#Plot result of for loop in r how to

Lately, answers on stackoverflow have over-emphasised speed. They also tend to prevent bugs because they eliminate the book keeping code needed with loops. The point of the apply (and plyr) family of functions is not speed, but expressiveness.

HereвЂ™s what the master, Hadley Wikham has to say about expressive code and the apply family: They make your code more expressive and in turn easier to read: There are several good reasons to use the apply family of functions.ДЎ. So, for example you can use the lapply function (list apply) on the list of file names that you generate when using list.files(). However if you want to scale this automation to process more and / or larger files, the R apply family of functions are useful to know about.ДЄpply functions perform a task over and over - on a list, vector, etc. For loops are a good start to automating your code.

In the previous lessons, you learned how to use for loops to perform tasks that you want to implement over and over - for example on a set of files.

You will need a computer with internet access to complete this lesson.

Use the lapply() function in R to automate your code.
