similar to: thin plate splines

Hello, I'm a student at the University of Klagenfurt / Austria and I need some help ! I have to predict 24 daily load-values. Therefor I got a dataset with following colums: 24 past daily load-values 6 past daily temperature-values My goal is to find a model (GAM with thin plate splines) in R. I found the function "gam" in the R-library "mgcv", but it just fits

Hi I'm using the gss package to fit thin plate splines. I've fitted the tps without problems and got a ssanova object. Then I wanted to do some prediction using a new set of data (latlon data) and I got an error message: > predict.ssanova(recs.spliney,recn.grid,se.fit=FALSE) Error in array(x, c(length(x), 1), if (!is.null(names(x))) list(names(x), : attempt to set an

Hi I'm working on a remote computer with R (SuSE 8.1) and I want to do some ploting. Does anyone knows if it is possible to export the graphics window in to my display and how I can do it ?

Hi Everyone, I'm a pretty useless r-er but have data that SPSS etc doesn't like. I've managed to do GLMs for my data, but now need to fit a thin plate spline for my data (arcsine.success~date.num:clutch.size) If anyone has a bit of spare time and could come up with a bit of code I'd be very grateful- I just don't get R language!

Hi I'm doing a bootstrap of a linear model using: boot.fishpower <- function(data, i){ data <- data[i,] fplm <- lm(log(U)~Q+S+P+B+D, data=data) fp <- coef(fplm) exp(fp) } > boot(logglm.data,boot.fishpower,100) Error in "[<-"(*tmp*, r, , value = statistic(data, i[r, ], ...)) : number of items to replace is not a multiple of replacement length

Hi I have a list with several data.frames, all with the same number of colunms but different number of rows, and I'd like to transform this list into a single dataframe. I need to mimic an rbind of all dataframes ...

Hi Maybe this is not an issue about R. It's probably a programming issue and I am not a developer at all. Anyway my main developing activities are in R and that's where I have difficulties. When I develop a function or group of functions I lose eternities with the objects attributes and classes. I do a lot of object manipulation (lists to arrays, factors to numeric vectors, etc, etc) so

Hi! I 've a problem to have a lognorm distribution with mean=1 and var (or sigma)=1. rlnorm(1000,0,0) rlnorm(1000,1,1) rlnorm(1000,0,1) .... ? Can you help me?

Hi I have a matrix (4 x 950) and I want to remove 3 rows, where the values from the first column are 713, 714 and 715. I can select the rows, one by one, with mat[mat$first==713,] mat[mat$first==714,] ... but I'm unable to (i) select the 3 rows at once, (ii) select the matrix excluding those rows. How can I do it ? Thanks EJ

Hi I would like to know if the "penalty associated with the fit" that is printed by the summary.ssanova function is the smoothing parameter (\lambda) of the criterion function that's minimized to find f.

Hi I've imported some data from a oracle database and the strings have a lot of blank space (because of the delimiter). I want to remove these blanks space with something similar to a trim function. I don't find a trim function or something similar. Can someone give a help on this ? Thanks EJ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hi I've just submitted to the NEdit development team a R highligth patterns for NEdit (www.nedit.org). NEdit is a text editor for LINUX which I use to write small R functions. In my opinion is a very good tool for small scripts, maybe for huge projects is not the best. I'm attaching the R-5.1.pats file so you can try it. As usual contributions and comments are welcome.

Hi I wrote a function implementing an algoritm for simulation of spatial sampling plans (using geoR). I'm using a range of parameters to perform several simulation and sometimes this parameters create function errors wich cause the algoritm to stop. How can I avoid this ? Below there's a small example that I made to study the problem but I was not able to solve it. I've tried

Hi, dear list members, I've been using R under windows XP and I am now changing my system to SUSE LINUX 9.3. I could figure out that there is no precompiled version of R for LINUX. To get me going, I would like your help regarding what I need to setup R under my SUSE LINUX. Which compiler do I need to be able to compile the source and I was wondering if I could get GNU compiler?

Hi I want to use save methods but I found that the save function is not a generic function ... If I define save <- function(x, ...) UseMethod("save") I'll be overwriting the original save function ... Is there another way of doing this ? or am I understanding it wrong ?
