Hi, I have had a look around the forums and I can't seem to find anything that works with my data. I have lats, longs, time, tidal speed and direction and need to plot this in an xy plot to determine changes over time. contour and cloud have been recommended to me as a way to do this but I can't figure out how to get 5 dimensions into this. I want lat and long as my x and y, time as my

Hi! I have written an R-package (http://tocsy.agnld.uni-potsdam.de/wavelets/index.html) in R 2.4.1 that requires the ts() function. Users using R 2.5.0 now have a problem installing this package. I checked the package using R 2.5.0: _______________________________________________________ * Installing *source* package 'sowas' ... ** libs gcc -std=gnu99

Dear, I am using "cwt "function from Rwave package to perform Morlet wavelet analysis. d1<-c(1.31673209591515, -0.171333455797346, -1.67618546079420, -0.931604651010362, -0.954614183224057, -1.19821794547758, 0.516096363353144, -0.0432811977638559, 0.737764943619919, 0.438046629673177, -0.208607167908743, -0.3091308821262, -1.42473112931594, 0.234125312118165, -0.307047554490597,

I am porting some FORTRAN to R in which an Inf triggers an if(). The trigger is infinite on exp(lgamma(OVER)). What is the canonical R style of determining OVER when exp(OVER)== Inf? The code structure that I am porting is best left intact--so I need to query R somehow to the value of OVER that causes exp(lgamma(OVER)) to equal Inf. On my system, exp(lgamma(171)) is about first to equal Inf.

Trying to use rcmd in our Windows environment to launch tasks on remote servers. We are using the job scheduler from Tidal corporation. The problem is the return code that's coming back to the job scheduler,Tidal, is from the RCMD NOT from the tasks that it launched. We need to get the return code from the task that was launched via rcmd. Help Lou Zollo Production Control Manager

I am looking for some explanations about the usage of the poorely documented R paclkage Rwave. Has anyone ever tried out its functions for Wavelet Analysis ? Thank you so much.

Dear list, I am trying to choose the scale parameter for the cgt transform but I don't know how to do it. In time I would like to be able to separate points 30 samples apart, and in frequency I would like to separate bands 0.04 Hz apart. I tried the two approaches described below and they gave me different results. I would appreciate advise on how to do this. The Rwave Gabor transform uses

Dear helpers, When I use the function cgt of library Rwave, the time axis of the plot is always on the [0,1] scale regardless of the original time. This happedn when I tried to reproduce some pictures of "Practical Time-Frequency Analysis", e.g. Figure 3.5 and 3.6 using the codes provided in the book. But the figures of the book display the real sampling time using the same codes.

Hello, I would like to be able to plot an array on a plot, something like: |arg1 | arg2 | arg3 val1| 0.9 | 1.1 | 2.4 val2| 0.33 | 0.23 | -1.4 val3| hello| stop | test I know Rwave is good to report but don't want to use it. ? Is there a package that allow quick and dirty plot of dataframes like this ? Thanks a lot -- View this message in context:

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

Hi, Could someone please suggest where I might find some instructions / tutorials / FAQs that describe how to create a frequency distribution and cumulative frequency distribution in R using different class withs. I have about a 2-million observations (distances between points ranging from sub-millimetre to about 400km, and I want to get a feel for how they are distributed). I'd like the

Hello R users, I am trying to use R to do the low pass filter analysis for the tidal data. I am a novice in R and so far been doing only simple stuffs on R. I found a package called signal but couldn't find the proper tutorial for the low pass filter. Could anyone point me to the proper tutorial or starting point on how to do low pass filter analysis in R ? Thank you so much. Janesh

Dear all, I wanna to do multiple comparison test for proportions (multiple chi squre ?), could someone tell me how in R, thank you!

CRAN et al., I would like to add an extented introduction or other arbitrary sections to my package lmomco. I have been shipping inst/doc/Introduction.Rd. I would like to have this content inserted to the front of the PDF build for the CRAN. The R-exts.pdf seems to be a little silent on this subject? For my purposes, I have been doing this R CMD Rd2dvi --pdf

QUESTION: is there a way to make objects (e.g. data frames) read-only? BACKGROUND: I am writing some functions that use a data frame (frequencies of tidal constituents) that I want to be read-only. I can see how to accomplish this within a single function (just define the data in the function), but I'm not sure how to share read-only values between (un-nested) functions. Is there a more

You should be able to use that header information to create the correct parameters to the read_fwf function to read in the data.

Dear all, Before I can get into serious Fourier analysis of Radon time-series I am practising with 24hour and 24.8hour sinusoids to assist with my interpretation of signals ittributed to tidal input to Radon time series. I am stuck. I have tried researching this to no avail. I am awating a book that should describe fourier transforms in detail and another one that should discuss the R

Hi , I know this question has been asked twice in the past but to my knowldege, it still hasn't been solved. I am doing a zero inflated binomial model using the VGAM package, I need to obtain p values for my Tvalues in the vglm output. code is as follows > mod2=vglm(dmat~Season+Diel+Tidal.phase+Tidal.cycle,zibinomial, data=mp1) > summary(mod2) Call: vglm(formula = dmat ~ Season +

Dear All, I am a novice when it comes to time-series analysis and at the moment I am actually interested in calculating the Hurst exponent of a time series. This question has already been asked quite some time ago http://bit.ly/98dZsi and I trust some progress has been made ever since. I was able to find some functions in the packages http://cran.r-project.org/web/packages/Rwave/index.html
