I am trying to bring data into R from an excel spreadsheet in order to perform several statistical tests on it. I was trying to use odbcConnectExcel in the RODBC package. Once I am connected to the excel file, how do I select rows and columns from the file in order to analysis them in R.

...exe but that wasn't enough to resolve the problem. Are there any other required environment variables for rcmd.exe? I know there are other ways to interace R to a browser but I am currently restricted to the scheme described above.

Sorry to bother everyone, but I've looked in all of the help files and manuals I have and I can't find the answer to this question. I'm doing principle component analysis by calculating the eigen vectors of a correlation matrix that I have that is composed of 21 parameters. I have the eigen vectors and their values that R produced for me but I'm not sure how to tell which

I am trying to search through a matrix I have (x) to see if there are any missing values. This is what I have been using: for (i in 1:3455) for (j in 1:24) if (is.na(x[i,j])) break; i j When I run the program, it either freezes or stops and returns the last entry in the matrix (x[3455,24]). I need to figure out what values in my data matrix are missing because I am using prcomp

Hi all-- A quick question about the dr () function. I am using this function to reduce the dimensions of a data set I have that involves 14 predictor variables and one predictant or response. The goal is to discover which variables play the most important role in determining the response and, thus, to reduce the variables. I would like to use the sliced inverse regression method (SIR) within

Can somebody point me to a HowTO or other documentation describing the tools available under the CentOS 5 KVM package to create and manage a Windows 7 Pro VM?

...e coefficients. (yes, stable using double precision, even though not as stable as lm(). it works just fine with X variables that have >99.99% correlation with as few as 100 observations. if your situation is worse than this, you probably have an error in your data---or you are looking for the Higgs Boson.) I added the code below. feel free to ignore. /iaw ################################################################ ### ### code to test alternatives how fast OLS coefficients can be obtained. ### including tests to exclude missing observations where necessary. ### ### for a more infor...

Hello! I would first like to appologice if this question does not fit on this mailing-list. I am new to Linux and I tried to compile R on my Ubuntu Warty linux. I followed the instructions in "R Installation and Administration" manual. It seams that there was a problem with "configure", since when running "make" afterward gave me this reply: make: *** No

Not sure if it''s been posted yet, my email is currently down... http://weblog.infoworld.com/yager/archives/2007/10/suns_zfs_is_clo.html Interesting piece. This is the second post from Yager that shows solaris in a pretty good light. I particularly like his closing comment: "If you haven''t checked out ZFS yet, do, because it will eventually become ubiquitously implemented
