Hi R lovers! Are there any means to define and plot a function given the equation that specifies the function? For example I'd like to plot and work with the Gumbel Distribution density defined by Lambda(x)=exp(-exp(-x)) My question may appear very simple but I haven't got an idea yet about how to do that. I could plot something with x a vector/set of value but I don't know how to

hi, rgev function gives me random deviates and I have a data set which I am fitting to an EVD,IS there a way I can plot both observed and ideal evd on the same plot thankyou Rangesh

Hello, and please advise regarding any errors/omissions on my part. However, the documentation for R's tcplot function in the evd package appears to contain an error. I am using evd version 2.2-4 in R 2.14.0 with Windows XP. > data(portpirie) > mrlplot(portpirie) ## No Error > tlim <- c(3.6, 4.2) > tcplot(portpirie, tlim) ## Line from documentation Error in fpot(data, u[1],

Hi, I am using the clusters function in the evd package and was wondering if anyone knew how to set the row names as date/time objects. My data has 1 column of date and time and another of wave height (H). My two options are: 1 - When in import the data using read.table make sure that the row.names is set = 1 giving row names to the H data. 2 - Import H from the data file and set the row names

Dear List I hope you can help me: I?ve got a dataframe (df) within which I am looking for Peak Over Threshold values as well as the length of the events. An event starts when walevel equals 5.8 and it should end when walevel equals the lower threshold value (5.35). I tried ?clusters (?)? from ?evd package?, and varied r (see example) but it did not work for all events (again

As I tried to draw random sample from Hüsler-Reiss density with the following code, library(evd) margins <- cbind(0, 1, seq(-0.5,0.5,0.1)) x <- rbvevd(101, dep = 1.7, model = "hr", mar1 = margins) [,1] [,2] [1,] -0.56662298 0.8448505 [2,] 0.55824918 1.0217279 [3,] 0.24741124 0.6684668 [4,] -0.31547985 0.1781680 [5,] 0.69466134 0.2299363 [6,]

Hi, I use the function fpot of packages evd. If I call the fit that I obtain "fit", I want to modify the name of the axis and the main title that is produced by plot(fit1). To do this, I want to create a new function where I would have the names modified. The problem is that I can't find the function that produce these plots... I tried to see in plot.uvevd but it doesn't seems

hello everybody i want to use the maximum likelihood method to estimate FRECHET parameters of my sample data. Should it work with fitdistr in the package MASS? I only find how to do it for GEV, Gumbel, and almost all other distributions, but FRECHET? I would be very happy if somebody can tell me how to do fit the FRECHET distribution! Thanks Nadja Riedwyl

Hi, I am trying the following: library(ismev) library(evd) fit <- gev.fit(x,show=FALSE) ks.test(x,pgev,fit$mle[1],fit$mle[2],fit$mle[3]) but I am getting: Warning message: cannot compute correct p-values with ties in: ks.test(x, pgev, fit$mle[1], fit$mle[2], fit$mle[3]) where x is: [1] 239 38 1 43 22 1 5 9 15 6 1 9 156 25 3 100 6 [18] 5 100

I want to use the plot(model) function to generate Tukey-anscomb and Q-Q plots of a lm(). I manage to change all labels but the main one which apparently is neither main or sub. So far I have tried as par setting: cex (changes symbol size within the plot), cex.main (no effect), cex.sub (no effect) cex.lab (changes label size), cex.axis (changes axis label size). What I would like to change is the

Hello everybody 1. If there is/ever will be a function to perform "duncan multiple range test" please inform me at once. 2. Is there a way to create a grouping as duncan does from TukeyHSD output? My experimental design contained 62 genotypes, so the pairwise comparison is not that usefull and clear to look at. How would I do that? Is there an other test that does give grouping as

Dear R helpers I have some data and through some other software, it is understood that I can fit the Frechet Distribution to it. However, I need to fit the distribution using R code only. I have searched many R packages and one R helper has suggested some sites too, but unfortunately parameters couldn't be estimated. Using LMOM package, I know how to estimate the parameters of Generalized
