Hello, I was wondering if anyone knew how to fit a series using a Garch-M (Garch in the mean) model. From what I gathered from the documentation, it does not seem to be implemented in either fGarch, fSeries, or tSeries. Perhaps there is an option that allows this functionality. Otherwise, if it's possible to modify an existing function I would appreciate any guidance on how to go about

Hi, I am fairly new to GAM and started using package mgcv. I like the fact that optimal smoothing is automatically used (i.e. df are not determined a priori but calculated by the gam procedure). But the mgcv manual warns that p-level for the smooth can be underestimated when df are estimated by the model. Most of the time my p-levels are so small that even doubling them would not result

Hi, Without trying to print 1000000 points (see <http:// finzi.psych.upenn.edu/R/Rhelp02a/archive/42105.html>), I often print maps for which I do not want to loose too much of coastline detail, and/or plots with 1000-5000 points (yes, some are on top of each other, but using transparency (i.e. rgb colors with alpha information) this actually comes through as useful information.

Hi, I'm wondering why 48 %/% 2 gives 24 but 4.8 %/% 0.2 gives 23... I'm not trying to round up here, but to find out how many times something fits into something else, and the answer should have been the same for both examples, no? On a different topic, I like the behavior of NAs better in R than in SAS (at least they are not considered the smallest value for a variable), but at the

Hi, I don't understand the following. When I create a small artificial set of date information in class POSIXct, I can calculate the mean and the median: a = as.POSIXct(Sys.time()) a = a + 60*0:10; a [1] "2009-03-10 11:30:16 EDT" "2009-03-10 11:31:16 EDT" "2009-03-10 11:32:16 EDT" [4] "2009-03-10 11:33:16 EDT" "2009-03-10 11:34:16

Hi, As part of the legend to a plot, I need to have the "n" in italics because it is a requirement of the journal I aim to publish in: "This study, n = 3293" Presently I have: legend(20, 105, "This study, n = 3293", pch=1, col=rgb(0,0,0,0.5), pt.cex=0.3, cex=0.8, bty="n") I suppose I could leave a blank in place of the "n",

Hi, Sometimes data series (not necessarily time series) suffer breaks where data were expected, but not collected. Often the regular "lines" command to add such data to a plot is what I want, but other times I'd like the line to break where the data series is interrupted, instead of the line jumping to the next point in the series uninterrupted. Usually my data file

Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title. I have a math expression that raises the height of my title. If you don't mind the non-sensical title I give to the legend for this plot (Figure 3.20 in R Graphics): with(iris,

Hi, I have data on stomach contents. Possible prey species are in the hundreds, so a list of prey codes has been in used in many labs doing this kind of work. When comes time to do analyses on these data one often wants to regroup prey in broader categories, especially for rare prey. In SAS you can nest a large number of "if-else", or do this more cleanly with "select"

Dear list members, I have to combine dataframes together. However they contain different numbers of variables. It is possible that all the variables in the dataframe with fewer variables are contained in the dataframe with more variables, though it is not always the case. There are key variables identifying observations. These could be used in a merge statement, although this won't

Hi, I have used package quantreg to estimate a non-linear fit to the lowest part of my data points. It works great, by the way. But I'd like to extract the predicted values. The help for predict.qss1 indicates this: predict.qss1(object, newdata, ...) and states that newdata is a data frame describing the observations at which prediction is to be made. I used the same technique I used

Dear list, I've tried to search the archives but found nothing, although I may use the wrong wording in my searches. I've also double-checked the upData function in Hmisc, but it does something else. I'm wondering if one can update a dataframe by "forcing into" it a shorter dataframe containing the corrections, like the "update" provided in SAS data steps.

Hi, I'm trying to move to R the last few data handling routines I was performing in SAS. I'm working on stomach content data. In the simplified example I provide below, there are variables describing the origin of each prey item (nbpc is a ship number, each ship may have been used on different trips, each trip has stations, and individual fish (tagno) can be caught at each

Hello R users, I have to import a file with one column containing dates written in French short format, such as: 7-d?c-07 11-d?c-07 14-d?c-07 18-d?c-07 21-d?c-07 24-d?c-07 26-d?c-07 28-d?c-07 31-d?c-07 2-janv-08 4-janv-08 7-janv-08 9-janv-08 11-janv-08 14-janv-08 16-janv-08 18-janv-08 There are other columns for other (numeric) variables in the

Hi, I have read about the use of symbols() to draw circles of different sizes, but I have not been able to find out how to add a legend to such a graph, legend that would display some specific sizes and their meaning. Before finding the symbols function in Paul Murrell's book, I had rolled by own function where the variable I want to use to control circle size was actually used to

Hi, Being in the process of translating some of my SAS programs to R, I encountered one difficulty. I have a solution, but it is not elegant (and not pleasant to implement). I have a large dataset with many variables needed to identify the origin of a sample, many to describe sample characteristics, others to describe site characteristics. I want only a (shorter) list of sites and their

Hi, I'd like to compute the weighted mean of some variables, all using the same weight variable, for each combination of 3 factor variables. I found how I could use "summarize" (from Hmisc) to do normal means for combinations of 3 factors, but I cannot find a way of doing weighted means. Is it possible in R? Thanks in advance, Denis Chabot

Hi, This is probably documented, but I cannot find the right words or expression for a search. My attempts failed. I have a data frame of 3 vectors (x, y and z) and would like to transform this so that I could use persp. Presently I have y-level copies of each x level, and a z value for each x-y pair. I need 2 columns giving the possible levels of x and y, and then a transformation of

Hi, Is there a way, preferably with R, to read shapefiles and transform them in a format that I could then use with package PBSmapping? I have been able to read such files into R with maptools' read.shape and plot it with plot.Map, but I'd like to bring the data to PBSmapping and plot from there. I also looked at the package shapefile, but it does not seem to do what I want
