Flag aggregation by the frequency count method

1	flag_frequency(f)

`f`	A vector of flags containing the flags of a series for a given period.

flag_frequency returns a character with a single character flag in case the highest frequency count is unique, or multiple character in case there are several flags with the highest frequency count.

flag_frequency(c("pe","b","p","p","u","e","d"))
flag_frequency(c("pe","b","p","p","eu","e","d"))


flags <- tidyr::spread(test_data[, c(1:3)], key = time, value = flags)
flag_frequency(flags[,5])
apply(flags[, c(2:ncol(flags))],2, flag_frequency)
