Thanks for the answer. I found that smth like below works

subset <- c(1,0,0)
series <- c(1,1,1,0,1,0,0,1,1,0,0,0,0,1)

subset1 <- paste(subset, collapse='')
series1 <- paste(series, collapse='')

xx <- gregexpr(subset1, series1, fixed=TRUE)
as.numeric(xx[[1]]) ## yields the first element numbers in series
[1] 5 9
