...(countries, function(x) x %in%
euro)))
data1[EMU==TRUE,13]
a<-table(EMU)
3.1.2. Are the member and non-member country-pairs alike?
What I need here is:
I want to find the mean of avgflow, but only for the data where 2 countries
are in the euro vector/if EMU=TRUE ?
I have tried with:
>avgflowONLY<-cbind(avgflow,EMU)
> NEWavgflow<-rep(0,nrow(avgflowONLY))
> for (i in 1:nrow(avgflowONLY)){if
> (EMU==1){NEWavgflow[i]<-mean(avgflow[i])}}
BUT it gives me:
Warning messages:
1: In if (EMU == 1) { ... :
the condition has length > 1 and only the first element will be use...
