Dear R-users, I have a dataset as like below, and I want to subtotal the values of rice,wheat and maize by year for each fid. fid      year     rice     wheat      maize ------------------------------------------------ 1        1995      5        NA           NA 1        1995      NA        3           NA 1        1995      NA       NA           2 1        1996      4        NA     ...

Hi, I asked a few questions about the flac format a couple of weeks ago. One more (if you don't mind) about the Rice coding. The Rice parameter "k" can't be zero (unless I'm mistaken), yet the FLAC spec says the Rice parameter can range from 0 to 15. I guessed, and tried adding one before using the parameter (i.e. assuming the range was really 1 to 16), and that didn't fix it. How should I...

Hi R Users, When I use package lme4 for mixed model analysis, I can't distinguish the significant and insignificant variables from all random independent variables. Here is my data and result: Data: Rice<-data.frame(Yield=c(8,7,4,9,7,6,9,8,8,8,7,5,9,9,5,7,7,8,8,8,4,8,6,4,8,8,9), Variety=rep(rep(c("A1","A2","A3"),each=3),3), Stand=rep(c("B1","B2","B3"),9), Block=rep(1:3,each=9)) Rice...

Dear all, Apologies for this beginner's question. I have a variable Price, which is associated with factors Season and Crop, each of which have several levels. The Price variable contains missing values (NA), which I want to substitute by the mean of the remaining (non-NA) Price values of the same Season-Crop combination of levels. Price Crop Season 10 R...

...lly unreasonable, because using them very greatly increase the encoding time. But I did some tests and found that using "-r 8" instead of "-r 6" NOT greatly increase the encoding time (one of my tests: 24 sec instead of 18 sec for 10 min input on my machine). Increasing value of Rice order is not exhaustive, and increasing encoding time is predictable. IMHO 33% (for calculation sample of 100 tracks was used) is not critical for "best" compression preset. People use "best" preset and expect to get "best"/"highest" results. It is basis of e...

Hi all, I am interested in building a stand alone Rice Encoder/Decoder, using FLAC source code as a starting point. I've read the theory behind it, and I am very interested in info theory. However, I am struggling with how exactly I would implement the theory in code. I'm a newbie to computer science (only 1 year experience). I have read th...

Going in details through the FLAC format specification, I realize that there are 2 rice coding methods now supported for residual encoding. I thought I remembered in the 1.1.3 times that there was only 1 method (with 4-bit Rice parameter) [or was I drunk ? ;-)]. Going through the change log, I didn't find any reference to such an addition to the format. Now, the decoder implement...

And there > are the following comments in stream_encoder.c: The residual is stored as a Golomb/Rice code. As far as I know, that is not limited to 32-bit in the format itself, only in the implementation. However, there are two residual coding methods now: rice and rice2. rice2 was added when it turned out rice (with a 4 bit rice parameter) wasn't able to cope with the larger residuals t...

Hello ! The following algorithm describes Golomb(=Rice?) encoding: http://en.wikipedia.org/wiki/Golomb_coding#Simple_algorithm What is unclear to me is how many audio samples encoded with a fixed parameter (denoted 'M' in the wiki, which i presume is equivalent to the 'Rice parameter' invohed here): http://flac.sourceforge.net/document...

hello, I am now develloping an embeded decoding system for flac.I have a problem about the format of the rice coding: the residual begins with : 01 01 08 0C the first two bytes are the warmups, the prediction order is 2. and the 080C is the following: 00 0010 0000 001100 the first two bits mean: residual coding method is partitioned rice the following four bits mean: the partition order is 2 ; the follo...

Hi all, Someone over at Hydrogenaudio pointed me in the direction of this 'bug' report: http://sourceforge.net/p/flac/bugs/352/ I don't know what Josh was thinking (look at the comments section) but AFAIK it's just a documentation thing, maybe he confused partition order and rice parameter? Anyway, here are two patches that should 'fix' this. -------------- next part -------------- A non-text attachment was scrubbed...

I have data on area under cultivation of a crops for 17 states..I need a scatter plot to be made for the following assignment Read the data file /Data/ep602/areas.csv, and make a scatter plot that displays area under rice in 1960s on the x axis, and percentage change in area under rice between 1960 and 1990 on the y axis. Let origin of the plot be at (50 per cent of area of rice in India as a whole,percentage change in area of rice in India as a whole). Then label with name of State three highest/rightmost points an...

I have a doubt reg. RESIDUAL_CODING_METHOD_PARTITIONED_RICE2 http://flac.sourceforge.net/format.html#partitioned_rice2 tells that 5 bits are used to specify the Rice parameter. And "Escape code, meaning the partition is in unencoded binary form using n bits per sample; n follows as a 5-bit number" Question: What is the use of the "escape c...
