[R] a loop for boxplot graphs

Dear Colleagues

I have the following code that generates a boxplot for one specific labtest:

boxplot.n(LBSTRESN~COHORT, main="Boxplot of laboratory data for XLXXX-XXX test=Creatinine", subset = LBTEST=="Creatinine",
xlab = "Cohort Number",
ylab = "Units = umol/L",

I would like to know if there is a way to loop through the dataset and produce the boxplot for a number of specific labtest.

Looking at the documentation for loops I can't see how I would change the "ylab","main"and "subset"  

Can someone refer me to a similar example in the online documentation?
