hello is it wrong with this expression: subset(dfpr2_r,(as.numeric(as.character(dfpr2_r$pr2))) > 0.2 && (dfpr2_r$landa
10))
it gives nothing regards -- Open WebMail Project (http://openwebmail.org)

I would suggest that first you look at the results of
(as.numeric(as.character(dfpr2_r$pr2))) > 0.2 && (dfpr2_r$landa > 10)
by itself. Does it give all FALSE ?
Then look at each of the parts separately. What are the results of
(as.numeric(as.character(dfpr2_r$pr2))) > 0.2
and
dfpr2_r$landa > 10
Are there any TRUE among the results?
Does
as.numeric(as.character(dfpr2_r$pr2))
give what you expect?

I'd guess the problem is using && instead of &. Duncan Murdoch
