Dear friends, I am having some doubts about the amount of memory that is being used by R in my Mac (MacBook Pro, 2Gig). Is there a way to increase the amount of memory used? When I type: > mem.limits() the result is: nsize vsize NA NA and I can't change it, tough my computing in R isn't using all the memory at it's disposal. Best regards, Carlos -- Carlos GUERRA

Folks: In the past 2 days I have seen a large increase of spam getting into R-help. Are others experiencing this problem? If so, has there been some change to the spam filters on the R-servers? If not, is the problem on my end? Feel free to reply privately. Thanks. Bert Gunter Genentech Nonclinical Statistics South San Francisco, CA 94404 650-467-7374

I have two data matrices that I want to make the correlation between each column from data1 and each column from data 2 and also calculate the p-value Matrices dont have the same size and I tried such a script. > bg <- read.table (file.choose(), header=T, row.names) > bg > Otu00022 Otu00029 Otu00039 Otu00042 Otu00101 Otu00105 Otu00125 Otu00131 Otu00137 Otu00155 Otu00158 Otu00172

Dear friends, I am beginning to use R software in my academic research and I'm having some problems regarding the use of PCA. I have a table with 24445 rows and 9 columns, and I used the function prcomp() to do the analysis. Working with an example?: x<-read.table("test.txt", header=T) row.names(x)<-x[,1] x<-x[,-1] require(stats) pca<-prcomp(x, scale=T) names(pca) ##

Hello All, I have a data frame (dput information below) with food item weight for fish species. I need to calculate the Mean proportion by weight of each food item for each specie, as show in solution data frame (dput information below). I use the ddply function (plyr package) in two steps. First calculate the proportion of weight for each individual: step1 = ddply (example, .(ID), transform,

Hi everyone. I have a question about a work on R I have to do for my job. I have temperature data coming from 70 weather stations. One data file corresponds to one station for one year (so 70 files for one year). Each file looks like this (important: each file contains NAs): time data 01/01/2008 00:00 -0.25 01/01/2008 00:15 -0.18 01/01/2008 00:30 -0.25 01/01/2008

Hello, I have a question about error handling. I run simulation studies and often the program stops with an error, for example during maximum likelihood. I would like the program not to stop but to continue and I would like to ask how the error handling can be set up for this (if it can). I tried to look through manuals etc but unfortunately did not get closer to the solution. Below is a

Hello everyone, I am working for a few days already on a basic algorithm, very common in applied agronomy, that aims to determine the degree-days necessary for a given individual to reach a given growth stade. The algorithm (and context) is explained here: http://www.oardc.ohio-state.edu/gdd/glossary.htm , and so I implemented my function in R as follows: DD <- function(Tmin, Tmax, Tseuil,

new R user has a question: I have several hundreds of .txt files from different monitoring sites over several years. (1) different site has a unique name( such as : ST2.20090321.txt = Sation 2 2009 March 21 data, ST3.20090322=Station3, 2009, March 22 data). (2) different site has different file header, but for the same site, the header is the same. for example: Sation 2 date time wind CO2

Dear R and odfWeave users, I am looking for a way to automate generation of many reports using odfWeave. All reports would use the same input ODT file, the only difference would be in the name of the dataset which will be analyzed in any particular report. Right now, the name of the dataset is hardcoded in the first code chuck in the input file: <<01 get data, echo=TRUE>> station =

Dear list members, I am working with a multilevel growth curve, that in its simplest form goes like follows: Yit = Ai + Bi t + eit (the error term is assumed to follow an AR(1) autorregressive process) One major topic in my research is the convergence in the values of Y over time. Thus, I am interested in the relationship between the random effects for the intercept and the slope, and I

Hello, I am maintaining different resources related to Ogg Theora, both as a user and as a contributor to several local advocacy groups. I had a couple of questions: - Who should I ask / talk to about financing improvements to the Cortado applet (namely: bigger / more visible controls for the seek functions) ? - Are there any simple Ogg Theora editing tools or applications, similar to avidemux

I am a new R user but a long time SAS user. I searched for a response to this question but no luck, so forgive me if this topic has been covered before. I am running a TukeyHSD post hoc test after running an ANOVA. I get the results of all pairwise comparisons, no problem. However, the output table is a little "busy", and I'd like to make the output easier to read. Specifically, I
