I am curious whether anybody has or is developing this capability within R. I have not found any software yet that has this capability and I am not sure whether it is too new a method and nobody is actually using it, or if there are other means to get the same analysis that I do not know of. Any information regarding developments or use of this method would be helpful. Melanie Edwards

i'm in the midst of using R for a PVA/matrix project. my math skills are lousy and programming skills are worse. to deal with an error that i couldn't solve, i changed a parameter that used a new part of a routine in our PVA package's code: else if (ES == "ParDraw") { require(MASS) (previously, ES was "MatrixDraw" and MASS wasn't called for) now,

Hello, I'm in need of running a PVA and want to load {popbio}. However, I can't find it. I can't see where or how to load it. I have added repositories and changed the CRAN mirror site. I see {polynom} and {popgen} but no {popbio} between. What am I doing wrong? Thanks, Michelle [[alternative HTML version deleted]]

Hi all, I'm new to PCA in R, so this might be a basical thing, but I cannot find anything on the net about it. I need to make a PCA plot with two response variables (df$resp1 and df$resp2) against eight metabolites (df$met1, df$met2, ...) and I don't have a clue how to do... and I've only used the simplest PCAs before, like this: pcaObj=prcomp(t(df[idx, c(40:47)]))

Hi, there: I am wondering if anyone here can provide an example using pca doing dimension reduction for a dataset. The dataset can be n*q (n>=q or n<=q). As to dimension reduction, are there other implementations for like ICA, Isomap, Locally Linear Embedding... Thanks, weiwei -- Weiwei Shi, Ph.D "Did you always know?" "No, I did not.

Hello, I am trying to create multiple matrices (to run a PVA) but can't import all of them from a .csv without the numbers treated as labels and not factors. I can enter the matrix slowly: Site05_96 <- matrix(c(0.07,0,0.03,0.00,NA,0.00, 0.09,0.166666667,0.31,0.42,NA,0.00, 0.00,0,0.00,0.00,NA,0.00, 0.00,0,0.00,0.00,NA,0.00,

Hello, When used in SILK mode, is there a way to manually modify the pitch (F0) of the speech signal before resynthesizing during Opus decoding? In the below, we have modified the pitch lags of (4), e.g., with a constant scaling factor 0.5 to decrease the pitch of the voice by one octave. However, the result was perceptually the same as without modifying the pitch lags. +---------+

Dear R-ians, I want to perform an linear unmixing of image pixels in fractions of pure endmembers. Therefore I need to perform a constrained linear least-squares problem that looks like : min || Cx - d || ? where sum(x) = 1. I have a 3x3 matrix C, containing the values for endmembers and I have a 3x1 column vector d (for every pixel in the image). In theory my x values should all be in the

I would really appreciate it if anyone could determine what is going on with the following command. It is only half-working and is losing lots of data. For the life of me I cannot even see the pattern of what it is losing and what it is not. I am attaching the R data set which you can use with the Load Workspace menu function.

So it seems we've found the problem - just in case someone else encounters it. We had previously joined the Server with net ads join, and the attributes were still present in active directory, and the vista client tryed to force a kerberos blob on the samba server - which was promptly ignored/rejected. The solution was deleting the AD entry for the server and re-joining. Mit

A colleague suggested that some R software was available for estimating "Independent Components Analysis" (ICA) (... signal separation). If so, I''d appreciate any pointers .

Hi, I want to include a vector representing the sites - environmental data correlation in a PCA. I currently use prcomp (no scaling) to perform the PCA, and envfit to retrieve the coordinates of the environmental data vector. However, the vector length is different from the one obtained in CAnoco when performing a species - environmental biplot (scaling -2). How can I scale the vector in order to

Hi, I'm looking at the "cocktail party" classic problem. I can see how to use ICA to separate the components. But, How do I then create new wav files of the separated sounds so that they can be played?

I have the following code that aligns the two graphs. Problem is that in .pdf it gives me it x-axis (0-100) is broken down into 0-20, 20-40..and so on. I wonder if there is for it to display the x-axis (and y-axis) in more detail than that. I'd appreciate your input -- pdf(file="VECTOR & ICA ALIGNMENT.pdf", height=5, width=5)

Hi, I'm running a Samba 3.0.32 server on AIX 6.1, AIX is authorizing with secldapclntd to an OpenLDAP Server. The Clients are coming from a Windows 2003 Terminal Server Thin Client session, logged in to the domain. I see in the logs that secldapclntd tries 3 times to authorize using DOMAIN\USER as identification, and then finally uses USER(which works). Is this Samba behavior, or AIX? Is

I ran rsync on a combination of Ubuntu and CentOS systems and it doesn't seem to grab all files, such as .cshrc or .bashrc (and they do exist). This makes me wonder what other files rsync may be missing, and how do I tell rsync to grab those missing files? Thanks.
