histogram with user defined function in R

Question

Suppose I have written a user defined function to create a histogram:

sunny <- function(x,nadia) {
attach(nadia)
hist(x,  main="x", col="sea green", border="white",breaks=100)
}

Now my problem is I would like to have the variable name displayed on the graph, which is not appearing. I tried with the main = option but is it is showing only the character x since it is in quotes. I would be really glad if some one could solve my issue. Thanks!

Indirectly your question can be answerd by use of the answer on the following stack overflow question:How to convert variable (object) name into String

Applied in your situation results in the following code:

sunny <- function(x,nadia) {
attach(nadia)
hist(x,  main=deparse(substitute(x)), col="sea green", border="white",breaks=100)
}

This may be correct answer to the question but you should add some clarifications to it. Simply posting a code snippet without any explanation is not considered good practice here on Stack Overflow. – Marko Popovic Apr 28 '16 at 11:57
