This looks really ugly but it 'may' do what you want. I was too lazy to
generate enough raw data to check. Note i changed the names in x as they were
a bit clumsy.
x <- data.frame( id = c(1,2), Event1= c(1,0), YEvent1 =
c(68.25,0), Event2 = c(0,1), YEvent2 = c(0,68.5))
y <- data.frame( id = c( rep (1,5), rep (2,5)), Year=c
(68.0,68.25,68.50,68.75,69.0))
y $ Event1 <- c (0,1,1,1,1,0,0,0,0,0)
y $ Event2 <- c (0,0,0,0,0,0,0,1,1,1)
x <- data.frame( id = c(1,2), Event1= c(1,0), YEvent1 =
c(68.25,0), Event2 = c(0,1), YEvent2 = c(0,68.5))
dd <- melt(x, id= c("id", "Event1", "Event2"),
value.name="year.quarter" )
dd1 <- subset(dd, dd[, 5] != 0 )
dd1 <- dd1[ , c(1,2,3,5)]
