[R] quantmod: How could I change the name in chartSeries

hi, guys, I am just a beginner to the excellent R package, quantmod. I quite don't know how to change the y-axis name in the chartSeries function. Actually, I want to write some sort of the following function, by which I could use just one code sentence to complete the financial analysis.
