New (RMarkdown) post from OS X 10.10 (Yosemite)

This is my first post on OSX 10.10 (nick name: Yosemite). Yep I always late…

As I did mostly, I blog using RMarkdown. It allows you to manipulate your source file in to a structured text and convert it to almost any formats: odt, docx, pdf, html, etc.

Basically you can make any docs containing:

  • outline
  • bullets and numbering
  • basics formatting:
    • make it bold = bold,
    • or italic = italic,
    • even make an superscript symbol = superscript and off course subscript subscript ,
    • strikethrough
    • write equations: $ Q = CA(dh/dl) $
    • insert a link: DasaptaErwinBlog
    • insert a figure: itb_logo
    • insert a quote or lines of code: quote from Einstein
    • insert a table:
Name Age (ya)
Rex 65,000,000
Mankind 100.000
me 39
wife 35
Radit 8
Bila 4
- make a chart out of it
Name <- c('Rex', 'Mankind', 'Me', 'Wife', 'Radit', 'Bila')
Age <- c(65, 0.1, 39, 35, 8, 4)
df <- data.frame(Name, Age)
plot(df, main="Age comparison", xlab="Species", ylab="Age (mya)")

Rplot01
  • and a whole lot more

Another good thing is you can built the entire doc in plain text (ASCII). So it’s:

  • light weight: in kb
  • connected to any word-processor:
    • Libreoffice
    • MS office
  • or text-editor:
    • notepad
    • wordpad
  • virus-free

About the author

My current focus is how to provide the hydrostratigraphy of volcanic aquifers in Bandung area. The research is based on environmental isotope measurement in groundwater and morphometry. My work consists of hydrochemical measurements. I am using multivariate statistical methods to provides more quantitative foundation for the analysis and more insight into the groundwater behavior, especially its interaction with surface water. I use open source apps like R and Python to do the job. In my spare time, I also have a side project to promote open science in Indonesia's research workflow. One of my current focus is promoting INARxiv, as the first preprint server of Indonesia (osf.io/preprints/inarxiv) and serving as ORCID and OSF (osf.io) ambassador. Research interest: Hydrochemistry, multivariate analysis, and R programming. Blog: dasaptaerwin.net, derwinirawan.wordpress.com. (https://orcid.org/0000-0002-1526-0863)
