similar to: What is RDA file and how to open it in R program?

Hi, Does anyone know how to export .RDA file (in R program) to a normal text file (readable by any text editor)? Also, how to export an object in R program into a text file (not .RDA file)? Thank you. Jittima

Hi, I want to change .RDA file to a text file. So I did as follows. >load("my.rda") >ls() ---> then it showed [1] exprs >write.table(exprs,"C:\\my.txt",sep="\t") I was successful with the first .RDA file. Then I used the same commands with another .RDA file (172 MB)which is 4 times bigger than the first file (41.2 MB). When I put the last command

Hello I try to fit a LDA and RDA model to the same data, which has two classes. The problem now is that the training errors of the LDA model and the training error of the RDA model with alpha=0 are not the same. In my understanding this should be the case. Am I wrong? Can someone explain what the reason for this difference could be? Here my code: LDA model: =========== % x is a dataframe tmp =

Dear developeRs, my package FrF2.catlg128 holds large catalogues and is supposed to gain additional ones. All the catalogues are intended for the user. So far, the catalogues were stored in the data directory, and LazyData was "no". I understand that this is not considered wise any more (if it ever was), so that I want to change to LazyData "yes" with the next release

I've tried a few things both with prcomp(), and rda() and its friends in vegan (including biplot.rda and ordiplot), but can't find a solution. I'd like to associate subsets of the points in a resulting biplot ("sites" in the rda object) with different plotting colors/text styles to emphasize certain sets of points. I can't figure out how to keep the arrows (for

Dear all, I'm performing RDA on plant presence/absence data, constrained by geographical locations. I'd like to constrain the RDA by the "extended matrix of geographical coordinates" -ie the matrix of geographical coordinates completed by adding all terms of a cubic trend surface regression- . This is the command I use (package vegan): >rda(Helling ~

Dear all, I did a RDA and when I looked to the signification of the test with permutest, the output was non-significant. But when I used the envfit function, some of the vectors are significant. All the test's conditions are respected. What it means? Is it an error in the script? Commands and output: > permutest(rda.ind, perm=999, first=TRUE) Permutation test for rda  Call:

Dear users, I would like to process all the lists from all *.rda files that I have in one folder. Up to now, I can load all the *.rda files without any problem. The problem is when I want to access the list saved within each *.rda file (only one list per rda file). Here is my code: fpath <- "D:/R" listnames <- list.files(path=fpath, pattern=glob2rx("*.rda"),

Hi Im using the VEGAN package to do an RDA ordination. In my plot I get my environmental scores as arrows/vectors, but my species scores as points. I would like to get the species scores as arrows as well. I tried the envfit function, and this creates arrows, but the lenght is not proportionate to the strengh of the correlation and the point is still there (so I both have point and arrow). fit

I'm trying to perform a RDA analysis in the vegan package using the "varpart" function. I have a matrix of community structure data in different sites (rows), which I want to explain using 3 matrices of environmental data. The 3 matrices are: water quality parameters; local land use variables; total land use variables. In each matrix, the number of the rows is the same (the

Hi, to speed up computations in our RobASt family of packages, we use interpolation on a grid of precomputed values which we save together with the interpolating functions (results of splinefun essentially) in sysdata.rda in the R folder of our pkg. After adding grids for some more models, this file has grown considerably, even after application of tools::resaveRdaFiles. At the moment we are at

I am not familiar with the vegan package, so I am just making a guess here. If 'na.action=na.omit' is part of the call to varpart, try removing it from the function call and moving it above as follows: options(na.action="na.omit") RDA_Ger <- varpart(comm, x1, x2, x3, transfo="hellinger", scale = FALSE) Maybe that will help.

Hello, I used the lda function from the MASS (VR) package and the rda function from the klaR package. I wanted to compare the result of this two functions by using the same training set. Thus, I used the rda function with lambda=1 an gamma=0, I should emulate the lda function and I should obtain the same result. But this it not the case, the two result are very different. My training set is

Hi, I have seen the answer to this sometime before but I just can't find it again - pointers appreciated. I have a package that contains some data.frames saved as .Rda files in the data/ directory. When the package is loaded I would like to have them be available in the workspace (without the user having to explicitly load them using data(...)). If my package does not use a NAMESPACE, I can

Dear all, I am trying to do a n-fold cross-validation for a regularized discrimant function analysis using rda from the package klaR. However, I have problems to predict the groups from the test/validation sample. The exmaples of the R documantation and some online webpage also do not work. Does anybody know what I have done wrong? Here my code # I want to use the first 6 observations for

Dear everybody: We used the fine foreign library to bring in an SPSS dataset that was about 9 megabytes and I can squeeze it into a much smaller R object using compression with save(ndat, file="NatAnnES2000.rda", compress=T). I can use load() to get the "ndat" dataframe back, that's all good as far as I can see. If I put that file in the data subdirectory, then the

Hello I'm triying to import data to R What is the problem? > es_rda <- read.table("D:\\fdrtrees\\data\\es.rda",sep=",",header=T) Warning message: incomplete final line found by readTableHeader on 'D:\fdrtrees\data\es.rda' Thank you a lot Rita [[alternative HTML version deleted]]

Hi, I am getting a strange error with 15.0 which I've not seen with previous versions of R.
