Hi, I want to model different timeseries with ARMAX models in R because I think that ARMAX models will map best to these data. Besides I don't want to use the order of the AR or MA part but the lag e.g. AR Part =ar1, ar2, ar7; MA Part =ma1, ma3 and I want to use exogenous variables as well. I coudn't find any solutions in the R help and therefore I want to ask all of you. Does anyone

hi, i am running R with JGR and Deducer under Ubuntu Mint Lucid. since i updated to R 2.12 i can no longer make graphs - R just crashes. the full error report was posted to launchpad (https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/675905) without any success so far. anyone with a similar problem or helpful suggestions? thanks! kat

hi all, after fitting a multiple linear regression model <- lm(y ~ a + b+ c+d) i wanted to plot diagnostics plot(model) but get the error message Error in object$coefficients : $ operator is invalid for atomic vectors. which does not make a lot of sense, since there is no "$" - i am working with an attached dataset. can anyone help, please?? thanks a lot, kat

Hi, how can I use rm() on objects named like: paste("site",i,"_data",sep="") while looping through i? I tried rm(paste("site",i,"_data",sep="")) but I get the error that rm() must contain names or text strings which is confusing me as I thought paste() would create something like that...? Thanks, Katharina -- Time flies

Hello, What options are available for me to debug my R scripts? For example I normally do something like >source("myfunctions.R") >function1("height", "weight") myfunctions.R is a large R source file that contains many functions. function1 is the "main" function in myfunctions.R. It calls many other user-written functions that are also in

Now I thought I would be nice to have all these "personal" functions collected in one place, and to make them available in R no matter which

(Before starting: I'm a total R noob so please bear with me in case of any error or faux pas). Hi, For a small project, I'm writing a few simple R functions and calling them from python (using RPy). I'm sharing the code with a couple of friends, using a subversion server. Now, I want something like a package, to be able to share functions between ourselves. Having read a few package

Hello, I have a dataframe containing various time series (not time series objects though!)with hourly time steps. I?d like to perform ccf for I need to know the correlation factors for different lags. Here is an example: x<-as.POSIXct(c("2008-12-25 16:00:00", "2008-12-25 17:00:00", "2008-12-25 18:00:00", "2008-12-25 19:00:00", "2008-12-25

Dear all, I would like to produce a map with information about the patenting activity in German districts, by coloring districts with different degrees of patenting activity in different colors. I work with the packages maptools, maps and spdep. The map data is read from an external .shp file (+ the corresponding .shx and .dbf files). Plotting a map with the IDs or the patenting indicator itself

Hi there, I'm a bit confused concerning the axis tck setting in the lattice package as the ticks on left sided axis aren't drawn at all with the following setting: dados <- data.frame(varsep = factor(rep(1:2,10)), i = runif(20)) library(lattice) my.theme <- list( axis.components = list(left = list(tck = 1, pad1 = 1, pad2 = 2), top = list(tck = 0, pad1

Hi, I've got the following problem which I cannot think of a solution right now: if got a lattice xyplot in black and white and a grouping variable with many (more than 8 values) and I plot it as regression lines (type="r"), just like this one (not reproducable but that's I guess not the point here): xyplot(log(AGWB) ~ log(BM_roots), data=sub_agwb_data, groups=species,

Hello, I have a dataframe assigning various scores on around 20 variables to a list of countries. The scores are rated on a scale of (D, C, B, A) and there are also some not rated ones (NR) and others are left blank (NA). I now wanted to transfer the scores into numeric values (such as NR=0, D=25, C=50, B=27, A=100), while also leaving the NA in the dataframe. Can I transform the whole

Hi, there´s something that really bothers me about R and after hours and hours of internet research, I´m still stuck with the same problem: I installed R and it is in Spanish, as the system on my work. I would really like it in English and there seems to be no way to change that!?! I´m doing an abroad internship, so my Spanish is far from perfect and my tutorial is in English. Is there any

Hi, how do I create a string of the comma-separated content of a vector? I've got the vector i with several numeric values as content: >str(i) num 99 and want to create a SQL statement to look like the following where the part '(2, 4, 6, 7)' should be the content of the vector i: select * from [biomass_data$] where site_no in (2, 4, 6, 7) Here my approach (which doesn't

Hi there, I've got a question which is really trivial for sure but still I have to ask as I'm not making any progress solving it by myself (please be patient with an undergraduate student): I've got a linear model (lm and lmer fitted with method="ML"). Now I want to compare the coefficients (slope, intercept, not the random effects) of both models with a given value (e.g.

Hello, I'm trying to use na.spline (package zoo) to fill some missing data in a time series. this works fine, however, if I apply the 'maxgap' argument, I always get the error: <------ Error in na.spline.vec(x., coredata(object.), xout = xout., ...) : attempt to apply non-function ------> I couldn't find a similar error for this case in the mailing lists and zoo vignette,

Hi everybody, I started to receive a weird message in R that I have never seen before...also I haven't found anything on google or on this forum about it.

Hi everyone, is it possible to write a certain value beside a point in a plot? I'm plotting the following: plot(coefficient$intercept ~ coefficient$average_BM_leaves_needles, main="intercepts ::: BM_leaves_needles", ylab="intercepts", xlab="average BM_leaves_needles per site [kg]") and I want to have the value of coefficient$site_no written beside each
