[R-meta] extract pval from robust function

Dear list members,

In this example, the p-value of year in the robust function is 0.5885; what are the codes to extract that p-value ?

dat <- dat.konstantopoulos2011
res <- rma.mv(yi ~ year, vi, random = ~ 1 | district/school, data=dat)
robust(res, cluster=dat$district)

Thanks in advance.

Roger :)
