search for: correlogram

Hello group, For my PhD I'm working on a spatial sampling grid. I do have two data sets which I'd like to compare using cross-correlograms or cross-variograms. Is this an option in one of the R-packages? I've been searching the R-help archive and the available package-documentations, but I can't find how to do this. Thanks in advance, Ren?. _______________________________________ Ren? Eschen CABI Bioscience Switzerland...

Dear all, I'm using the correlogram function in the spatial library to calculate spatial correlograms of radar data. However, I'm finding that the resulting values are often outside the range [-1,1], usually only at larger distances of separation. I'm not sure whether to be overly concerned about this, or dismiss it as some...

I would like to make a correlogram in which I also have a correlation matrix instead of one of the panels. Is that possible? -- View this message in context: http://r.789695.n4.nabble.com/Correlograms-tp4283245p4283245.html Sent from the R help mailing list archive at Nabble.com.

Dear all, I generated a Correlograms and used the panel.ellipse (confidence ellipse and smoothed line) option. Is there a way to get instead of the smoothed line the linear regression?

Hello, I have time series and need to draw simple and partial correlograms with associated Q-statistics (the same as in EViews). Can I do it in R? Thanks --------------------------------- [[alternate HTML version deleted]]

Dear all, I've tried an lm model. I want to check indepence of the residuals, so I was trying the following: library(ape) plot.correlogram(residuals(model1)) I obtain this error: Error en x$p.values : $ operator is invalid for atomic vectors Any idea?

Hello, I am trying to plot a few correlograms on the same figure, with the function corrgram() from the package corrgram. However, the function does not seem to use the base graphic system, as setting out the multiple figure layout with, e.g., par(mfrow=c(2, 2,)) does not work. Does anybody know a workaround for this? Many thanks in advanc...

Hi, I would like to use acf.plot on a correlogram that is computed externally. In other words, I would like to "fake out" the acf object. Is this possible?-- any help would be appreciated. TIA Martin

Hi, I'm doing cross-correlation correlograms with the ncf package. I have four study sites ; four correlograms. I'd like to get the same y scale for the four of them... only, using "ylim=c(-1,1)" does not change the y scale never and I don't know why. I tried with plot() too. Is there another option to change the ylim in...

...ed on the distances in the distance matrix (i.e., I need to select all pairs of points that occur 0-25 m from each other, 25-50 m, etc...). Does anyone have code or a detailed procedure for subsampling or dividing a dataset into distance classes for moran¹s I (or mantel test)? I know there is sp.correlogram but I need significance values for each I value and I need to use distance lags, not lags of number of polygons. Any suggestions would be appreciated.

Please see that correlogram for a arbitrary time series : acf(zooreg(rnorm(39), start=as.yearmon("2008-01-01"), frequency=12)) What is the meaning of lag 0.2, 0.4, ........ in the plot? Those should not be integers? Or I am missing something? Thanks -- View this message in context: http://n4.nabble.com/Meaning-o...

Hi everybody, I want to download the spatial library but I don't find it at the CRAN list package. Where can I find the package ? I have to download it to use the function correlogram.

Dear all, I am trying to avoid a for loop here and wonder if the following is possible: I have a data.frame with 6 columns and i want to get a cross-correlogram (by using ccf) . Obivously ccf only accepts two columns at once and then returms a list. In fact, with a for loop i?d do the following for (i in 1:6) { x[[i]]=ccf(mydf[,i],mydf[,6]) } Is there any chance to the same with lapply? e.g. lapply(mydf,"ccf", .... ) with ... respresentin...

...ld do a histogram of newcar to show the frequency each type of car is bought. If there are 5-10 car types, that works. If there are 50-100 or more, the legend gets illegible. I could also do a histogram of oldcar to see what people gave up, but that's less interesting. I'm considering a correlogram using the corrgram package, but a heat map might work, too. Any tips on making the legends useful in any of this? Any better approaches to try? I tried table() and prop.table() to see if I could get transition probabilities as if this were a Markov chain, but dim() comes out 108 78, which is stil...

...ng on the distance that the factor extends to; so for example the 9000 dist is the largest in the example so should fill the slice, a distance in this plot of 4500 would fill halfway up the slice. I also want to be able to specify the colour of each slice so that I can relate it back to the spatial correlograms I have. I have added some sample data below. Thank you for reading my post, All help is greatly appreciated, K sample data: #distance factor extends to dist<-c(5000,7000,9000,4500,6000,500) #direction angle<-c(0,10,20,30,40,50) #list of desired colour example, order corrisponds to asso...

Hi there, What is the best way to get a time series of daily stock price observations into R (from excel). The time series are daily but there are spaces for w/e's and holidays etc. So I am not sure a ts object will be suitable but I am not sure what I should use? What ever package you recemmned i need to be able to run a corrolelagram. Thanks Hugh -- View this message in context:

...the amplitude of that frequency when the bone is loose, medium to tight (referring to the tension of the reamer/chisel creating a cavity for the hip replacement).? I'm coming at this more from a sound perspective so I would really appreciate some advice from anyone with a handle on stats, could correlograms be used in presenting this data? When working with a large number of bone samples, can anyone recommend a good method of recognizing and mapping these changes? All the best,? Bob
