[R] Plot Moran's I

Hello all,
I'm a new user of R and I have used the spdep package to calculate Moran's I estimates. I used the dnearneigh() function and moran.test() function and obtained what I wanted, but now I want to plot my results with the p-values. I regrouped my results for the Moran's I like
>m=c(m1$e,m2$e...) #m1 contain the results of the moran.test for lag1
>p=c(m1$p.v,m2$p.v...)

The problem is that in mx$e there are three values (moran'I statistic, expectation and variance) and when I plot my results I plot all the three values for each lag. What should I do to choose only the statistic for plotting and maybe the variance for each I statistic? (For the p-value it's ok I have found how to differentiate the significant and non significant values.) I hope someone understand my question and could help me! Thanks a lot.
