R adalah satu programming language yang digunakan untuk statistical computing and graphics. Kalau masa belajar dulu, kami statistics student diperkenalkan dengan R, SAS dan Minitab.
Untuk belajar R ni pun bermula dengan C++ programming.
Bila dah masuk kerja pulak, bos asked me to do/study something that I have never done before. Study rmarkdown. Rmarkdown ni just kita nak turn what we do in R into document or preview in browser. Sekarang ni aku guna RStudio. Dia lagi wow dari R yang biasa guna. Tapi kalau nak guna RStudio ni kena download juga R. RStudio ni ada jugak certain package yang tidak boleh kita dapatkan. That is why kena update R kepada yang latest.
Sejak masuk dalam alam kerja ni, aku banyak main dengan pivot table. Pivot table ni one of powerful function dalam excel. Pivot table ni membantu kita dalam extract data into columns and rows in one table and we can make it in graphics as well. It helps us to filter all the needed things or terms for our analysis. There is a lot of function that we can do further, just need to learn more and more.
Guna pivot tabel ni buat kita lagi nampak untuk setiap terms, variables, it can count automatically, helps us to produce the conclusion faster and more.
And back to the main title of this entry, R also allowing pivot table function. With RStudio it is much more nicer.
Okay, if nak tahu more about rmarkdown cklick here.
