[R] P value from jaccard's index matrix

[sreenath]

My table having 40 raw and 4 columns, in that 4 columns first column belongs
to one group and the remaining constitute the other group. using following
commands for calculating jaccard's index
x <- read.csv(file name,header=T, sep= ) 
jac <- vegdist(x,method="jaccard") 
from this out file(jac) how can i find the p value for two groups ? and how
can i plot notched box plot of these two groups? when i use boxes
(as.matrix(jac)~x$first column,notch=TRUE) it showing 40 box plots.why it
so?
