help with creating a box plot
Have you read "An Introduction to R" ? This is a pretty basic exercise that you should be able to do by yourself if you have. If you haven't, you need to (or some other basic R tutorial -- there are many around). -- Bert On Fri, May 18, 2012 at 10:41 AM, Adrian Johnson

Hi:
I am looking for some help in making two boxplots next to each other.
I have a data like this:
N1 ? T1 ? N2 ? T2 ? N3 ? T3 ? N4 ? T4 ?... Nn ?Tn
7 ? ? 8.2 ? 4 ? ? 5 ? ? 8 ? ?10 ? ?4 ? ? 5 ..... ?10 ? 11
I want to have box plot for all Normal samples (N1,N2,N3,N4,,,,Nn)
and another box plot for all tumors (T1,T2,T3,T4,...Tn).
I have data in a numeric class.
If data is represented as N1 N2 N3 N4 T1 T2 T3 T4 I can do something
like the following:
if x object is my data matrix
boxplot(x ~ c(rep('N',n),rep('T',n)), ylim=ylim, main=title)
since the data is arranged as N1 T1, I don't know how to use boxplot
function on tumor-normal lable.
?Could any one help me please.
thanks
Adrian
