similar to: Plotting monthly maps from yearly data

Sorry, this is my first time to post. I have a big data set: first colume is date (ex: 2008-2-150, the second is time (10:30:00), and the following columes are variaty measurement data. Every 30 min, I have one data. I want to find an effecient way to calculate the hourly, daily, monthly and yearly average, and plot them, and eventually use these average data to do further analysis. Thanks!

I have searched the forums but I am having trouble trying accomplish two specific plots. I am not sure if this is a very basic task but I am having a lot of trouble Here is my data frame: date prod_daily price 1 2003-08-15 12050 4.83 2 2003-08-18 12050 4.94 3 2004-08-10 12300 5.78 4 2004-08-11 12300 5.64 5 2004-08-12 12300

I have two different datasets 1) is in monthly format (obs) 2) yearly format (model) in obs I have 84 files ( 2003:2009)for different months & in model I have 4 different files which has yearly data (2005:2008) So for calculating my requirement I need these both data sets. The sample calculations are as follows file_o<-list.files(path=' ', pattern="0.2.text") #

It would be great to get some idea of what chips and DSPs people have tried to compile Speex for, and what success they've had. So, if you've tried Speex on a chip, could you take a second to fill in the following and post it to the list? Chip Name: Speex Version: Floating or Fixed: Encode, Decode, Both or Simultaneous: MIPS (if known): Other comments: Many thanks, Gerv

Hi, I want to take a .wav and generate a bytestream that I can feed direct to speex_decode(). The speexenc program appears to produce it wrapped up in an ogg stream, and it doesn't have any sort of "raw" mode. I've tried hacking on it to remove the ogg parts, but I must have got it wrong, as my decode dies after decoding 160 bytes (which I believe is one frame) with an

Hi all, I am plotting a financial time series, but I need a more detailed X-Axis. Example: x <- zoo(rnorm(1:6000), as.Date("1992-11-11")+c(1:6000)) plot(x) The X-Axis is labeled "1995", "2000" and "2005". I would need either "1995", "1997", etc. or maybe yearly I used google first, then look at "?plot.zoo" but

I have sent the visual studio project files that compile the speex client to jean-marc directly (as an attachment), sometime this week, I will also upload the binary builds of static library files to my site www.phonestack.com. I am porting our LTP (lightweight telephony protocol) to some embedded systems. I require to run speex in an environment that doesn't support memory allocations. How

Hope someone can help me here. I have a daily time series, say 2003-02-01 2003-02-03 2003-02-07 2003-02-09 2003-02-14 .......... 2004-02-01 2004-02-04 0.4914798 -1.1857653 -1.6982844 -0.3559572 -0.2333087 ........... 0.44553 -0.45222 I need to calculate the statistics for the overlapping rolling yearly window with rolling step as 1 day so for each of the intervals: (2003-02-01 ~

Dear R-experts, Sorry if I've overlooked a simple solution here. I have calculated a proportion of the number of observations which meet a criteria, applied to five years of data. How can I break down this proportion statistic for each year? For example (data in zoo format): open high low close hc lc 2004-12-29 4135 4135 4106 4116 8 -21 2004-12-30 4120 4131

Hello, I have weight and wing length data of 5 kinds of birds (B1 to B5). Weight data (predictor) and wing data (response) were used to generated a simple regression. (using lm) Now some weight data are found but without wing data (B6, B7). I want to use the generated simple regression to produce wing data of B6 and B7 by their weight data. Please kindly advise R code to carry it out. Thank you.

Will it definitely work, definitely not work, or might it work and no-one has any idea? :-) More specifically, I'm trying to decode Speex data encoded using sampleenc. So, it's definitely been encoded

Hi everyone, In the 1.1.x branch, I've kept adding more stuff to libspeex: preprocessor, AEC, etc. I'm now considering moving all those to a separate library (libvoip, libspeech, whatever). Anyone on this list has good reasons I should consider for either splitting or not splitting libspeex? Cheers, Jean-Marc

I do not want huge online mailboxes, as doing offline, rotating data backups could then take forever (among other reasons). I would rather avoid online (cloud) backups (data protection etc.). If I
