Try this (convert the logical TRUE to the value 1):
> EvHint<-c(0, 0, 0, 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 0, 0, 1, 0, 0)
> MinTex<-c(0, 0, 1, 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 0)
>
> RiskTest <- (EvHint == 1 & MinTex == 1) + 0L
> rbind(EvHint, MinTex, RiskTest)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11]
[,12] [,13] [,14] [,15] [,16]
EvHint 0 0 0 1 0 1 1 0 1 1 1
1 1 0 1 0
MinTex 0 0 1 1 0 1 1 0 0 0 0

RiskTest 0 0 0 1 0 1 1 0 0 0 0

[,17] [,18] [,19] [,20]
EvHint 0 1 0 0
