This question is not at the right place (and down-voted) but for your information you may take a look on Frequency Range of Dog Hearing where you can read that: Humans can hear sounds approximately within the frequencies of 20 Hz and 20,000 Hz […] The frequency range of dog hearing is approximately 40 Hz … Read more
You should never divide by zero. locate two consecutive peaks in column B calculate the time difference between the corresponding times in column A divide 1 by this time difference By the way this is not an Excel issue: 1 solved Divide by zero error when calculating frequency?
if you want to write it in a sorted manner you can do this. from collections import Counter wordlist = open(‘so.py’, ‘r’).read().split() word_counts = Counter(wordlist) write_file = open(‘wordfreq.txt’, ‘w’) for w, c in sorted(word_counts.iteritems(), key=lambda x: x[1], reverse=True): write_file.write(‘{w}, {c}\n’.format(w=w, c=c)) solved Words, sorted by frequency, in a book (.txt file)
There are two problems here. First, while std::string is null-terminated (required in C++11, de facto in most implementations before that), you cannot access past size(). If you used string::at() directly, then you’d get hit: reference at(size_type pos); Throws: out_of_range if pos >= size() which would be true for the null terminator. So the right way … Read more
Try something in the veins of this: library(wordcloud) words <- c(“foo”, “bar”) freqs <- c(10, 3) wordcloud(words = sprintf(“%s (%s)”, words, freqs), freq = freqs) ?sprintf and ?paste might be helpful. 0 solved How to display frequency in wordcloud
