Create Multiple Folders Using R Codes

Create Multiple Folders Using R Codes

Below codes show how to create multiple folders without leaving R environment. The code chunk is useful when, for example, doing graphical diagnostics for some statistical models and numerous (e.g., several hundreds or thousands) diagnostic plots will be produced.  Multiple plots can be woven into a html file, and visually checked afterward.  

foldername <- read.table(nameList.txt, header=FALSE, sep=".")[,1]
 
for(i in 1:length(foldername)){
 tmp <- foldername[i]
 test <- paste("mkdir ", tmp, sep="")
 system(test)
}

Creating custom shortcodes codes in Wordpress

Creating custom shortcodes codes in Wordpress

If you need some custom shortcodes, you have to add a few lines in your themes function.php file.

First, create the function that you want to use. In this example well just make the text red between [red][/red].

 function makeRed($atts, $string) { 
 return <span style="color: #ff0000;">.$string.</span>; 
 }; 

Next we need to register our function.

 function register_shortcodes() { 
 add_shortcode(red, makeRed); 
 }; 

Finally, we need to make the whole thing work.

 add_action(init, register_shortcodes);
