similar to: idea for (further) debugging ace ()?

Dear all, well, today I just seem to run into these problems ... (I am still working on R 0.63.1 on a SuSE 5.2). I would like to have a data.frame that also contains character (and NOT factor) vectors. Two things that I tried (the second worked in R 0.62.2): > test.df <- data.frame (X= character (4)) > test.df$X [1] <- "a" Warning: invalid factor level, NAs generated or:

Dear all, Many thanks to all who always so quickly respond with helpful hints! Currently I am working with R 0.63.1 on SuSE 5.2 which I installed this morning within about half an hour: my deepest compliments to the developpers! (I had still 0.62.2 before.) This time I am trying the following: > xy <- list (a= c (1, 2, NA), b= c (2, 3)) > list.name <- "xy" > get

Dear all, I think this question has been raised very recently but I think I didn't see repsonses on the list nor did I find the thread in the archives. (If it is there I'd appreciate directions ...) I am about to install Linux on a Compaq notebook. One important thing I want to do is being able to run R. I have fiddled with different distributions of Linux (LST, SuSE, Debian) and can

Dear all, I would like to fit an lm in which a subset of the explanatory variables are linearly dependent. Thus I would like to include the restriction that all betas of these variables sum to 1. Is there a way to this in R? Or is this what happens automatically if I set singular.ok= T (which is the default, I believe)? Thanks for your help. Lorenz --

Dear all, The following works with a simple result of lm but gives the error with a more complicated one (could this be due to singularities that occurr in the model?). > cooks.distance (X) Error: NAs in foreign function call (arg 6) > class (X) [1] "lm" But, actually, I would like to ask a more general question: Is there a place (I searched in the CRAN site) where I find

Dear all, is this a bug or do a miss something (this concerns version 0.63.1 on Linux)? > boxplot (c (1, 2, 3, 4, 5), ylim= c (-5, 5)) Warning: parameter "ylim" couldn't be set in high-level plot() function > boxplot (c (1, 2, 3, 4, 5), pars= list (ylim= c (-5, 5))) Warning: parameter "ylim" couldn't be set in high-level plot() function > and actually in

Dear all, in a current project I have a pretty huge .Rdata. Thus I was working with R --vsize 100 --nsize 1000000. Today when I tried to restart R I get the following error message: Error: a read error occured Fatal error: unable to restore saved data (remove .RData or increase memory) I increased memory up to --vsize 180 and --nsize 2000000, but the error reoccurrs. Is there a way to know

Dear all, I am working with R Version 0.62.2 (July 10, 1998) on a SuSE Linux 5.2. I have troubles in understanding the function image (). Can someone enlighten me? I'd like to draw a square image-plot (with every little part of the image a square as well) and add some (straight) lines to it. Also, I create an empty z matrix which I need to fill step by step. Thus I tried to find out how

Dear all, I am still trying to find out what goes wrong when I use ace (I get an 'NAs in foreign fuction call (arg3)' but when I go through it with debug there seem no data to be missing). I had some errors (see at end of message) while installing 'acepack'. Do you think it is possible that these lead to the fact, that simple problems run ok but larger problems result in an

Dear all, I would like to use the biological symbols for male and female as plotting symbols in a scatterplot (ideally filled and non-filled). R does not seem to have these symbols using pch= in plot() nor are they implemented via expression() or at least I did not find them. I found that the symbols are e.g. available in the wasysym and the marvosym package in LaTeX. I have coded two very rough

Dear R users, Is there something like predict (..., type= 'response') for glmmPQL objects or how would I get fitted values on the scale of the response variable for the binomial and the poisson family?

Dear R-mixed-effects-modelers, I could not answer this questions with the book by Pinheiro & Bates and did not find anything appropriate in the archives, either ... We are preparing a short lecture on degrees of freedom and would like to show lme's as an example as we often need to work with these. I have a problem in understanding how many dfs are needed if random terms are used for

Dear R users, I have not found anything on this in the archives. Does anyone know whehther the parameter use= is not functioning in cor or enlighten me what it is supposed to do? My R version is "R version 1.8.1, 2003-11-21" on Windows 2000. I am hoping to be able to update to 1.9.1 as soon as it has appeared (we are not allowed here to install software on our own and thus I am trying

Dear all, I am doing some data handling and tabualtions and then I am using glmmPQL to fit a binomial hierarchical model (which I assign to a new object). If I do a save.image () or a q ('yes') after this, I get the following warning messages: Warning messages: 1: namespaces may not be available when loading 2: names in persistent strings are currently ignored Sometimes R seems to

Hello R-user! I am running R 2.7.0 on a Power Book (Tiger). (I am still R and statistics beginner) I try to find the most important variables to divide my dataset as given in a categorical variable using randomForest. Is randomForest() able to deal with count data? Or is there no difference because only the ranks are used in the trees? Thanks in advance Birgit Birgit Lemcke Institut f?r

Hello R-user! I am running R 2.7.0 on a Power Book (Tiger).
