjadi pilihan mahasiswa dan dosen karena jauh lebih powerfull dan lengkap. Dan yang terpenting, dia bersifat Open Source dan Free.
Selamat mencoba
