Examples

x <- setNames(object = c(0.2, 0.3, 0.4, 0.1), nm = letters[1:4])
check_init(x) # x is a valid input, no warnings issued

x <- setNames(c(0.2, 0.3, 0.4, 0.1), nm = c("H", NA, "NA", "D"))
check_init(x) # Should issue a warning about missing names

x <- c(-2, 0.3, 0.4, 0.1)
check_init(x) # Should issue a warning about a value below 0 and about not summing to 1
