All,
I am looking to find the first principal payment date on structured MBS cash
flow. I am testing the below to make into a function the correct index is
returned. I am a little unsure. Is this the correct way to think about this
problem or is there something already in R that can help?
Glenn
data <- as.list(c(rep(0, 20), rep(1, 340)))
f <- function(x){x != 0}
which(sapply(data, f ) == TRUE)[1]
