[R-meta] extract pval from robust function

Hi Wolfgang,

Thanks for your answer, it works.

One more thing, using the dat.konstantopoulos2011 example, I asked for the fitstats of res. I need to extract the AICc value, i.e. 23.3; how can I do it ? Also, I assume that those fitstats data are valid using the robust function results; are they ?

> fitstats(res)
logLik:   -7.24
deviance: 14.48
AIC:      22.48
BIC:      30.44
AICc:     23.30

Thanks in advance, 

Roger ☺

Hi Roger,

robust(res, cluster=dat$district)$pval[2]

Use str() to find out about the structure of an object, so:

str(robust(res, cluster=dat$district))

Scanning through all that stuff will often lead to the answer.
