I want to extract the first non-zero digit of any vector, as for example from a<-runif(100,0,1). Tried it using grep (...) but didnīt work.
Any help is very much appreciated. Thanks, Manica
How about:
a <- runif(10, 0, 1)
b <- as.character(a)
nonzero <- regexpr("[1-9]", b)
as.numeric(substr(b, nonzero, nonzero))-sundar
P.S. in the future, it would be helpful to see an example of the output you expect to avoid any confusion in the question.
