func2 <- function(x) which(grepl(x, noquote(nombreL)))
lapply(noquote(nombreC), func2)
Side note: if you wanted the object a in Tal's solution to be a vector,
you could use sapply() rather than lapply(). For this problem, the solution
has to be a list because the position matches are unequal in number
across individuals.
