I have been trying to visualize times of lowest tides, month by month. I have tide predictions with times either in unix time or a text format, and heights in feet or meters. I had been able to derive the clock times of each prediction. I would now like to graph this data with points showing heights as "r" and times as "theta", from 0000 to 2355. There is a seasonal

Hello, I hope that you can bare with me. I am new to models, but I think I have a pretty godd understanding of how to run them now, including how to use AICc and Anova. The issue is that I have many factors that I wish to compare so doing each one at a time would take forever. I came across the MuMIn package and I was so excited, however I am getting an error message and i don't know why.

Dear all, I want make correction depth of a bathymetric data set. To do so, I have the depth data set sample every second (a depth at each second) in one hand, and in the other hand, I have a tide variation level data set sample every 250 ms. The time register in each data sets (tide and bathymetric) is express in seconds followinf this format : hh:mm:ss.ss I would like to rectify the depth

Dear R users, It may be very simple but it is being difficult for me. I'd like to calculate the difference in percent between to measures. My data looks like this: set.seed(123) df1 <- data.frame(measure = rep(c("A1", "A2", "A3"), each=3), water = sample(c(100:200), 9), tide = sample(c(-10:+10), 9)) df1 # What I want to calculate is:

Hi R folk, I have a time series of scalar downstream velocity data measured across a tidal channel. The variables are the locations in bins across the channel, the samples are over time. The fluctuation over the tide cycle is an enormous fraction of the time variation in the data ... 96%. The spectral energy of the tide is concentrated in a couple bands that make up the major constituents of the

Hello, I have been attempting to set up a lme and have looked at numerous posts including 'R's lmer cheat-sheet' as well as reading a number of papers and other resources including R help, but I am still a little confused on how to write my model (I thought I had it). I have asked a number of questions on different forums; most of which have been resolved. My main concern right now

Hello all, If someone could take a little time to help me then I would be very grateful. I studied piping plovers last summer. I watched each chick within a brood for 5 minutes and recorded behaviour, habitat use and foraging rate. There were two Sites, the first with 4 broods and the second with 3 broods. http://r.789695.n4.nabble.com/file/n4511178/Table_PP_Maslo_et_al.png As the data within a

I''ve tried 0.11.4, and it has not yet crashed, even after I removed (most of) the workarounds. However, the same is also true of 0.11.3... I haven''t seen any of these crashes for several days, which is a very good thing. I can''t remember all the workarounds I did to sidestep the crashing; some of them I don''t want to reverse because they actually were also

Hello, My tests are messing with one another because it seems that they aren''t cleaning the database after execution. I have the tables headlines and articles. And the articles table has a foreign key to the headlines table. My schema structure is created by this script ---- drop table if exists changes; drop table if exists articles; drop table if exists headlines; create table

We have a third party mail system which can write/read accounts to/from AD using ldaps protocol, it works fine with active directory of windows server 2003. When I test the mail system with samba4 DC, I can't disable user from the mail system, because the mail system write 0x800002 (8388610,UF_ACCOUNTDISABLED | UF_PASSWORDEXPIRED) to userAccountControl field of AD/samba4, and samldb returns

I must apologize in advance for asking a simple question. I am sure that a clue will be sufficient to get this show on the road. I am trying to graph tide prediction data in various ways. I haven't been able to answer this question after pouring over TFM. I read the datafile theight <- read.table("tides",header=TRUE) I do get a summary() or fivenum()

I am having a series of problems using date time data that has been converted into a POSIXt and POSIXlt classes. I have hourly time series data from 1900 that has been converted from text data. I assume most of my problems come from a mis-underdanding of the POSIX class. My matrix named (aa) for this year is approx 8700 by 4. When I try to calculate the length of posit column ( which is the

Does anyone have the C reference code of the ITU G.711 Appendix II ? -- Guilherme Loch G?es "Wave after wave will flow with the tide And bury the world as it does Tide after tide will flow and recede Leaving life to go on as it was..." - Neil Peart , Natural Science

Hi, Two questions: 1 - Say I have average speed and directions for tide and I would like to plot them on a polar plot, but with different colors so I can indicate the two directions. I'm using polar.plot from the plotrix library. How can I add a second "b" and "dir.b" series to a polar.plot? library(plotrix) a = 3 dir.a = 85 b = 4 dir.b = 250 polar.plot(a, dir.a, start =

List, A recent discussion over on XiphWiki is trying to decide if OggPCM should support only little-endianness or the usual combo of big and little. It started with the following statement by an user (Qqq): "Portable players are usually ARM, which is usually little-endian. The Macintosh is now little-endian. Obviously the PC is little-endian. Clearly there is a winner. It's long past

To stem the tide of support requests from people who don't read the INSTALL file when installing OpenSSH and then complain about password auth failing. I am considering the idea of automagically installing a PAM file into /etc/pam.d if it exists, PAM support is enabled and no such file already exists. I have a couple of questions: - How is PAM controlled on Solaris? Is there a pam.d

I am in the process of converting from Matlab to R, but a major sticking point for me at the moment is accessing data via OPeNDAP. After several hours of searching, I found that other people have discussed this functionality in the past, but it does not appear to have yet been developed. One programmer, Luke Miller, has managed a work-around by downloading ascii data from an OPeNDAP site (

We're being ping-flooded by the Nachi worm, which probes subnets for systems to attack by sending 92-byte ping packets. Unfortunately, IPFW doesn't seem to have the ability to filter packets by length. Assuming that I stick with IPFW, what's the best way to stem the tide? --Brett Glass

The Register is carrying a article written by Kevin Poulsen of Securtiy Focus, calling asterisk "..the most powerful tool for manipulating and accessing CPN data.." > http://www.theregister.co.uk/2004/07/07/hackers_gut_voip/ I hope NuFone doesn't drop asterisk-set-able callerid's after this article; i've been wanting that feature from voicepluse for a long time.

Hi R-listers, I am having trouble plotting the values for the R2 line, lowess smooth, smothered conditional spread, outlier identification. I have tried the function text and legend but was unsuccessful. Please see below. Your help would be appreciated. Thanks in advance.
