Introduction

This plugin contains some simple features that helping writing R languages:

• Indentation corrections
• Useful commands
• More comprehensive syntax coloring
• Showing functions' parameters in Symbol List (cmd+r)

Indentation corrections

Indentation without braces

It corrects the strange behavior when for, while, if, else and repeat are used without braces. In this situation, original indentation rule does not indent the next line. e.g.:

Original:

for (i in (1:10))
cat('Hello, baby!')

Now:

for (i in (1:10))
    cat('Hello, baby!')

Extra indentation

It corrects the extra indentation in case like:

Original:

if (baby==1){
  cat("Hello baby!")
  } else {
    cat("Hello dady!\n")
  }

Now:

if (baby==1){
  cat("Hello baby!")
} else {
  cat("Hello dady!\n")
}

Comment

Comment does not affect indentation. e.g.,

Original:

for (i in (1:10)){
  1+1
        #it is is comment!{
          1+1
}

Now:

for (i in (1:10)){
  1+1
        #it is is comment!{
  1+1
}
