I am a beginner in R and I have tried to find information about the following without finding anything.
Given a data frame with a column that contains strings. I would like to plot the frequency of strings that bear a certain pattern. For example
I\'ve been doing a lot of research on this topic and I\'m finally getting somewhere. Below is two complex numbers from the java code I\'m using:
I am trying to compute the frequency of a given sound process through the microphone on the iphone. I\'ve read all the post about FFT (including all apple code examples e.g aurioTouch,SpeakHere), but
I hope you can help me with this problem. What I intend to do: Given a right text, I want to count the frequencies for every stemmized token ngrams without the stopwords(in other words, the stopwords
s=array1 #user inputs an array with text in it n=len(s) f=arange(0,26,1) import collections dict = collections.defaultdict(int)
I\'m developing a kind of guitar tuner. I have a function that gives me the FFT, and the values of the FFt for each frequency.
Ok,first post.. So I have this assignment to decrypt cryptograms by hand,but I also wanted to automate the process a little if not all at least a few parts,so i browsed around and found some sed and
Recently I asked this question: How to get the fundamental frequency from FFT? (you don\'t actually need to read it)
I have a set of user recommandations review=matrix(c(5:1,10,2,1,1,2), nrow=5, ncol=2, dimnames=list(NULL,c(\"Star\",\"Votes\")))
