Hm, I am not an expert in this field but trying to use obviously old package which was removed about 5 years ago from CRAN is asking for problems. There is probably some incompatibility between recent R version and obsolete package. You either 1. need to install/compile R version from 2012 and install/compile this old package for this version. 2. Or you could try to find some similar

Hi, I?m new to R but I?m interested in using the fdim package to find the fractal dimension of a dataset. I downloaded the the package from https://cran.r-project.org/src/contrib/Archive/fdim/ and successfully installed it together with xgobi. However, when I try to run the first example, after df <- fdim(mydata,q=0,Alpha=0.3) I get the following error: Error in .C("pointdif",

Hi, I'm a bit puzzled. I uses exactly the same code in RcppExamples package to try adding RcppFrame object to RcppResultSet. When running it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat 64bit. I'm not sure if this is the cause of the problem. Any advice would be greatly appreciated. Thank you. Rob. int numCol=4; std::vector<std::string>

Hi, I had the following code: testp <- rcorr(t(datcm1),type = "pearson") mat1 <- testp[[1]][,] > 0.6 mat2 <- testp[[3]][,] < 0.05 mat3 <- mat1 + mat2 The resulting mat3 (smaller version) matrix looks like: NA 0 0 0 0 NA 0 NA 0 0 NA 2 0 0 2 NA To get to the number of times a '2' appears in the rows, I was

Dear List, somebody knows, if the following operation can be done in an easier way? The data rows which should be read into R look like that: 4547;1970.01.01 00:00-1970.01.01 01:00; noData Unitil now we are doing this procedure: 1. Dividing columns which are separated by ";" => temp <- read.table(file ,sep=';', na.strings='noData', strip.white=TRUE) =>

Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think. I have very big data but I have created a hypothetical data for simplification. for example I have : table 1 table 1: species occurance data

I wrote something to check for duplicate rows in a data frame, but it is too inefficient. Is there a way to do this without the nested loops? This code correctly indicates rows 1-7, 1-8, 2-9 and 7-8 are duplicates. > m <- matrix(c(1,1,1,1,1, 2,2,2,2,2, 6,6,6,6,6, 3,3,3,3,3, 4,4,4,4,4, 5,5,5,5,5, 1,1,1,1,1, 1,1,1,1,1, 2,2,2,2,2, 7,7,7,7,7), ncol=5, byrow=TRUE) > df <- data.frame(m)

The menu directory won't compile with gcc 3.4.0 because gcc complains that "ebp" cannot be used as a constraint. If preserving ebp is necessary then it will have to be done in the assembler code. Gcc 3.3.3 just seems to ignore the constraint. It didn't do anything special to preserve the register. I also noticed that getnumrows returns the contents of 0x484 which is the

Hello, I discovered SAGA, an interesting free GIS, a few days ago and now, I would like to use it from within R 2.6.2 using the RSAGA package. I read the documentation for this package and thought that I understood it correctly for trying to call some of the SAGA modules. For getting the information on the usage of and arguments required by the SAGA command line "Import Binary Raw

If I want to do a join based on *two* matching fields in two data frames, can merge() handle this? It appears to only handle a single matching column -- do I need to make a "metacolumn" or is there some way to do this? E.g.: Dataframe 1 contains columns A,B,C and Dataframe 2 contains A,B,D I want an output A,B,C,D which places C and D together if A and B match (otherwise, make two

Howdy Folks, I am running R version 2.7.2 (2008-08-25) on CentOS 5.2 - the standard RPM distribution. I am having a curious occurance trying to run a R script from within a shell script. Basically, I have a small R script that processes a file. It takes two parameters - the input file, and the output file. I then have a shell script that runs the R script for each file matching a glob. R

Hello, I'm working with R version 1.5.0 in Windows. I've written a function (SummaryMat, segment below) which uses a loop to repeatedly call another function (PercentsMat, segment below). PercentsMat creates a matrix and adds rows to it each time it is called. I use deparse(substitute(...)) to get the names of the lists sent to PercentsMat to use them as row names in the generated

Hi All- I have created a subset of my original csv for the times I am interested in (9, 12, 3). I have a subset for all of those times then each individually. I would like to have specific case studies to analyze individually for those times. For example, I want to look at 2009/06/01-2009/06/10. Is the easiest way to created a subset of ss? I haven't been able to figure out the easiest way

Dear All, I have the following code which works fine but takes 16+ hours to run and I was hoping someone could give me a hint as to how I could make it more efficient. Let me explain what the code is supposed to do. Each single row of the m.o.f matrix (n*p dim) has to go through the following operation Dm*m.o.f[i]^alpha1m where both Dm and alpha1m have n*1 dimensions. Each row of the m.o.f

Hello, it seems to be a simple problem, but I couldn't find an answer in the archiv. (I think, it must has something to do with the group-select, like in php) I've the following data.frame: A B C 1 3 6 5 2 4 4 20 3 5 8 2 I want to get the number of the

Is there a way to generate a new dataframe that produces x lines based on the contents of a column? for example: I would like to generate a new dataframe with 70 lines of data[1, 1:3], 67 lines of data[2, 1:3], 75lines of data[3,1:3] and so on up to numrow = sum(count). > data pop fam yesorno count 1 126 1 70 1 127 1 67 1 128 1 75 1 126 0 20 1 127

I am using the library(bigmemory) to handle large datasets, say 1 GB, and facing following problems.
