什麼是 R ?

開源“lingua franca”

Analytics, computing, modeling

Global community

Millions of users 7,000+Packages

Big dataEcosystem

Scalability

CRAN: The Comprehensive R Archive Network

Open Source “lingua franca”

Analytics, Computing, Modeling

In addition to CRAN, Bioconductor, GitHub, and others distribute R packages

大量人才知道如何使用

為什麼 R ?

可擴充正在進行計算的資料

更容易保護重要的資料

角色使用創建效率

$?

開源R的挑戰

Uncertain total cost of ownership and return on investment

Integrating R with existing and ever changing data infrastructures

Scale and Performance

Data movement restricts access for efficient data modeling

Big Data In-memory bound Hybrid memory & disk scalability Operates on bigger

volumes & factors
